python - 如何验证生日是否已过？

Question

这与我的上一个问题相似。但是在这里我想知道如何知道一个人是否可以做某事，例如：

如果 joe 不到 21 岁，他就不能喝酒，用生日来告诉你他能不能喝。不使用导入或日历，试图掌握它

到目前为止，这就是我想出的。

dateStr = input("Today's Date: ")
monthStr, dayStr, yearStr = dateStr.split("/")
months = ["January", "February","March", "April", "May", "June", "July", "August","September","October", "November","December"]
monthStr = months[int(monthStr)- 1]
print ("The converted date is:", monthStr, dayStr+",", yearStr)
print("Joe did NOT have his birthday this year!")
Joe's birthday = True
for chr in dateStr:
  tv = True
  if:
    (i<= 13)
    print("Joe is Not allowed to watch TV.")
  else:
    print("Joe is allowed to watch TV.")
driving = True
if:
  (i<= 16)
    print("Joe is NOT Allowed to drive")
else:
  print("Joe is allowed to drive")
  drinking = True 
if:
  (i<= 21)
    print("Joe is NOT allowed to drink.")
else:
  print("Joes is allowed to drink.")

Answer 1

我假设这是一个分配，无论如何检查datetime模块，它真的很方便生成和比较日期。

Answer 2

这似乎是一个分配问题，您还应该检查dateutil.parser，它可以自动转换不同格式的日期，因此您不必自己解析它们。
