Sep 16, 2022 · As for the for loop, simply count the number of characters in the input string: num = input("Enter any number : ") print(len(num))

Example 1: Count Number of Digits in an Integer using while loop num = 3452 count = 0 while num != 0: num //= 10 count += 1 print("Number of digits: " + str(count)) Output. Number of digits: 4. In this program, the while loop is iterated until the test expression num != 0 …

Apr 25, 2023 · 3 different ways to find the total number of digits of a number in Python. We will learn how to calculate the digit count by using a while loop, for loop and by calculating the length of the string with the len() method.

Jan 15, 2025 · Learn how to count the number of digits in a number in Python using `len(str())`, loops, and logarithms. This guide includes examples for easy understanding.

3 days ago · Learn how to count the digits in a number using Python with string and non-string methods. Covers integers, floats, negative numbers, loops, and math functions.

Feb 3, 2010 · digits = int(math.log10(n))+1. digits = 1. digits = int(math.log10(-n))+2 # +1 if you don't count the '-' . You'd probably want to put that in a function :) Here are some benchmarks. The len(str()) is already behind for even quite small numbers. timeit len(str(2**100))

Mar 27, 2025 · while loop is the most straightforward to find the number of digits. This is a classic iterative approach. We repeatedly divide the number by 10 (integer division) until it becomes 0. Each time we divide the number, the last digit is removed, and we keep count of it.

Write a Python Program to Count the Number of Digits in a Number using the While Loop, Functions, and Recursion. This Python program allows the user to enter any positive integer. Then it divides the given number into individual digits and counts those individual digits using While Loop. Number = Number // 10. Count = Count + 1.

Apr 9, 2024 · To count in a while loop: Declare a count variable and set it to 0. On each iteration, increment the value of the count variable by 1. count += 1 print(count) # 👉️ 1 2 3 4 5. We declared a count variable and set it to 0. The max_count variable is used in the condition of the while loop.

Using a while loop, get each digit of the number and increment the count each time a digit is obtained. 3. Print the number of digits in the given integer. 4. Exit. Here is source code of the Python Program to count the number of digits in a number. The program output is also shown below. count = count+ 1 .
