In this article, you'll learn how to trim a string in Python using the You'll also see how to use the Let's get started! Python has three built-in methods for trimming leading and trailing whitespace and characters from strings. Each method returns a new trimmed string. When the So, if you have whitespace at the start and/or end of a word or phrase, The following variable To remove both of them, you use the

How to Remove Leading and Trailing Characters from Strings in PythonThe The characters you add as arguments specify what characters you would like to remove from the start and end of the string. Below is the general syntax for this case:
The characters you specify are enclosed in quotation marks. So, for example, say you have the following string:
You want to remove "H" and "?", which are at the beginning and at end of the string, respectively. To remove them, you pass both characters as arguments to
Notice what happens when you want to remove "W" from "World", which is at the middle and not at the start or end of the string, and you include it as an argument:
It will not be removed! Only the characters at the start and end of said string get deleted. That being said, look at the next example. Say you want to remove the first two and the last two characters of the string:

You would do the following:
Same goes for whitespace. Taking again the example from earlier, this time the whitespace would be removed only from the end of the output:
