Python program to check whether a regular expression is present in string or not

Submitted by Shivang Yadav, on March 10, 2021

The regular expression in Python is a search pattern formed by a sequence of characters.

The match() method is used to check whether the given pattern is matched to the string. It is defined using the re library.

Syntax:

regex.match(regexPattern, string, flag (optional) )

Let's take an example to understand the problem,

Input:
string = "learn python programming language at includehelp" ; pattern = '(.*) at (.*?)'

Output:
Match Found

Program to illustrate the working of out solution

import re

myString = "learn python programming language at includehelp"

matchObj = re.match( r'(.*) python (.*?) .* ', myString, re.M|re.I)

if matchObj:
    print("Match Found ")
else:
    print("No Matches are found")

Output:

Match Found
