I keep getting a Traceback error, can someone help me fix that? There may be additional errors, but I can't get past that one too. EOFError: EOF when reading a line

SCENARIO:

Have 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

MY CODE:

input_month = input()

input_day = int(input())

if input_month == 'March' and 20 <= input_day <= 31\

or input_month == 'April' and 1 <= input_day <= 30\

or input_month == 'May' and 1 <= input_day <= 31\

or input_month == 'June' and 1 <= input_day <= 20:

print('Spring')

elif input_month == 'June' and 21 <= input_day <= 30\

or input_month == 'July' and 1 <= input_day <= 31\

or input_month == 'August' and 1 <= input_day <= 31\

or input_month == 'September' and 1 <= input_day <= 30:

print('Summer')

elif input_month == 'September' and 22 <= input_day <= 30\

or input_month == 'October' and 1 <= input_day <= 31\

or input_month == 'November' and 1 <= input_day <= 30\

or input_month == 'December' and 1 <= input_day <= 20:

print('Autumn')

elif input_month == 'December' and 21 <= input_day <= 31\

or input_month == 'January' and 1 <= input_day <= 31\

or input_month == 'February' and 1 <= input_day <= 28\

or input_month == 'March' and 1 <= input_day <= 19:

print('Winter')

else:print('Invalid')
