Writing a program that takes the month and the day and outputs what season it's in

Write a program that takes a date as input and outputs the date's season. The input is a string to represent the month and an int to represent the day.

Ex: If the input is:

April
11

the output is:

Spring

In addition, check if the string and int are valid (an actual month and day).

Ex: If the input is:

Blue
65

the output is:

Invalid

The dates for each season are:

  • Spring: March 20 - June 20
  • Summer: June 21 - September 21
  • Autumn: September 22 - December 20
  • Winter: December 21 - March 19

Here is my code:

input_month = input()
input_day = int(input())



if input_month == "September" and input_day > 21:
    print("Autumn")
elif input_month == "September" and input_day <= 21:
    print("Summer")
elif input_month == "October":
    print("Autumn")
elif input_month == "November":
    print("Autumn")
if input_month == "December" and input_day >= 21:
    print("Winter")
elif input_month == "December" and input_day <= 20:
    print("Autumn")
elif input_month == "January":
    print("Winter")
elif input_month == "February":
    print("Winter")
if input_month == "March" and input_day >= 20:
    print("Spring")
elif input_month == "March" and input_day <= 19:
    print("Winter")
elif input_month == "April":
    print("Spring")
elif input_month == "May":
    print("Spring")
if input_month == "June" and input_day >= 21:
    print("Summer")
elif input_month == "June" and input_day <= 20:
    print("Spring")
elif input_month == "July":
    print("Summer")
elif input_month == "August":
    print("Summer")
else:
    print("Invalid")

There are two problems with your code.

First, you're printing Invalid after many of the correct results because some of your conditions begin with if instead of elif. Only the first condition in the entire sequence should use if, the rest should all be elif. Because of this, the final else: block only applies to the sequence of conditions from the last if; any date that matched a previous condition will also be reported as Invalid.

Second, you never check for days that are too low or high to be valid days in the month. For example

elif input_month == "October":

should be

elif input_month == "October" and 1 <= input_day <= 31:

That many if statments quickly becomes hard to read. I would suggest using match case to simplify the program. Here is an example

input_month = input("Enter the Month:  ")
input_day = int(input("Enter the Day:  "))

def monthCase(month, day):
    match month:
        case "January" as month:
            return ("Winter")
        case "February" as month:
            return ("Winter")
        case "March" as month:
            if(day < 20):
                return ("Winter")
            else:
                return ("Spring")
        case "April" as month:
            return ("Spring")
        case "May" as month:
            return ("Spring")
        case "June" as month:
            if(day < 21):
                return ("Spring")
            else:
                return ("Summer")
        case "July" as month:
            return ("Summer")
        case "August" as month:
            return ("Summer")
        case "September" as month:
            if(day < 22):
                return ("Summer")
            else:
                return ("Autumn")
        case "October" as month:
            return ("Autumn")
        case "November" as month:
            return ("Autumn")
        case "December" as month:
            if(day < 20):
                return ("Autumn")
            else:
                return ("Winter")
        case _:
            return "Invalid Month"

print (monthCase(input_month, input_day)) #print the result

This is the code I used to get 10/10 on this assignment:

    input_month = input()
    input_day = int(input())

    if input_month == 'March' and 20 <= input_day <= 31:
        print('Spring')
    elif input_month == 'April'and 1 <= input_day <= 30:
        print('Spring')
    elif input_month == 'May' and 1 <= input_day <= 31:
        print('Spring')
    elif input_month == 'June' and 1 <= input_day <= 20:
        print('Spring')

    elif input_month == 'June' and 21 <= input_day <= 30:
        print('Summer')
    elif input_month == 'July' and 1 <= input_day <= 31:
        print('Summer')
    elif input_month == 'August' and 1 <= input_day <= 31:
        print('Summer')
    elif input_month == 'September' and 1 <= input_day <= 21:
        print('Summer')

    elif input_month == 'September' and 22 <= input_day <= 30:
        print('Autumn')
    elif input_month == 'October' and 1 <= input_day <= 31:
        print('Autumn')
    elif input_month == 'November'and 1 <= input_day <= 30:
        print('Autumn')
    elif input_month == 'December' and 1 <= input_day <= 20:
        print('Autumn')

    elif input_month == 'December' and 21 <= input_day <= 31:
        print('Winter')
    elif input_month == 'January' and 1 <= input_day <= 31:
        print('Winter')
    elif input_month == 'February' and 1 <= input_day <= 28:
        print('Winter')
    elif input_month == 'March' and 1 <= input_day <= 19:
        print('Winter')

    else:
        print('Invalid')
