  • Q1. What is zip function
  • Ans. 

    The zip function in Python is used to combine multiple iterables into a single iterable of tuples.

    • Zip function takes two or more iterables as arguments and returns an iterator of tuples where the i-th tuple contains the i-th element from each of the input iterables.

    • If the input iterables are of different lengths, the resulting iterator will only have as many elements as the shortest input iterable.
