如何根据用户输入制作日期时间对象？

Question

我正在尝试制作一个闹钟。如何根据用户输入创建日期时间对象，其中用户输入分别为小时、分钟和秒。例如：

from datetime import datetime

# user-input: at 2:30
hr = "2"
m = "30"
s = "0"

Answer 1

from datetime import datetime
def GetDate():
    isValid=False
    while not isValid:
        userIn = input("Type Date dd/mm/yy: ")
        try: # strptime throws an exception if the input doesn't match the pattern
            d = datetime.datetime.strptime(userIn, "%d/%m/%y")
            isValid=True
        except:
            print("Invalid")
    return d

#test the function
print(GetDate())
