Lecture 49:- Count Digits In Python

To count the number of digits in a given number in Python, you can convert the number to a string and then calculate the length of the string. Here's an example of how to count the digits in a number:

pythonCopy code

def count_digits(number):    # Convert the number to a string and calculate its length    num_str = str(number)    num_digits = len(num_str)    return num_digits # Example usage: num = 12345 digits_count = count_digits(num) print(f"The number of digits in {num} is: {digits_count}")

Output:

csharpCopy code

The number of digits in 12345 is: 5

In this example, the count_digits() function takes number as input. Inside the function, the str() function is used to convert the number to a string (num_str). Then, the len() function is used to calculate the length of the string, which corresponds to the number of digits in the original number. The function returns the count of digits.

When you call the count_digits() function with num = 12345, it will count the number of digits in 12345, which is 5, and print the result.

Keep in mind that this method counts the total number of digits in the number, including any leading zeros (for integers with leading zeros). If you want to exclude leading zeros, you can use the lstrip() method to remove them before counting the digits.
