Can you explain more about list slices please?

Question

squares = [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]
print(squares[:7])
print(squares[7:])

i dont understand this code☹️

Answer 1

Python Lists work like this:

sqaures[start:stop:step] -- where "start" is the starting index, "stop" is the stopping index and "step" is the direction and indices to include (this example does not have "step" therefore it defaults to 1)

squares[:7] or squares[0:7] means the first 7 objects in the list, so 0-6. This does not include 7.

squares[7:] or squares[7:-1] means to start listing the objects starting at the 7th position and continue to list all the objects until completion.

I hope this helps. Good Luck
