Combine Lists with Zip

Python Easy 24 views

Combine Lists with Zip is a classic Python data-shaping problem. You are given two lists, one for keys and one for values, and you need to return a dictionary pairing each key with its corresponding value by position. The intended solution style is straightforward and Pythonic, using zip() and dict() rather than manual index loops.

The important behavior is one-to-one positional mapping. First key maps to first value, second to second, and so on. The judge includes different data types for keys and values (strings, ints, booleans) plus empty-list input. Your function should return an actual dictionary object, not a list of tuples or a printed string representation.

Keep the implementation clean and deterministic: same inputs must always give the same mapping. Since this challenge is focused on basic transformation fluency, prioritize readability and correctness over complex abstractions. In short, pair items by index, build the dictionary directly, and return the final object in the expected Python format the checker compares against.
