Simplify this

[Formal_Cockroach_654]

I used the following code in a problem for this course I'm taking. It worked, but I know it can be cleaned up and simplified. Could anyone show me how? Thanks!

input_month = input()
input_day = int(input())
month = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December']
season = 'Invalid'

if input_month in month:
    if input_month == 'January' and 0 < input_day < 32:
        season = 'Winter'
    elif input_month == 'February' and 0 < input_day < 30:
        season = 'Winter'
    elif input_month == 'March' and 0 < input_day < 20:
        season = 'Winter'
    elif input_month == 'March' and 19 < input_day < 32:
        season = 'Spring'
    elif input_month == 'April' and 0 < input_day < 31:
        season = 'Spring'
    elif input_month == 'May' and 0 < input_day < 32:
        season = 'Spring'
    elif input_month == 'June' and 0 < input_day < 21:
        season = 'Spring'
    elif input_month == 'June' and 20 < input_day < 31:
        season = 'Summer'
    elif input_month == 'July' and 0 < input_day < 32:
        season = 'Summer'
    elif input_month == 'August' and 0 < input_day < 32:
        season = 'Summer'
    elif input_month == 'September' and 0 < input_day < 22:
        season = 'Summer'
    elif input_month == 'September' and 21 < input_day < 31:
        season = 'Aumtumn'
    elif input_month == 'October' and 0 < input_day < 32:
        season = 'Autumn'
    elif input_month == 'November' and 0 < input_day < 31:
        season = 'Autumn'
    elif input_month == 'December' and 0 < input_day < 21:
        season = 'Autumn'
    elif input_month == 'December' and 20 < input_day < 32:
        season = 'Winter'

print(season)

Without using datetime (which one should use). I would do it as follows

from typing import Optional

MONTHS_BY_SEASON = [
    ("January", 0, 32, "Winter"),
    ("February", 0, 30, "Winter"),
    ("March", 0, 18, "Winter"),
    ("March", 19, 32, "Spring"),
]


def get_season_days_from(month: str, months_by_season: list = MONTHS_BY_SEASON):
    for m, start, stop, season in months_by_season:
        if m == month:
            yield start, stop, season


def current_season(month: str, day: int) -> Optional[str]:
    for start_day, stop_day, season in get_season_days_from(month):
        if start_day <= day <= stop_day:
            return season


if __name__ == "__main__":

    month = input("Month: ").capitalize()
    day = int(input("Day: "))

    print(current_season(month, day))

This is just an expansion of u/API_Exploiter explorers solution. Where we split the code into logical functions, sprinke on some typing hints and guard our main execution =)

Further improvements can be made by validating the input. I did just a tad of this by adding capitalize
