Here is a Python function to linearly interpolate between two points in 3d

import numpy as np

def interpolate_3d(point1, point2, t):
    """Interpolate between two points in 3d."""
    return (1-t)*point1 + t*point2

# Enter the two points
point1 = np.array([1,2,3])
point2 = np.array([4,5,6])

# Enter the value of t
t = 0.5

# Calling the function
print((interpolate_3d(point1, point2, t)))

#Example Output
# [2.5 3.5 4.5]

#Remember to inspect code for bugs.
