In this section you learned that:
A list comprehension is an expression that creates a list by iterating over another container.
A basic list comprehension:
[i*2 for i in [1, 5, 10]]
Output: [2, 10, 20]
List comprehension with if condition:
[i*2 for i in [1, -2, 10] if i>0]
Output: [2, 20]
List comprehension with an if and else condition:
[i*2 if i>0 else 0 for i in [1, -2, 10]]
Output: [2, 0, 20]
