Given an integer number, find the most frequent digit in it.

  • how to count things efficiently?

  • keep calm and code in Python!

Let use the statistics that comes with python stand library

Statistic Module

This module provides functions for calculating mathematical statistics of numeric (Real-valued) data.

import statistics 
from statistics import mode

This module statistics offers a Single mode (most common value) of discrete or nominal data. The values or method to find this is to convert the vaules into a string and then back again once the frequent digit is found

def freq_digit(num: int) -> int:
    numbers = list(str(num))
    return int(mode(numbers))

Trying out a value

Next we want to test a value

num_list = 12345

Finally

we can run the function with some additional values and input

freq_digit(num_list)

1

freq_digit(12334433)

3

freq_digit(773283277)

7

freq_digit(1121)
