Python 3.x 未定义名称“是”

当我进一步了解代码时，它告诉我没有定义Yes。代码询问用户他们工作了多长时间并计算代码

我试着对那句话做了一些小改动。它给了我同样的结果

当用户回答“是”时；我想要代码来计算工资总额

Overtimeflag = 50

if Overtimeflag == 50: 

 Overtimeflag = True

Else:

Overtimeflag = False


Name = input('Whats your first and last name')

Address = input('Whats your address')

HoursWorked=float(input('How many years have you been working here'))

Overtime=float(input('how long did you work today'))

if HoursWorked > 40:

   print('You are qualified for overtime pay')

elif Overtime >= 2:

    Overtime = HoursWorked - 40

else:

    print('In order to earn overtime, the user must have worked for at least 2 years')

grossPay =float(input('Whats your hourly rate'))

Overtimeflag =input('Did you work 50 hours this week')

##Calculate the gross pay with the following formula

if grossPay == Yes:

    Overtime2 * grossPay * 2 + HoursWorked - Overtimeflag * grossPay

else:

    print('You do not earn overtime due to lack of years of service')

---

Yes必须是字符串，因为前面没有定义它

输出：

---

如果你发布你的实际代码，这会有所帮助。。。我们不是魔术师。你的代码还有其他问题。您将grossPay与Yes进行比较，但grossPay是一个浮动输入“您的小时费率是多少”。什么是超期？

Overtimeflag = 50

if Overtimeflag == 50: 
 Overtimeflag = True
else:
    Overtimeflag = False


Name = input('Whats your first and last name')

Address = input('Whats your address')

HoursWorked=float(input('How many years have you been working here'))

Overtime=float(input('how long did you work today'))

if HoursWorked > 40:
   print('You are qualified for overtime pay')
elif Overtime >= 2:
    Overtime = HoursWorked - 40
else:
    print('In order to earn overtime, the user must have worked for at least 2 years')
grossPay =float(input('Whats your hourly rate'))
Overtimeflag3 =input('Did you work 50 hours this week')
##Calculate the gross pay with the following formula

if Overtimeflag3 == "Yes":
    Overtime2 = grossPay * 2 + HoursWorked - Overtimeflag * grossPay
    print("Overtime pay: ",Overtime2 )
else:
    print('You do not earn overtime due to lack of years of service')
