How to find the minimum (maximum) value of a table column and specify the value of the cell corresponding to this row in another column?

Question

Python

Hello!

The question is related to data analysis in python with pandas, matplotlib.pyplot and numpy.

I took the following table:
https://stats.oecd.org/Index.aspx?DataSetCode=SKIL...
Deleted columns and rows that were not of interest from it. And then I want to find the minimum (maximum) value of a table column and indicate the value of the cell corresponding to this row in another column. That is, find in which Country a certain Skill has a minimum (maximum) Value.
I was only able to find the minimum (maximum) Value for each Skills (see table titled "Failed ;(" at https://colab.research.google.com/drive/1VyBF_vmAT... ).
