Assignment overview This lab exercise provides practice with file processing You will work with a partner on this exercise during your lab session. Two people should work at one computer. Occasionally switch the person who is typing. Talk to each other about what you are doing and why so that both of you understand each step. Mirmir testing: create one file named lab05.py and keep adding your functions to the same file. Part A Leap Year A leap year in the Gregorian calendar system is a year that is divisible by 400 or a year that is divisible by 4 but not by 100. Write a function named leap year that takes one string parameter. It retums True if the string represents a leap year, and retums False otherwise. For example, 1896, 1904, and 2000 are leap years, but 1900 is not. Therefore, leap year ('1896') returns True (Optional challenge: write the function suite as one line.) Demonstrate your completed program to your TA. on-line students should submit the completed program (named "lab05.py") for grading via the Mirmir system. Part B: Rotate Write a function rotate (s, n) that has one string parameter s followed by a positive integer parameter n. It returns a rotated string such that the last n characters have been moved to the beginning. If the string is empty or a single character, the function should simply retum the string unchanged. Assume that n is less than or equal to the length of s and that n is a positive intger. For example rotate ('abcdefgh', 3) returns fghabcde (Optional challenge: write the function to handle n larger than the length of s.O Demonstrate your completed program to your TA. on-line students should submit the completed program (named "lab05.py") for grading via the Mirmir system. Part C: Digit Count Write a function named digit count that takes one parameter that is a number (int or float) and returns a count of even digits, a count of odd digits, and a count of zeros that are to the left ofthe decimal point. Return the three counts in that order: even count, odd count ero count. Be careful of the "edge casc" where the number starts with a decimal point conversion of such a
