Find specific,closest point between two others

I have array/dict (whatever) with x,y of points:

1000 - 460
2000 - 470
3000 - 520
4000 - 520
5000 - 620
6000 - 660
7000 - 730
8000 - 700
9000 - 650
10000 - 600
11000 - 510
12000 - 430
13000 - 380
14000 - 330
15000 - 280

on chart they looks like this: enter image description here

Could you help me with finding another point, to be more specific, find Y of point when for example X = 8136? Is there any way to estimate this to know the x, y of points between which it is located?

There is a "technique" called interpolation; it is an estimation based on your data set. There are different kinds of interpolations, where linear interpolation is the simplest one but produces the biggest error; to make it in python you could use scipy.interpolate() from the scipy library or dataframe.interpolate() from pandas library, please refer to the links below for more information:
