Python: use string replace function - how it works

The string replace method is very practical in Python, with which you can easily exchange substrings. This practical tip shows you how to use the function.

Python: use string replace function - how it works

The string replace function is already integrated in Python and does not have to be imported by you.

• First of all you have to store a string with a variable. For example, "string1 =" This is a sample string "".
• The syntax of this method is "string1.replace (old, new [, max])". The old substring to be replaced is represented by "old". The new string is stored at "new". You can use the "max" argument to specify the maximum number of replacements.
• An example would be the command "print (string1.replace (" This ", " That "))". As a result, you would now get "This is a sample string".
