This example demonstrates how to count numeric digits within a string, with functions that either return the count or print it. The code uses Python’s built-in `str.isdigit()` method to check each character, iterating with a `for` loop and maintaining a counter. It tests the function on several sample strings, including those with no numbers, one number, and multiple digits, showing the output for each case. The second function, `how_many_numbers_in_the_word_print`, shows the same logic but uses `print` to display the result directly instead of returning it.
