Which are the top built-in functions in Python?

1. zip(): Combines multiple iterables (e.g., lists, tuples) into an iterator of tuples. Useful for pairing elements from multiple collections.

names = ['VK', 'MSD', 'RS']
scores = [85, 92, 88]

# Pairing names with scores
paired = list(zip(names, scores))
print(paired)  # Output: [('VK', 85), ('MSD', 92), ('RS', 88)]

2. enumerate(): Adds a counter to an iterable, useful when you need the index along with the value in loops.

fruits = ['apple', 'banana', 'cherry']

for index, fruit in enumerate(fruits):
    print(index, fruit)

# Output:
# 0 apple
# 1 banana
# 2 cherry

3. map(): Applies a function to every item in an iterable and returns a map object (which is iterable). It’s great for…
