Write a program with the following functions: def digits (n) - that returns the number of digits in a given number def firstDigit (n) - that returns the first digit of a given number . Ex: If the input is: Enter a digit: 1729 the output is: The number of digits in 1729 is 4 The last digit of 1729 is 9 . where digit is a value >= 0. Then write main () to: get input for the digit, call the functions, and print output. Comments have been included as a writing guide and the call to main() is included. *Hint: You will want to convert your numbers to a string in each function so you can use available string methods.
