#PYTHON REGEX CHEAT SHEET DRIVER#
# Driver program to test the above function Return contains(text, pat, text_index+1, pat_index) # If current characters of pat and tex don't match If exactMatch(text, pat, text_index, pat_index): # If current characters of pat and text match # This function returns true if 'text' contain 'pat'ĭef contains(text, pat, text_index, pat_index): Return exactMatch(text, pat, text_index+1, pat_index+1) # Else If last character of pattern reaches If text_index = len(text) and pat_index != len(pat): You can also use it in an if statement to check if there is a match or notīetween a regex and a string with 're.match(regex, string)'# Recursive Python3 program to find if a given pattern isĭef exactMatch(text, pat, text_index, pat_index): String where there is a digit, followed by a digit, followed by a digit, followed If we search for \d\d\d-\d\d\d-\d\d\d\d, it will look for anywhere in the In regex, if we use \d, it will look for any digit in your string (0-9) The r in front of the string means it's a raw string (/n, /t, etc doesn't work) Mobile_string = 'My number is 41' # Not real numberĪny_phone_numbers = phone_num_arch(mobile_string) # Let's say you want to check for a phone number in a string # Returns text with all matches replaces with other text Print("Not any match") # Example import re
If re.match(reg, text): #Check if regex is correct Let's define this Python Sample Code: import re In this Article we will go through Regex In Python using code in Python.
