1. Use List Comprehensions

List comprehensions are a concise and readable way to create new lists from existing ones. They provide a more efficient alternative to traditional for loops and allow you to write compact code that is easy to understand.

Here is an example of using a for loop to create a new list of squares:

numbers = [1, 2, 3, 4, 5]
squared_numbers = []
for number in numbers:
    squared_numbers.append(number ** 2)

The same result can be achieved using list comprehension:

numbers = [1, 2, 3, 4, 5]
squared_numbers = [number ** 2 for number in numbers]

As you can see, the list comprehension is shorter, more readable, and easier to understand.

2. Leverage Generators

Generators are a way to create iterators in Python. They provide a way to iterate over a large dataset without loading the entire dataset into memory. This can greatly improve performance, especially when working with large amounts of data.
