Python List Replace. generate link and share the link here. The filter() function accepts only two parameters. String manipulation is very essential for a python developer. It follows this template: string[start: end: step]Where, start: The starting index of the substring. It returns a Boolean (either True or False) and can be used as follows:This operator is shorthand for calling an object's __contains__ method, and also works well for checking if an item exists in a list.
