Functions to preprocess and normalize text.

The product of Solo System by NewBornTown(NewBorn-Town). With over 100 million users worldwide, Solo Launcher is one of the Top 3 Launchers in the category on Google Play. With its array of DIY features, the launcher enables you to customize the user interface on a device so it works in the way you want. It takes up only a small amount of space yet it can boost device performance by restoring. You either paste in the text from a spreadsheet or word-processor. Choose the type of text cleaning you want to perform. Clean the text so it shows you a Preview of the changed text; Either copy the text to the clipboard, update the results back into the database, export the results, or resubmit the text for further cleaning.

Project description

User-generated content on the Web and in social media is often dirty. Preprocess your scraped data with clean-text to create a normalized text representation. For instance, turn this corrupted input:

1. K5 ## 5 sally f 0 How can we be certain? K6 ## 6 greg m 0 There is no way. K7 ## 7 sam m 0 I distrust you. K8 ## 8 sally f 0 What are you talking about? K9 ## 9 researcher f 1 Shall we move on?
2. The latest installation package occupies 1.3 MB on disk. The latest version of Text Cleanup is supported on PCs running Windows XP/7/8, 32-bit. Text Cleanup is included in Office Tools. The following version: 2.0 is the most frequently downloaded one by the program users. The program's installer is commonly called Text Cleanup.exe.

Installation

To install the GPL-licensed package unidecode alongside:

You may want to abstain from GPL:

NB: This package is named clean-text and not cleantext.

If unidecode is not available, clean-text will resort to Python's unicodedata.normalize for transliteration.Transliteration to closest ASCII symbols involes manually mappings, i.e., ê to e.unidecode's mapping is superiour but unicodedata's are sufficent.However, you may want to disable this feature altogether depending on your data and use case.

To make it clear: There are inconsistencies between processing text with or without unidecode.

Usage

Carefully choose the arguments that fit your task. The default parameters are listed above.

You may also only use specific functions for cleaning. For this, take a look at the source code.

So far, only English and German are fully supported. It should work for the majority of western languages. If you need some special handling for your language, feel free to contribute. 🙃

Development

Install and use poetry.

Contributing

If you have a question, found a bug or want to propose a new feature, have a look at the issues page.

Pull requests are especially welcomed when they fix bugs or improve the code quality.

If you don't like the output of clean-text, consider adding a test with your specific input and desired output.

Until now error messages haven't been more than mentioned, but if you have triedout the examples you have probably seen some. There are (at least) twodistinguishable kinds of errors: syntax errors and exceptions.

8.1. Syntax Errors¶

Syntax errors, also known as parsing errors, are perhaps the most common kind ofcomplaint you get while you are still learning Python:

The parser repeats the offending line and displays a little ‘arrow' pointing atthe earliest point in the line where the error was detected. The error iscaused by (or at least detected at) the token preceding the arrow: in theexample, the error is detected at the function print(), since a colon(':') is missing before it. File name and line number are printed so youknow where to look in case the input came from a script.

8.2. Exceptions¶

Even if a statement or expression is syntactically correct, it may cause anerror when an attempt is made to execute it. Errors detected during executionare called exceptions and are not unconditionally fatal: you will soon learnhow to handle them in Python programs. Most exceptions are not handled byprograms, however, and result in error messages as shown here:

The last line of the error message indicates what happened. Exceptions come indifferent types, and the type is printed as part of the message: the types inthe example are ZeroDivisionError, NameError and TypeError.The string printed as the exception type is the name of the built-in exceptionthat occurred. This is true for all built-in exceptions, but need not be truefor user-defined exceptions (although it is a useful convention). Standardexception names are built-in identifiers (not reserved keywords).

The rest of the line provides detail based on the type of exception and whatcaused it.

The preceding part of the error message shows the context where the exceptionoccurred, in the form of a stack traceback. In general it contains a stacktraceback listing source lines; however, it will not display lines read fromstandard input.

Built-in Exceptions lists the built-in exceptions and their meanings.

8.3. Handling Exceptions¶

It is possible to write programs that handle selected exceptions. Look at thefollowing example, which asks the user for input until a valid integer has beenentered, but allows the user to interrupt the program (using Control-C orwhatever the operating system supports); note that a user-generated interruptionis signalled by raising the KeyboardInterrupt exception.

The try statement works as follows.

• First, the try clause (the statement(s) between the try andexcept keywords) is executed.

• If no exception occurs, the except clause is skipped and execution of thetry statement is finished.

• If an exception occurs during execution of the try clause, the rest of theclause is skipped. Then if its type matches the exception named after theexcept keyword, the except clause is executed, and then executioncontinues after the try statement.

• If an exception occurs which does not match the exception named in the exceptclause, it is passed on to outer try statements; if no handler isfound, it is an unhandled exception and execution stops with a message asshown above.

A try statement may have more than one except clause, to specifyhandlers for different exceptions. At most one handler will be executed.Handlers only handle exceptions that occur in the corresponding try clause, notin other handlers of the same try statement. An except clause mayname multiple exceptions as a parenthesized tuple, for example:

A class in an except clause is compatible with an exception if it isthe same class or a base class thereof (but not the other way around — anexcept clause listing a derived class is not compatible with a base class). Forexample, the following code will print B, C, D in that order:

Note that if the except clauses were reversed (with exceptB first), itwould have printed B, B, B — the first matching except clause is triggered.

The last except clause may omit the exception name(s), to serve as a wildcard.Use this with extreme caution, since it is easy to mask a real programming errorin this way! It can also be used to print an error message and then re-raisethe exception (allowing a caller to handle the exception as well):

The try … except statement has an optional elseclause, which, when present, must follow all except clauses. It is useful forcode that must be executed if the try clause does not raise an exception. Forexample:

The use of the else clause is better than adding additional code tothe try clause because it avoids accidentally catching an exceptionthat wasn't raised by the code being protected by the try …except statement.

When an exception occurs, it may have an associated value, also known as theexception's argument. The presence and type of the argument depend on theexception type.

The except clause may specify a variable after the exception name. Thevariable is bound to an exception instance with the arguments stored ininstance.args. For convenience, the exception instance defines__str__() so the arguments can be printed directly without having toreference .args. One may also instantiate an exception first beforeraising it and add any attributes to it as desired.

Exception handlers don't just handle exceptions if they occur immediately in thetry clause, but also if they occur inside functions that are called (evenindirectly) in the try clause. For example:

8.4. Raising Exceptions¶

The raise statement allows the programmer to force a specifiedexception to occur. For example:

The sole argument to raise indicates the exception to be raised.This must be either an exception instance or an exception class (a class thatderives from Exception). If an exception class is passed, it willbe implicitly instantiated by calling its constructor with no arguments:

If you need to determine whether an exception was raised but don't intend tohandle it, a simpler form of the raise statement allows you tore-raise the exception:

8.5. Exception Chaining¶

The raise statement allows an optional from which enableschaining exceptions by setting the __cause__ attribute of the raisedexception. For example:

This can be useful when you are transforming exceptions. For example:

The expression following the from must be either an exception orNone. Exception chaining happens automatically when an exception is raisedinside an exception handler or finally section. Exception chainingcan be disabled by using fromNone idiom:

8.6. User-defined Exceptions¶

Programs may name their own exceptions by creating a new exception class (seeClasses for more about Python classes). Exceptions should typicallybe derived from the Exception class, either directly or indirectly.

Exception classes can be defined which do anything any other class can do, butare usually kept simple, often only offering a number of attributes that allowinformation about the error to be extracted by handlers for the exception. Whencreating a module that can raise several distinct errors, a common practice isto create a base class for exceptions defined by that module, and subclass thatto create specific exception classes for different error conditions:

Most exceptions are defined with names that end in 'Error', similar to thenaming of the standard exceptions.

Many standard modules define their own exceptions to report errors that mayoccur in functions they define. More information on classes is presented inchapter Classes. Internet new version free download.

8.7. Defining Clean-up Actions¶

The try statement has another optional clause which is intended todefine clean-up actions that must be executed under all circumstances. Forexample:

If a finally clause is present, the finallyclause will execute as the last task before the trystatement completes. The finally clause runs whether ornot the try statement produces an exception. The followingpoints discuss more complex cases when an exception occurs:

• If an exception occurs during execution of the tryclause, the exception may be handled by an exceptclause. If the exception is not handled by an exceptclause, the exception is re-raised after the finallyclause has been executed.

• An exception could occur during execution of an exceptor else clause. Again, the exception is re-raised afterthe finally clause has been executed.

• https://ice-torrent.mystrikingly.com/blog/update-safari-browser. If the try statement reaches a break,continue or return statement, thefinally clause will execute just prior to thebreak, continue or returnstatement's execution.

• If a finally clause includes a returnstatement, the returned value will be the one from thefinally clause's return statement, not thevalue from the try clause's returnstatement.

For example:

A more complicated example:

As you can see, the finally clause is executed in any event. TheTypeError raised by dividing two strings is not handled by theexcept clause and therefore re-raised after the finallyclause has been executed.

In real world applications, the finally clause is useful forreleasing external resources (such as files or network connections), regardlessof whether the use of the resource was successful.

8.8. Predefined Clean-up Actions¶

Some objects define standard clean-up actions to be undertaken when the objectis no longer needed, regardless of whether or not the operation using the objectsucceeded or failed. Look at the following example, which tries to open a fileand print its contents to the screen.

The problem with this code is that it leaves the file open for an indeterminateamount of time after this part of the code has finished executing.This is not an issue in simple scripts, but can be a problem for largerapplications. The with statement allows objects like files to beused in a way that ensures they are always cleaned up promptly and correctly.

After the statement is executed, the file f is always closed, even if aproblem was encountered while processing the lines. Objects which, like files,provide predefined clean-up actions will indicate this in their documentation.
