我刚开始上大学，我正在为我的大学课写这段代码而且它一直在发送错误。任何启蒙都会有所帮助，也许问题是我半睡半醒。
这是代码
def main():
overtime = int(0)
totaloverpay = float(0)
hours = int(input('How many hours did you work? NOTE** Hours can not exceed 86 or be less than 8 '))
while hours > 86 or hours < 8:
print('ERROR: Insufficient input. Try again')
hours = int(input('How many hours did you work? NOTE** Hours can not exceed 86 or be less than 8 '))
payrate = float(input('What is the payrate per hour for this employee? NOTE** Payrate can not exceed $50.00 or be less than $7.00 '))
while payrate > 50.00 or payrate < 7.00:
print('ERROR: Insufficient input. Try again')
payrate = float(input('What is the payrate per hour for this employee? NOTE** Payrate can not exceed $50.00 or be less than $7.00 '))
workhours(hours, payrate, overtime)
def workhours(hours, payrate, overtime):
if hours > 40:
overtime = (hours - 40) * -1
else:
regtime = hours + 0
paydistribution(hours, payrate, regtime, overtime)
def paydistribution(hours, payrate, regtime, overtime):
if hours >= 40:
halfrate = float(payrate * 0.5)
overpay = halfrate + payrate
totaloverpay = float(overpay * hours)
if hours < 40:
regpay = hours * payrate
display(hours, payrate, regpay, regtime, overtime)
def display(hours, payrate, regpay, regtime, overtime):
total = float(regpay + totaloverpay)
print(' Payroll Information')
print('Payrate :', format(payrate, '0.2f'))
print('Regular Hours :', format(regtime))
print('Overtime Hours:', format(overtime))
print('Regular Pay :', format(regpay, '6.2f'))
print('Overtime Pay :', format(totaloverpay, '7.2f'))
print('Total Pay :', format(total, '7.2f'))
main()

totaloverplay未在其所引用的main下面的任何函数中定义，或者作为全局变量定义。如果您希望它是全局的，请在主要功能范围之外定义它。
答案 1 :(得分：1)
你不应该养成使用global的习惯;这通常表明你正走向错误的方向。相反，使用函数参数和return语句传递显式所需的变量。此外，不要传递他们不需要完成工作的函数参数，并且更喜欢默认参数或显式常量来“魔术数字”。例如：
def workhours(hours, threshold=40):
if hours > threshold:
overtime = hours - threshold
regtime = threshold
else:
overtime = 0
regtime = hours
return regtime, overtime
def paydistribution(payrate, regtime, overtime, otrate=1.5):
regpay = regtime * payrate
overpay = overtime * payrate * otrate
return regpay, overpay
现在main可以致电：
regtime, overtime = workhours(hours)
regpay, overpay = paydistribution(payrate, regtime, overtime)
display(hours, payrate, regpay, regtime, overtime)
这使得流程主要保持在main，同时让其他函数只执行任务的特定位。
在你的位置，我还会考虑使用一个单独的函数来接受用户输入，这些函数循环直到它们提供可接受的东西。适当的定义，例如：
def user_input(prompt, min_, max_):

这似乎是class的一个很好的用例，而不是依赖于函数式编程。
from decimal import Decimal # more precision than floating point
MINIMUM_WAGE = Decimal("7.25")
OVERTIME_RATE = Decimal("1.5")
class Employee(object):
def __init__(self,first,last,MI="",payrate=MINIMUM_WAGE):
self.first = first.capitalize()
self.last = last.capitalize()
self.MI = MI.upper()
if not MI.endswith("."): self.MI += "."
self.payrate = payrate
self.hours = 0
@property
def name(self, reversed_=False):
return "{} {} {}".format(self.first,self.MI,self.last)
@property
def alphabetize(self):
return "{}, {}".format(self.last, self.first)
def payroll(self,numweeks=1):
regularhours = min(40*numweeks,self.hours)
OThours = max(0,self.hours-regularhours)
regularpay = regularhours * self.payrate
OTpay = round(OThours * self.payrate * OVERTIME_RATE,2)
return {"reghours":regularhours,
"overtime":OThours,
"regpay":regularpay,
"OTpay":OTpay,
"total":regularpay + OTpay}
def sethoursworked(self,amt):
self.hours = amt
def display(employee):
payrollinfo = employee.payroll()
print("{:^30}".format("Payroll Information"))
print("{:>30}".format(employee.name))
print("Payrate:{:>22}".format(employee.payrate))
print("Hours:{:>24}".format(payrollinfo['reghours']))
print("Overtime Hours:{:>15}".format(payrollinfo['overtime']))
print("Regular Pay:{:>18}".format(payrollinfo['regpay']))
print("Overtime Pay:{:>17}".format(payrollinfo['OTpay']))
print("-"*30)
print("Total Pay:{:>20}".format(payrollinfo['total']))
Adam = Employee("Adam","Smith","D")
Adam.sethoursworked(51)
display(Adam)
输出：
Payroll Information

Payrate: 7.25
Hours: 40
Overtime Hours: 11
Regular Pay: 290.00
Overtime Pay: 119.62

Total Pay: 409.62

这是另一个清理版本：

while True:
try:
val = float(inp(prompt))
if lo is not None and val < lo:
print("Value must be >= {}".format(lo))
elif hi is not None and val > hi:
print("Value must be <= {}".format(hi))
else:
return val
except ValueError:

def main():

time = min(hours, OVERTIME_CUTOFF)
pay = time * rate
overtime = max(0., hours - OVERTIME_CUTOFF)
overpay = overtime * rate * (1. + OVERTIME_BONUS)
print(dedent("""

像
一样运行How many hours did you work? 46
What is the hourly payrate? 11
