Here is a Python function to make gradients in 2d

import numpy as np

def make_gradient(x, y, dx, dy):
    """
    Make gradient in 2D.

    >>> make_gradient(x, y, dx, dy)
    """
    return (dx, dy)

# Enter the x, y, dx, dy
x = 1
y = 2
dx = 3
dy = 4

# Calling the function
print((make_gradient(x, y, dx, dy)))

#Example Output
# (3, 4)

#Remember to inspect code for bugs.
