Using 'self' in classes seems pretty straight forward. My curiosity is
why I have to use it. Shouldn't it be implied? If I create an instance
of 'human' called 'bruce' and call the method 'blink' why do I have to
pass bruce into the method e.g.
class human:
...code
def blink(self,times):
for i in range(times):
if self.eye_is_closed:
self.eye_open()
self.eye_close()
else:
self.eye_close()
self.eye_open()
def eye_open(self):
...code
def eye_close(self):
...code
bruce = human()
bruce.blink(5)
blink is a method of bruce because bruce is an instance of human.
Reading this silly code I can understand what is going on if self was
not included. Can anyone enlighten me as to why we have self?
by the way..six months of python and I'm 10 times the programmer I was
with vb
