In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
Before the implementation, I would like to discuss why we need to write a parser, even though there are potentially some other ways to do this. Some may suggest that theevalfunction can do this. However, it has been proven that theevalfunction is very dangerous that may only be used for...
Python prides itself on its "batteries-included" motto, but eventually you'll write some special code that you want to share with the world. In this tutorial you'll go through all the stages from an idea all the way to making your package available for anyone to install and use for fun...
To overwrite a file in Python, the “open()” method, “seek() and truncate()”, “re.sub()”, “os.remove()”, “replace()”, and “fileinput()” methods are used. The “open()” method is opened in write mode to overwrite the file in Python. The “os.remove()” function...
