#Because import calendar is far too easy. #when you hit run you'll be asked for input. #Please enter the year on the first line. #Hit return to move to the next line. #On the second line, please enter 1 to print the first half of the year or 2 to print the second half. #Example: #2000 #1 #Would print Jan - Jun of the year 2000. #Should be able to print any year between 1000 and 9999. #All calendars will be built using the Gregorian Calendar. #Comments with bug reports and/or suggestions on ways to overcome the timeout limit, so an entire year can be printed in 1 run would be appreciated. #Enjoy! #PS: This is an extention of my "Find The Day of the Week for a Given Date" code. from __future__ import print_function import math import sys #User Input try: year = list(input()) half = int(input()) except ValueError: print("The second line was not a number") sys.exit() except EOFError: print("Invalid Input") sys.exit() #Establishing length of Year Input if len(year) > 4: print("Too many characters in year") sys.exit() elif len(year) < 4: print("Not enough characters in year") sys.exit() #Invalid Years try: yyyy = int("".join(year)) except ValueError: print("Invalid Year") sys.exit() #Shoutout to Sean VanMeter for finding the bug corrected below if yyyy < 1000: print("Year cannot be less than 1000") sys.exit() #CALCULATING THE 1ST DAY OF THE 1ST MONTH #Calculating the Starting Month if half == 1: month = 1 elif half == 2: month = 7 elif half < 1: print("Line 2 was greater than 2") sys.exit() elif half < 2: print("Line 2 was less than 1") sys.exit() #Some Variables day = 1 yy1 = int(year[0] + year[1]) yy2 = int(year[2] + year[3]) #Calculating a Value for the Month monthKeys = [0, 3, 3, 6, 1, 4, 6, 2, 5, 0, 3, 5] monthCode = monthKeys[month -
