Understanding List Comprehensions
List comprehensions provide a concise way to create lists. They consist of square brackets containing an expression followed by a for clause, then zero or more for or if clauses. The expressions can be anything, meaning you can put all types of objects in lists.
Here’s a simple example:
squared_numbers = [x**2 for x in range(10)]
This will create a list of squared numbers from 0 to 9.
Why Use List Comprehensions?
- Readability: They make it clear and easy to understand.
- Expressive: One liner for complex operations.
- Efficiency: Generally faster than traditional loops.
