Thanks a lot.
Why this difference of behavior between list(a) and [a]?
Because they are different things.
list is a function that takes an iterable & creates a list out of it.
The [...] syntactic form takes a list of arguments and returns a list
composed of them.
You see the difference maybe with this:
a = 1
foo = [a]
bar = list(a)
->
Traceback (most recent call last):
File "/tmp/test.py", line 5, in <module>
bar = list(a)
TypeError: 'int' object is not iterable
