Python `zip()` — Real Examples and When to Use It

# zip pairs up elements from multiple iterables position by position
# and returns an iterator of tuples

import numpy as np

a = np.array([1, 2, 3, 4])

import numpy as np

# Modern way — always use this (NumPy 1.17+)

import numpy as np

a = np.array([1, 2, 3, 4, 5])

import numpy as np

arr    = np.array([1, 2, 3, 4, 5])
