在一个函数中需要帮助解决这个问题

Question

我在计算机科学课上有一项作业，需要帮助修复一个函数，但我不知道出了什么问题!函数名为"days_left"。该函数接受三个变量:Day、Month和Year。它应该输出当年还剩下多少天。我已经尽力了，但还是想不明白!任何帮助都将不胜感激。脚本如下:

def leap_year(year):
if (year % 4) == 0:
if (year % 100) == 0:
if (year % 400) == 0:
return True
else:
return False
else:
return True
else:
return False


def number_of_days(month, year):
days31 = [1, 3, 5, 7, 8, 10, 12]
days30 = [4, 6, 9, 11]
if month in days31:
return 31
elif month in days30:
return 30
else:
if not leap_year(year):
return 28
else:
return 29

def days_left(month, day, year):
days = 0
for i in range(1, month):
days += number_of_days(i, year)
days += day
for x in range(year):
if leap_year(year):
return 366 - days
else:
return 365 - days
if __name__ == '__main__':
print("Please enter a date: n")

d = int(input("Day: "))
m = int(input("Month: "))
y = int(input("Year: "))

print("nMenu:")
print("1) Calculate the number of days in the given month.")
print("2) Calculate the number of days left in the given year.")
selection = int(input())

if selection == 1:
print(number_of_days(m, y))
elif selection == 2:
print(days_left(d, m, y))
else:
print('')

Answer 1

def days_left(day, month, year):

应该是'day, month'而不是'month, day'，因为您正在使用days_left(d, m, y)调用函数
