Introduction

The task is to find the maximum number from the alphanumeric string.

Program

import re  
    
def max_ele(ip_str):  
 
    ele = map(int,re.findall("\d+",ip_str))  
    return max(ele) 
        
ip_str = input("Enter the string: ")
print("The maximum number in the string {0} is {1}". format(ip_str, max_ele(ip_str)))

Output

Explanation

In the above python code the steps followed are:

• We have used re.findall() method to extract the numeric value from the given string. The re.findall() method takes expression and string as the argument. We passed expression as ‘\d+’, it returns one or more digit values.
• We have used map() function to convert the numbers to integer.
• And returned the max element using max() function.
