Code:
A = [[2,3],[3,4], [5,2]]
B = [[1,2],[3,2]]
result=[];
for i in range(len(A)):
#AA=[];
for j in range(len(B)):
AA.append(0)
print("AA=",(AA,i,j))
result.append(AA)
print(f"result at {i}",result)
The output for this code:
AA= ([0], 0, 0)
AA= ([0, 0], 0, 1)
result at 0 [[0, 0]]
AA= ([0, 0, 0], 1, 0)
AA= ([0, 0, 0, 0], 1, 1)
result at 1 [[0, 0, 0, 0], [0, 0, 0, 0]]
AA= ([0, 0, 0, 0, 0], 2, 0)
AA= ([0, 0, 0, 0, 0, 0], 2, 1)
result at 2 [[0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0]]
Why has the code not given me [[0, 0], [0, 0, 0, 0], [0, 0, 0, 0, 0, 0]] output result at 2, as the final result for my code when I comment #AA=[] this empty list from the code. Can anyone explain to me clearly the concept of appending lists in this code?
