Creating a program that records speed in a speed trap

[astonavfc]

That is my code so far it says my subtraction is wrong can you point out anything I can do better.

Thanks.

from datetime import datetime
#Function to convert date from string to dateTime
def dateTimeIn(timestamp):
    dateTimeIn = datetime.strptime(strDateIn, "%d/%m/%Y %H:%M%S")
    return dateTimeIn
def dateTimeOut(timestamp):
    dateTimeOut = datetime.strptime(strDateOut, "%d/%m/%Y %H:%M%S")
    return dateTimeOut   

#Main Program   
myFileIn=open("CameraIn.txt","rt")
myFileOutput=open("Output.txt","rt")
for lineIn in myFileIn:
    lineIn=myFileIn.readline()
    theListIn=lineIn.split(",")
    regIn=theListIn[0]
    strTimeIn=theListIn[1]
    myFileOut=open("CameraOut.txt","rt")
    for lineOut in myFileOut:
        lineOut=myFileOut.readline()
        theListOut=lineOut.split(",")
        regOut=theListOut[0]
        strTimeOut=theListOut[1]
        if regIn==regOut:
            dateTimeIn-dateTimeOut

When you have an error you should include the error traceback.
dateTimeIn and dateTimeOut are function that need to be called by placing () at the end with a timestamp between those brackets.
In the functions the variable names need looking at to match the input variable.

error traceback, sorted out the names just stuck with subtracting

Error:

It tells me timestamp is needed so I enter it than says timestamp is not defined?

from datetime import datetime
#Function to convert date from string to dateTime
def dateTimeIn(timestamp):
    dateTimeIn = datetime.strptime(strTimeIn, "%d/%m/%Y %H:%M:%S")
    return dateTimeIn
def dateTimeOut(timestamp):
    dateTimeOut = datetime.strptime(strTimeOut, "%d/%m/%Y %H:%M:%S")
    return dateTimeOut
   

#Main Program   
myFileIn=open("CameraIn.txt","rt")
myFileOutput=open("Output.txt","rt")
for lineIn in myFileIn:
    lineIn=myFileIn.readline()
    theListIn=lineIn.split(",")
    regIn=theListIn[0]
    strTimeIn=theListIn[1]
    myFileOut=open("CameraOut.txt","rt")
    for lineOut in myFileOut:
        lineOut=myFileOut.readline()
        theListOut=lineOut.split(",")
        regOut=theListOut[0]
        strTimeOut=theListOut[1]
        if regIn==regOut:
            dateTimeIn(timestamp)-dateTimeOut(timestamp)

Error:

I have to get the timestamp from the file and I want it to do this for every timestamp that shows that the car is speeding?

Variable names need to match. the ones you pass to a function need to have already been assigned a value. The variable names used in the function that is from a passed in value need to match the function parameters.

def somefunction(variableinside):
   print(variableinside)

Variableoutside = 'testing'
somefunction(variableoutside)

Is is possible for you to edit my code to work, sorry but I'm not very good at python
Thanks for your help! -This is unfinished and once this is working I will finish it off

however, some people are willing to program for money, office space with window views and freebies, etc   we have another forum for posting such opportunities

    myFileOut=open("CameraOut.txt","rt")
    for lineOut in myFileOut:
        lineOut=myFileOut.readline()

Why are you reading from an output file?  Why are you reading each line twice?  Why don't you ever close any of the files you open?
We can't help if the code doesn't make sense.  It's like asking us to help you fix the food you're cooking, after you've already covered it with curry.  Sure it can still work, but why make us do all that extra work?
