Determining the Length of Digits within an Integer in Python

In Python, obtaining the count of digits within an integer is a straightforward process. The technique involves temporarily converting the integer into a string using the str() function, and then using the len() function to determine the length of the string. For instance, if you want to find the number of digits in the integer 123, you can convert it to a string using str(123), which results in '123'. Then, you can use len('123') to obtain the length, which is 3.

Therefore, the following code snippet provides an example of how you can determine the number of digits in an integer:

<code class="python">num = 123
string_num = str(num)
digit_count = len(string_num)
print("Number of digits:", digit_count)</code>

In this example, the variable num stores the integer value 123. The str() function converts the integer into the string '123', which is stored in the variable string_num. Finally, the len() function is applied to string_num to determine the number of digits, which is 3, and this value is printed to the console using the print() function.
