Python | Program that matches a word containing ‘g’ followed by one or more e’s using regex
Prerequisites : Regular Expressions | Set 1, Set 2
Given a string, the task is to check if that string contains any g followed by one or more e’s in it, otherwise, print No match.
Examples :
Input : geeks for geeks
Output : geeks
geeks
Input : graphic era
Output : No match
Approach : Firstly, make a regular expression (regex) object that matches a word which contains ‘g’ followed by one or more e’s, then pass a string in the findall method. This method returns the list of the matched strings. Loop through the list and print each matched word.
\w – represent Any letter, numeric digit, or the underscore character.
* means zero or more occurrence of the character.
+ means one or more occurrence of the character.
Below is the implementation :
# Python program that matches a word # containing ‘g’ followed by one or # more e’s using regex # import re pakages import re # Function check if the any word of # the string containing 'g' followed # by one or more e's def check(string) : # Regex \w * ge+\w * will match # text that contains 'g', followed # by one or more 'e' regex = re.compile("ge+\w*") # The findall() method returns all # matching strings of the regex pattern match_object = regex.findall(string) # If lenght of match_object is not # equal to zero then it contains # matched string if len(match_object) != 0 : # looping throgh the list for word in match_object : print(word) else : print("No match") # Driver Code if __name__ == '__main__' : # Enter the string string = "Welcome to geeks for geeks" # Calling check function check(string) |
