So it will execute themethod code block, where we’ve initialized thevariable to get the number of digits in the number, like this:digit_count = len(str(num)). Then, we call the is_armstrong() method, which takes two parameters for number and digit_count:is_armstrong(num, digit_count...

Theisdigit()methods returnsTrue, if all the characters in the string are digits. If not it will returnFalse. Example: print(' '.isdigit())#Falseprint('123'.isdigit())#Trueprint('1.23'.isdigit())#Falseprint('abc'.isdigit())#False ...
