Take a string with some numbers, and then we will find the number which has occurred a maximum number of times. We will use regex to do so.
Python Regex also called REs or regular expressions is a module using which we can specify rules to set the possible strings to match. It is available in re module.
Using findall() and counter() method
In this method, we will find the numbers within the input string using re.findall() method. Then we will count the occurrence of each number using a counter() from the collection module.
