Python Regex model: Here, we will figure out how to expel driving zeros from an IP address utilizing Python program?
Given an IP address as information, compose a Python program to expel driving zeros from it.
Input: 216.08.094.196 Output: 220.127.116.11 Input: 216.08.004.096 Output: 18.104.22.168
In this program, we are utilizing the sub() method of “re” module.
re.sub(pattern, repl, string, count=0, flags=0)
The sub() in the capacity represents SubString, a specific normal articulation design is looked in the given string(3rd parameter), and after finding the substring design is supplanted by repl(2nd parameter), tally checks and keeps up the occasions this happens.
# Python program to Remove leading zeros from an IP address # import re module # re module provides support # for regular expressions import re # Make a regular expression for # finding leading zeros in ip address regex = '\.*' # Define a function for Remove # leading zeros from an IP address def removeLeadingZeros(ip): modified_ip = re.sub(regex, '.', ip) print(modified_ip) # Main code if __name__ == '__main__' : # Enter ip address ip = "216.08.094.196" # call function removeLeadingZeros(ip) ip = "216.08.004.096" removeLeadingZeros(ip)
