Python: What does the use of [] mean here?

Question

What is the difference in these two statements in python?

var = foo.bar

and

var = [foo.bar]

I think it i

Answer 1

I think it is making var into a list containing foo.bar but I am unsure. Also if this is the behavior and foo.bar is already a list what do you get in each case?

• Yes, it creates a new list.

• If foo.bar is already a list, it will simply become a list, containing one list.

  h[1] >>> l = [1, 2]
  h[1] >>> [l]
  [[1, 2]]
  h[3] >>> l[l][0]
  [1, 2]
