Determining the Number of Digits in an Integer

Finding the number of digits in an integer is a common task in programming. In Python, there are various methods to accomplish this.

Method: String Conversion

As mentioned in the provided answer, one straightforward approach is to convert the integer to a string using the str() function. The length of the resulting string represents the number of digits in the original integer. For instance, len(str(123)) will give 3.

Example:

number = 1345
digit_length = len(str(number))
print("Number of digits:", digit_length)

Output:

Number of digits: 4

This method is simple and works reliably for any integer value.
