围绕日期时间导入的混淆（字符串和日期）

Question

我真的被我的代码的这一部分困住了，如果能从其他人那里得到一些输入，那就太棒了。这部分不是我写的，我也无法联系写这部分的人（这是一个小组项目）。当您没有正确格式化输入时它确实会出现错误（我们不需要为这个项目做验证所以我不会担心），但我担心的是这些错误：

Traceback (most recent call last):
  File "/Users/mycomputer/PycharmProjects/project/main.py", line 46, in <module>
    stringsdates()
  File "/Users/mycomputer/PycharmProjects/project/main.py", line 29, in stringsdates
    birthmonth = birthday.month
AttributeError: 'str' object has no attribute 'month'

非常感谢任何帮助<3 我真的不知道从哪里开始这部分代码。顺便说一下代码：

import datetime

def yearadd(date):
    test = datetime.timedelta(days=365)
    return date + test

def stringsdates():
    # Inputs for first and last name, start date and birthday along with yearly salary.

    firstname = input("What is your first name? ")
    lastname = input("What is your last name? ")
    startdate = input("What is the date you started with the company? (YYYY MM DD) ")
    birthday = input("What is your birthday? (YYYY MM DD) ")
    yearlysal = input("What is your yearly salary? ")

    # ♡ Processing
    startdate = datetime.datetime.strptime(startdate, "%Y %m %d")
    birthdate = datetime.datetime.strptime(birthday, "%Y %m %d")
    yearhired = startdate.year
    birthmonth = birthday.month
    today = datetime.datetime.today()

    formatfullname = (firstname + lastname + ", " + firstname[0] + "." + lastname + ", " + lastname + ", " + firstname[
        0] + ".")
    employeenum = firstname.upper()[0] + lastname.upper()[0] + "-" + str(yearhired) + "-" + str(birthmonth)
    reviewdate = yearadd(yearhired)
    nextbday = today - birthdate

    # ♡ Output
    print(formatfullname)
    print(employeenum)
    print(reviewdate)
    print(nextbday)
    print(yearlysal)

您正在尝试将出生月份读取为 birthday.month，其中生日是您从用户那里读取的字符串，并且由于该字符串类型没有与之关联的月份属性，因此您得到错误。您可能打算使用的是转换后的日期时间对象 birthdate.

birthmonth = birthdate.month
