Could anyone help to explain below code? why have such difference if i put "results" in different Position in a loop.

Question

#Position1:
#results=[]
for i in range(2):
#Position2:
results=[]
for j in range(3):
#Position3:
#results=[]
results.append(i+j)
print(results)

Why the results in Position1,2,3 have different output?

Answer 1

Position 1: results is created once and the sum of i and j is appended every time j is incremented => [0, 1, 2, 1, 2, 3]

Position 2: results is created anew/overridden each time i is incremented => [1, 2, 3]

Position 3: results is created anew/overridden each time j is incremented => [3]

You can play around with this code to see the difference:
