Python One Line for Loops [Tutorial]

List comprehensions in Python allow for concise and efficient creation of lists, simplifying the code by replacing traditional for loops with a single line.

Using list comprehensions, we can transform the way we write functions that require looping through lists. They not only reduce lines of code but also enhance readability.

For example, instead of writing a multi-line function to double values in a list, we can achieve the same outcome in a single line using list comprehension.

List comprehensions take the form of [expression for item in iterable], making code cleaner and easier to understand while maintaining its functionality.
