我正在学习python，我无法弄清楚这段代码有什么问题？

Question

正如我在标题中所说。 当我尝试运行它时，它显示以下内容。 第 30 行：SyntaxError：错误输入 (' ')
上面引用的代码如下。 我只需要在这里做一点宣传，这样我就可以发布这个了。

 #Samuel Davis, module 3 exam, 12/9/19

    #Declare variables    

    dayPay = 18.50 
    evePay = 20.00
    nightPay = 23.50
    retire = 0.02



    #Prompt inputs from user

    employeeShift = int(input("What shift do you work? 1=Day 2=evening 3=night."))
    weekHour = int(input("How many hours did you work this week?"))

    #Begin prep

    if grossShift==1:
        employeePay=dayPay*weekHour    
    elif employeeShift==2:
        grossPay=evePay*weekHour
    elif employeeshift==3:
        grossPay=nightPay*weekHour
    else: 
        employeePay=0

    #Finalize calculations & get retirement deduction

    if employeeShift==1
        retireDed=0
        print("You cannot get a retirement deduction in the day shift")
    else
        retireDed=employeePay*retire

    netPay=employeepay-retireDed

    print(totalPay)

您有一些语法错误/未声明的变量。 我已尽力重新构建/编辑我认为您至少要拥有一个可运行的脚本的内容：

#Declare variables    
dayPay = 18.50 
evePay = 20.00
nightPay = 23.50
retire = 0.02

#Prompt inputs from user
employeeShift = int(input("What shift do you work? 1=Day 2=evening 3=night."))
weekHour = int(input("How many hours did you work this week?"))

#Begin prep
if employeeShift==1:
    employeePay=dayPay*weekHour    
elif employeeShift==2:
    grossPay=evePay*weekHour
elif employeeshift==3:
    grossPay=nightPay*weekHour
else: 
    employeePay=0

#Finalize calculations & get retirement deduction
if employeeShift==1:
    retireDed=0
    print("You cannot get a retirement deduction in the day shift")
else:
    retireDed=employeePay*retire
netPay=employeePay-retireDed
print(netPay)
