# Simplifying Lists with List Comprehensions

`List Comprehensions` allow you to create lists using `for loops` and `conditional statements` **in a single line of code**.

```python title="Structure of List Comprehensions"
[expression for item in iterable]
```

<br />

## Utilizing List Comprehensions

List comprehensions are written inside square brackets (`[]`) with an expression, a for loop, and optionally an if condition.

This allows you to generate new lists based on existing iterables like lists or tuples.

```python title="Example of List Comprehension"
numbers = [1, 2, 3, 4, 5]
squared = [num ** 2 for num in numbers]

print("squared:", squared)
# [1, 4, 9, 16, 25]
```

<br />

List comprehensions are used to apply operations to each item of an existing list to generate a new list, or to create a new list including only items that meet specific conditions.

```python title="List Comprehension with Condition"
numbers = [1, 2, 3, 4, 5]
# Include only even numbers
even_numbers = [num for num in numbers if num % 2 == 0]

print(even_numbers)
# [2, 4]
```

Using the `for` loop in list comprehension allows you to iterate over each element of an existing list, creating a new list.
