Why does this errp occur?
"Attributeerror: 'list' Object has no attribute 'apend'" with this code?
class Stack :
def __init__(self) :
self.items = []
def push(self, item) :
self.items.apend(item)
def pop(self) :
return self.items.pop()
def isEmpty(self) :
return (self.items == [])
s = Stack()
s.push(54)
print s.pop()

It was just a typo. You forgot a 'p' in "append"
Change
self.items.apend(item)
for
self.items.append(item)
Also, you need to move this block back to the correct scope.
s = Stack()
s.push(54)
print s.pop()
The final code would look like this
class Stack :
def __init__(self) :
self.items = []
def push(self, item) :
self.items.append(item)
def pop(self) :
return self.items.pop()
def isEmpty(self) :
return (self.items == [])
s = Stack()
s.push(54)
print(s.pop())
