Is it possible to append to a in this case?And how

Question

class X :
def __init__(self):
self.a = []
self.b = []
self.c = []

X.a.append(1) wont work

Answer 1

Make <a>, <b> and <c> become class member, define them in global space

class X:
a = []
b = []
c = []

for i in range( 1, 43 ):
X.a.append( i )
print(X.a)

(Edit)
You already have the answer in your earlier post

Answer 2

In this case you have to instantiate an X object first:
x = X()
x.a.append()
