I have a time series 3d coordinates (x, y, z) that are time stamped in 1s and 2s for example. I need to find the corresponding 3d coordinates that is timed stamped at 1.4s. What would be the recommended interpolate function that i can use in Python for this? I can assume this interpolation to be linear.

I am confused by the various python interpolate functions that are available and have not tried anything yet. Would be glad to hear from any advice that the community is able to recommend.
