waitTime=0.5
def is_ava():
waitTime = waitTime + 0.1
print waitTime
if __name__ == '__main__':
is_ava()
Why UnboundLocalError: local variable 'waitTime' referenced before assignment , I have declared waitTime.

To modify global variable, you need to declare it inside the function as a global variable:
waitTime=0.5
def is_ava():
global waitTime # <--------
waitTime = waitTime + 0.1
print waitTime
if __name__ == '__main__':
is_ava()

What if I want to modify a `global` name in two different functions? Do I have to declare it in each function? – zyy Mar 14 '19 at 15:58
