python 我的年龄计算器有问题

Question

我想要代码以这种格式打印人的年龄和出生日期（你 31 岁，你是星期五出生的）但我在代码中遇到问题说（参数'fmt'未填充：11）

代码：

import datetime


def ma(birthdate):
    today = datetime.date.today()
    age = today.year - birthdate.year - ((today.month, today.day) < (birthdate.month, birthdate.day)), birthdate.strftime('%A')
    return age


print('You are', ma(datetime.date(int(input('Please Enter a Year: ')), int(input('Please Enter a Month: ')),
                                  int(input('Please Enter a Day: ')))), 'years old, and you have born in', datetime.date.strftime('%A'))```

输出：

Please Enter a Year: 2007
Please Enter a Month: 8
Please Enter a Day: 17
Traceback (most recent call last):
  File "C:\Users\walee\AppData\Roaming\JetBrains\PyCharmCE2021.3\scratches\age calculate.py", line 11, in <module>
    int(input('Please Enter a Day: ')))), 'years old, and you have born in', datetime.date.strftime('%A'))
TypeError: descriptor 'strftime' for 'datetime.date' objects doesn't apply to a 'str' object

Process finished with exit code 1```

Answer 1

简单胜于复杂。 (Python的禅)

age = ma(datetime.date(int(input('Please Enter a Year: ')),
                       int(input('Please Enter a Month: ')),
                       int(input('Please Enter a Day: '))))

print(f'You are {age[0]} years old and you were born on {age[1]}')

输出：

Please Enter a Year: 2007
Please Enter a Month: 8
Please Enter a Day: 17
You are 14 years old and you were born on Friday
