Number of Digits in a Number in Python using Recursion

The recursion technique can also be used to count the number of digits in a number. Recursion is a method of defining a function that includes a call to itself. The recursive function allows us to break down a complex problem into identical single simple cases that we can easily handle.

Program:

# Python program to count number of digits in a number

# Function for count number of digits
count = 0
def count_Digits(num):
    global count
    if(num > 0):
        count = count + 1
        count_Digits(num // 10)
    return count

# input
num = int(input('Enter any number: '))
    
# printing number of digits
print('Number of digits:', count_Digits(num))

Output:

Enter any number: 456
Number of digits: 3
