Can you explain Python Regular Expression Syntax in a simple way?

PythonServer Side ProgrammingProgramming

A regular expression is a sequence of character(s) mainly used to find and replace patterns in a string or file. 

Python Regular expression Syntax uses two types of characters −

  • Meta characters: As the name suggests, these characters have a special meaning, similar to * in wild card. 

  • Literals (like a,b,1,2…)

Python regular expressions use raw strings, quantifiers, character classes, groups, alternation and such syntactic tools to work
