A program that takes a date as input and outputs the date's season in the northern hemisphere is; done using input as a string to represent the month and an int to represent the day.
How to Program in Python
The seasons in the northern hemisphere are Spring, Summer, Autumn and Winter.
Now, the dates for each of these seasons are;
Spring: March 20 - June 20
Summer: June 21 - September 21
Autumn: September 22 - December 20
Winter: December 21 - March 19
Using the given information of input as a string to represent the month and an int to represent the day and combining with the seasons above, we can write the program in python as;
input_month = input()
input_day = int(input())
months= ('January', 'February','March', 'April' , 'May' , 'June' , 'July' , 'August' , 'September' , "October" , "November" , "December")
if not(input_month in months):
print("Invalid")
elif input_month == 'March':
if not(1<=input_day<=31):
print ("Invalid")
elif input_day<=19:
print("Winter")
else:
print ("Spring")
elif input_month == 'April' :
if not(1<=input_day<=30):
print("Invalid")
else:
print("Spring")
elif input_month == 'May':
if not(1<=input_day<=31):
print("Invalid")
else:
print("Spring")
elif input_month == 'June':
if not(1<=input_day<=30):
print("Invalid")
elif input_day<=20:
print ("Spring")
else:
print("Summer")
elif input_month == 'July' or input_month == 'August':
if not(1<=input_day<=31):
print("Invalid")
else:
print("Summer")
elif input_month == 'September':
if not(1<=input_day<=30):
print("Invalid")
elif input_day<=21:
print ("Summer")
else:
print ("Autumn")
elif input_month == "October":
if not(1<=input_day<=31):
print("Invalid")
else:
print("Autumn")
elif input_month == "November":
if not(1<=input_day<=30):
print("Invalid")
else:
print ("Autumn")
elif input_month == "December":
if not(1<=input_day<=31):
print("Invalid")
elif input_day <=20:
print ("Autumn")
else:
print ("Winter")
elif input_month == 'January':
if not(1<=input_day<=31):
print("Invalid")
else:
print("Winter")
elif input_month == "February":
if not(1<=input_day<=29):
print("Invalid")
else:
print ("Winter")
