What can I do to stop getting some 'local unbound' error message? [duplicate]

Local (?) variable referenced before assignment [duplicate]

3 answers

I am getting an error saying "UnboundLocalError: local variable 'numberOfTripsCompleted' referenced before assignment"

trips= 0

def increasetrips(x):

    trips += 1

so I construct a list: ['driver', firstname, lastname,vehicletype, trips].
After instantiating this with an example: ['driver', Bob, Brown, truck, 0], I now want to have a function to increase the 'trips' part of the list by 1 each time. The function I have above does not give an error, but it after running ' increasetrips', when I call back for my instantiated list, position 4 still holds '0'. So it keeps returning ['driver', Bob, Brown, truck, 0], when i am expecting ['driver', Bob, Brown, truck, 1]

That code does not contain any variable named numberOfTripsCompleted. Please post the actual code.

Try this.

trips= 0

def increasetrips(trips):

     trips += 1

     return trips

trips = increasetrips(trips)

The parameter x you are passing inside the function. And then using trips which is defined outside the function

That runs perfectly fine for me. Though I have made some changes which will help you understand the flow.
