PYTHON IDLE
1) Write a Python program that takes as input a month and year (as integer numbers) and determines the number of days in the month, and prints them to the output. Thirty days are in September, April, June, and November. All the rest are 31 except for February which could be 28 or 29 depending upon whether the year is a leap year or not. Consider a year a leap year if it is evenly divisible by 4.
2) Write a Python program that asks users to input 10 float numbers (using a while statement), and print the minimum number.
3) Write a Python program that asks users to input an integer number and print the summation of its digits and total number of its digits. (i.e., for n=35, sum is 3+5=8, and total number of digits is 2.
4) Write a simple calculator python program that prints the following menu:
1. Addition
2. Subtraction
3. Multiplication
