Comprehensions (in programming)

Comprehensions in programming are concise ways to create or transform lists, sets, or dictionaries. They allow you to generate new collections by applying an expression to each item in an existing one, often with optional filtering. For example, a list comprehension can quickly produce a list of squares from numbers 1 to 5, using a single line of code. This approach improves readability and efficiency, making code shorter and more expressive compared to traditional loops. Comprehensions are a powerful tool for data manipulation, enabling clear and concise data processing within a program.
