Python | Check if a string matches a list of regular expressions

| | |

Method: Using regular expression regex + loop + re.match()
This task can be accomplished using a combination of the above functions. In this, we create a new regex string by concatenating the entire regex list and then match the string against it to check for a match using match () on any element of the regex list.

# Python3 code to demonstrate how it works
# Check if the string matches the regex list
# Using regular expressions join + loop + re.match ()

import re

 
# initializing list

test_list = [ "gee *" , "gf *" , " df. * " , " re " ]

 
# list print

print ( "The original list : " + str (test_list))

 
# initializing test_str

test_str = " pythonengineering "

  
# Check if the string matches the regex list
# Using regex join + loop + re.match ()

temp =   ’(?:% s)’ % ’|’ . join (test_list)

res = False

if re.match (temp, test_str):

res = True

 
# Print result

print ( "Does string match any of regex in list ? : " + str (res))

Output:

 The original list: [’gee *’ , ’gf *’, ’df. *’, ’re’] Does string match any of regex in list?: True
