Write Pythonic Code with List Comprehensions

If you are still writing three-line for loops just to filter a list or transform some data, it is time to embrace list comprehensions. They make your code more concise and often faster to execute. For example, using a single line to square a list of numbers is much easier to read at a glance than a nested loop with an append call. Just remember to keep them readable—if the logic gets too complex, a standard loop is better for the sake of your future self's sanity.
