Python Program to Count Number of Digits in a Number

In this example, you will learn to get the input from the user then count number of digits from user inputted number and finally print out the result.

Example 1 : Using While Loop

    
#Python Program to Count Digits From Number
count = 0
number = int(input("Enter a number :: "))

while (number > 0):
    number = number//10
    count = count + 1

print("Total number of digits : ", count)
       

Output :

    
Enter a number :: 123569
Total number of digits :  6
    

Example 2 : Using in-built methods

    
#Python program to count digits from number using in-built methods
count = 0
number = int(input("Enter a number :: "))

print("Total number of digits : ", len(str(abs(number))))
       

Output :

    
Enter a number :: 1234569
Total number of digits :  7
