Advanced Comprehensions in Python
Python supports list, dict, set, and generator comprehensions — all providing a concise way to create collections from existing ones.
Nested comprehensions can flatten 2D data or build matrix-style structures. They are equivalent to nested for loops but written in one line.
Conditional comprehensions can filter (if at end) or use ternary logic (if...else in the middle) to transform values differently.
Comprehensions are generally faster than equivalent for loops because Python optimises them internally. Use them when the logic is simple enough to read easily.
Advanced Comprehensions — Syntax
# List comprehension with condition
[expr for item in iterable if condition]
# Ternary in comprehension
[a if condition else b for item in iterable]
# Dict comprehension
{key: value for item in iterable}
# Nested comprehension (flatten 2D list)
[x for row in matrix for x in row]
