Python Loops and List Comprehension Connection

Question

How loops and list comprehension are connected in python? Explain with examples.

Answer 1

Here a documentation about List Comprehensions and Loops

Loops are used for iterating through Lists, Tuples and other Iterables

items = [1, 3, 6]
for item in items:
    print(item)

> 1
> 3
> 6

List Comprehensions are used for creating new lists from another Iterable

items = [1, 3, 6]
double_items = [item * 2 for item in items]
print(double_items)

> [2, 6, 12]

You can also filter items with List Comprehensions like this

items = [1, 3, 6, 8]
even_items = [item for item in items if item % 2 == 0]
print(even_items)

> [6, 8]
