出现名称错误 NameError，函数未定义？

Question

File "/Users//Desktop/A5/driverModule.py", line 22, in controller tripInfo() NameError: name 'tripInfo' is not defined

Okay I'm really stuck and can't figure out why I'm getting this error. Any help is appreciated.

Driver Module

while i == "y":
    getDistance()
    getEarningpPerMile()
    getDrivingTime()
    getBreakTime()
    getFuelConsumed()
    getCostperGallon()
    tripInfo()

    i = input("Would you like to add a new trip? Enter y to add a new trip, "
          "or enter n to exit.")

Answer 1

This is just one of the reasons that * imports are discouraged. Start by being explicit here

from TripInfoModule import tripInfo, ...

If that line can't find tripInfo , then you have got closer to the bug sooner.

Now tripInfo is defined in the thing you call "Module2"

This file of course needs to be named "TripInfoModule". Make sure there are no old versions or .pyc files that could be loaded instead of the one you are expecting
