What is zip in Python

The zip() function in Python takes iterable, bundles them to a tuple. This function finally returns the bundled up tuple

Syntax: zip(iterables)

iterables – can be built-in iterable or user defined iterable.

• If no iterable is passed, the function returns an empty iterator
• If one iterable is passed, it returns an iterator of tuples with each tuple having only an element.
• When multiple iterables are passed, it returns an iterator of tuples with each tuple having elements from all the iterables.

Example:

a = ("red", "blue", "green")
b = ("black", "white")

#using zip to map values
x = zip(a,b)

#converting values to print as list
print(list(x))

Output:

[('red', 'black'), ('blue', 'white')]
