Hello. Can someone explain it to me?

Question

I see a python-challenge: List comprehension can be used to ... ? Tge right answer is ' construct a list'.

Answer 1

You can fill a list with items, for example:

list_ = []
for i in range(10):
list_.append(int(input())

This creates a list and after that fills it with ten numbers the user inputs.

Now a list comprehension is a shortcut:

list_ = [int(input()) for i in range(10)]

Answer 2

I don't know how the term was intended originally. I understand it like:

'A comprehensive way to build a list'

(like an all-in-one package, you don't have to do each step separately).

You can use it for other container types as well:

# assuming you have two containers keys and values
{key: value for key in keys for value in values}

tuple(n * 2 for n in range(100))

etc.

Answer 3

What does it mean this term?: List comprehension?

Answer 4

I have understood . It is a generator. Thank you.
