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.
groups, and metacharacters. You can define intricate patterns to split strings in ways that go beyond simple character delimiters. When you’re dealing with complex string-splitting requirements, especially with multi-delimiter scenarios, usingre.split()is the right tool to handle the job effectively...
The easiest and most efficient way to convert a string to an integer in Python is to use the “int()” function. It accepts a valid string integer literal as an argument and returns an integer. For example, int(“456”) would return 456. Basic conversion Define a valid string that is...

The%operator defines the data type of the variable. Different letters are used to define different data types. For example, if the variable is a decimal, we will use the%doperator. If it is a string, we will use the%soperator, and so on. ...
There are different techniques which can be deployed to get this done in Python viz. The Loop Method Using the Regular Expression The Iterator & Join Technique Each listed method works on an exclusive logic to define the input string and then remove the vowels associated with it. In simpler ...
Custom filters are Python functions that take one or two arguments: The value of the variable (input) – not necessarily a string. The value of the argument – this can have a default value, or be left out altogether. For example, in the filter {{ var|foo:"bar" }}, the filter foo...
