Quick Answer
Comprehensions create collections concisely. List: [expr for item in iterable if condition]. Dict: {k: v for k, v in items}. Set: {expr for item in iterable}. Generator: (expr for item in iterable) - lazy, memory efficient. More readable and often faster than equivalent for loops. Avoid deeply nested comprehensions - they become hard to read.
