Question

What are the core algorithms used in the code below?

Provide examples for small inputs

(This code Takes a year and a month as input. Prints 28-31 days paired with the corresponding days of the week. Takes into account leap years. Keeps logs of user input and resulting calendars)

# Tuples list for each month along with their date ranges

calendar = [('January', 31), ('Feburary', 28), ('March', 31),

('April', 30), ('May', 31), ('June', 30),

('July', 31), ('August', 31), ('September', 30),

('October', 31), ('November', 30), ('December', 31)]

# Days of the week

week = ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat']

def create_calendar(year, start_day):

# Determines the current starting position on the calendar

start_point = week.index(start_day)

# If leap year occurs, Feburary date range changes to 29

if leap_year(year):

calendar[1] = ('Feburary', 29)

for month, days in calendar:

print('{0} {1}'.format(month, year).center(25, ' ')) # Prints Month Titile

print(' '.join(['{0:<3}'.format(w) for w in week])) # Prints Day Headings

print('{0:<4}'.format('') * start_point, end='') # Adds spacing for non-zero starting point

for day in range(1, days + 1):

print('{0:<4}'.format(day), end='') # Prints day number

start_point += 1

if start_point == 7: # If the starting point is sunday (7), start a new line

print()

start_point = 0 # Will reset counter

print('\n')

def leap_year(year):

# Checks if a year is a leap year

if year % 4 == 0:

if year % 100 == 0:

if year % 400 == 0:

return True

else:

return False

else:

return True

else:

return False

year = int(input('Enter The Year: \n'))

print()

if year <= 0: # If number inputed is less than or equal to zero, creates 'Invalid Input'

print('Invlid Input')

import sys

sys.exit()

start_day = input('Enter Start Day Of The Year: Sun, Mon, Tue, Wed, Thu, Fri, Sat: \n',)

print()

create_calendar(year,start_day)
