how to work with variables changed in definitions

[Prof_Jar_Jar]

Hi there,

I've used Python in school for like two years, so I really don't know what I'm doing. Excuse that please and don't worry about my messy code.

I'm currently coding to check a wether a click was performed on the right tile.
I've gotten so far, that I can spawn in images to give feedback to the user, but I also want to count the times, the user is clicking the wrong tile.

My problem is, that I defined "wrong" as following:

    def wrong (wx,wy):
        window.blit(wrongpng, (wx,wy))
        lcchange = -1

this is called upon in this:
(Yes, I'm using actual pixel numbers, but I will change that after testing(also ignore my suboptimal code))

    def a(av):
        mposx, mposy = pygame.mouse.get_pos()
        if av == 1:
            if mposx >= tx+16 and mposx <= tx+26 and mposy >= ty+16 and mposy <= ty+26:
                rectangle (tx+16, ty+16, 10, 10, GREY)
        if av == 2:
            if mposx >= tx+27 and mposx <= tx+37 and mposy >= ty+16 and mposy <= ty+26:
                wrong(wx,wy)
        if av == 3:
            if mposx >= tx+38 and mposx <= tx+48 and mposy >= ty+16 and mposy <= ty+26:
                wrong(wx,wy)
        if av == 4:
            if mposx >= tx+49 and mposx <= tx+59 and mposy >= ty+16 and mposy <= ty+26:
                wrong(wx,wy)
        if av == 5:
            if mposx >= tx+60 and mposx <= tx+70 and mposy >= ty+16 and mposy <= ty+26:
                rectangle (tx+60, ty+16, 10, 10, GREY)

which is called in this:

    for av in range (6):
        a(av)
        av = av+1

because I wanted to change the Lifecounter in this:

     Lifecounter = Lifecounter + lcchange
     lcchange = 0

I've tested with print in every imaginable place and I've realized, that in the instant I return to the a for-loop that the lcchange variable is back to 0 although it changed it to -1 in the "wrong def"

So my question is:
How do I solve this properly?

Thanks in advance for any help!

You return it.

def wrong (wx,wy):
    window.blit(wrongpng, (wx,wy))
    lcchange = -1
    return lcchange

And then assign it where you call it: lcchange = wrong(wx, wy).

Thanks so much!!
