Sometimes, while working with python, we can have a problem in which we need to check for substrings occurring in consecutive repetition. This can have application in data domains. Lets discuss a way in which this task can be performed.
Method : Using max() + re.findall()
The combination of above methods can be used to perform this task. In this, we extract the substrings repetitions using using findall() and extract the maximum of them using max().
# Python3 code to demonstrate working of # Maximum Consecutive Substring Occurrence# Using max() + re.findall()import re # initializing stringtest_str = 'geeksgeeks are geeks for all geeksgeeksgeeks' # printing original stringprint("The original string is : " + str(test_str)) # initializing subs sub_str = 'geeks' # Maximum Consecutive Substring Occurrence# Using max() + re.findall()res = max(re.findall('((?:' + re.escape(sub_str) + ')*)', test_str), key = len) # printing result print("The maximum run of Substring : " + res) |
The original string is : geeksgeeks are geeks for all geeksgeeksgeeks The maximum run of Substring : geeksgeeksgeeks
