"unboundlocalerror: Local Variable Referenced Before Assignment" When Incrementing Variable In Function

I am getting this error and I've read other posts but they say to put global before dollars = 0 which produces a syntax error because it doesn't allow the = 0. I'm using dollars as

Solution 1:

You need to add global dollars, like follows

def search():
    global dollars
    print('You gain 5 bucks')
    dollars = dollars + 5
    shop()

Everytime you want to change a global variable inside a function, you need to add this statement, you can just access the dollar variable without the global statement though,

defshop():
    global dollars
    shop = input("Enter something: ")
    if shop == 'Shortsword':
        if dollars < 4:          # Were you looking for dollars?print('I\'m sorry, but you don\'t have enough dollars to buy that item.')
            shop1()
        if dollars > 4:
            print('Item purchased!')
            dollars -= someNumber # Change Number hereprint('You now have ' + dollars + ' dollars.')

You also need to reduce the dollars, when you shop for something!

P.S - I hope you're using Python 3, you'll need to use raw_input instead.

Solution 2:

You need to put global dollars, on a line on its own, inside any function where you change the value of dollars. In the code you've shown that is only in search(), although I assume you'll also want to do it inside shop() to subtract the value of the item you buy...
