UnboundLocalError: local variable referenced before assignment
Question:
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.
Python version: 2.7
Answers:
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()
waitTime=0.5
def is_ava():
waitTime = waitTime + 0.1
print waitTime
if __name__ == '__main__':
is_ava()
