The function close() closes an open file. For example: f = open('my_file', 'r+') my_file_data = f.read() f.close() The above code opens 'my_file'in read mode then stores the data it reads from my_file in my_file_data and closes the file. When you open a file, the operating system gives a file handle to read/write ... Read More

For a pure python module you can find the location of the source files by looking at the module.__file__. For example,  >>> import mymodule >>> mymodule.__file__ C:/Users/Ayush/mymodule.py  Many built in modules, however, are written in C, and therefore module.__file__ points to a .so file (there is no module.__file__ on Windows), and ...

The function reload(moduleName) reloads a previously loaded module (assuming you loaded it with the syntax "importmoduleName" without exiting the script. It is intended for conversational use, where you have edited the source file for a module and want to test it without leaving Python and starting it again. For example, ... Read More

You can use regexes to remove the ANSI escape sequences from a string in Python. Simply substitute the escape sequences with an empty string using re.sub(). The regex you can use for removing ANSI escape sequences is: '(\x9B|\x1B\[)[0-?]*[ -\/]*[@-~]'.For example, import re def escape_ansi(line):     ansi_escape =re.compile(r'(\x9B|\x1B\[)[0-?]*[ -\/]*[@-~]')   ...

Unless you re-raise the exception right away – we ... Read More

Only a single except clause in a try block is invoked. If you want the exception to be caught higher up then you will need to use nested try blocks.Let us write 2 try...except blocks like this:try: try: 1/0 except ArithmeticError as e: if str(e) == "Zero division": print ("thumbs ... Read More
