How to get define a variable within a function without reseting it

Question

I'm currently making a music quiz. I have come across a problem and don't know how to solve it. I'm using a variable called wrong. It is supposed to be an int, if I define it at the begin of the code it won't transfer into the function. And if define it in the function it resets.

pass the variable as function parameter and return it at the end of the function — Florian H, Dec 05 '18 at 14:50

You can define the function without first creating the variable, or not, Python can handle either case.

def music(answers):
    # Where answers is [(user input, correct answer) ...]
    wrong = []
    for i in answers:
        if i[0] == i[1]:
            pass
        else:
          wrong.append(i)  
    return wrong

wrong = music(answers)

Or if you want to pick up where you left off with previous values for answers and wrong:

wrong = [(previous values, previous answers) ...]

def music(answers, wrong = []):
    # Where answers is [(user input, correct answer) ...]
    wrong = []
    for i in answers:
        if i[0] == i[1]:
            pass
        else:
          wrong.append(i)  
    return wrong

wrong = music(answers, wrong=wrong)

Easy. Make it global. When you define wrong at the beginning like this

wrong = 10

Just call global inside the function and it should use the initialized variable

def your_function(): 
    global wrong
    wrong_temp = wrong
    #use wrong_temp however

I would also take a look at this link. It looks like this might solve the question you are asking, but it is also helpful to understand how global variables work. Using global variables in a function

Function names are usually written like `your_function` – Charles Landau Dec 05 '18 at 15:07
