Why is Python making a mistake?

[emmalee]

I'm trying to do different tasks for the python, doing this.To write a function of a date that takes 3 arguments - day, month and year. Get True back if that date is in our calendar, and False is different."

I want to accomplish this task so (code )

def date(day, month, year):
if year % 2 == 1: # Проверяем год, на високосность
    if month <= 12: # Проверяем месяц, правильное ли количество месяцев
        if month != 2:
            if month % 2 == 0: # Проверяем месяц, (30 или 31 дней)
                if day <= 30: # Проверяем день на правильность их количества в месяце
                    return True
        elif month == 2:
            elif:
                else:
                    return False
else:
    return False

elif year % 2 == 0:

elif month <= 12:

elif month == 2:

elif month % 2 == 0:

elif day <= 29:

return True

else:

return False

else:

return False
date(10, 5, 2021)

Makes a mistake: "File "MY WAY," line 7
return True
TabError: inconsistent use of tabs and spaces in indentation."♪ I didn't find a tabulation error. That's why I can't do it.

I suggest that we look towards the solution using the datetime module:

from datetime import date
def check_date(y, m, d):

try:

date(y, m, d) # Проверяем получается ли дата из наших значений

return True

except:

return False
print(check_date(2018, 2, 28)) # True, есть в календаре

print(check_date(2018, 2, 29)) # False, нет в календаре
