Python NoneType object is not callable (beginner)

Question

It tells me line 1 and line 5 (new to debugging/programming, not sure if that helps)

def hi():
    print(\'hi\')


def         


        

Answer 1

Why does it give me that error?

Because your first parameter you pass to the loop function is None but your function is expecting an callable object, which None object isn't.

Therefore you have to pass the callable-object which is in your case the hi function object.

def hi():     
  print 'hi'

def loop(f, n):         #f repeats n times
  if n<=0:
    return
  else:
    f()             
    loop(f, n-1)    

loop(hi, 5)
