Lookup table for standardized tails of Pearson curves.

Hello everyone,
Hope you guys are having a nice holiday.
I am trying to write a bit of code in which I want to look up the Up' and Lp' values based on the skewness and kurtosis of my data, from the following table.
I am trying to code this in Python / R / JMP, but I cant find this table in any other format but the images below.
Can anyone advice an online source like a python package/ actual file with this table that can be downloaded and used ?

Your help is greatly appreciated.
