Hello,
I am new to OOP. I'm a bit confused about the following code.
class Clock(object):
def __init__(self, time):
self.time = time
def print_time(self):
time = '6:30'
print(self.time)
Local name 'time' is bound to '6:30'.
Attribute 'time' of the 'self' instance is bound to '5:30' because of
the call and initization. You asked to print the latter. If you write
'print(time)' you will see '6:30'.
clock = Clock('5:30')
clock.print_time()
5:30
I set time to 6:30, but it's coming out to 5:30. I guess it's because I
passed in 5:30, so, it's replaced?
How does line-by-line execution run inside a frame? How does __init__ work?
I understand you must have __init__. Is it run before print_time(), if so,
why don't I just set self.time = '6:30' instead of self.time = time?
Thanks!
