Question

I would pass a variable between two def inside a function. How can i do? i tried using global but didn’t work

class example:

 def funz1(self,q,b):
    global queue
    queue = []
    queue += [q]
    queue += [a]

 def funz2(self):
    return str(queue.pop())

but it said me that queue is an empty list

Answer 1

You have to use the self parameter, which points to the example instance itself:

class example:    
 def funz1(self,q,b):
    self.queue = []
    self.queue += [q]
    self.queue += [a]

 def funz2(self):
    return str(self.queue.pop())

Also, as a side note, array += [item] is wrong, you should use array.append(item)
