How to sum the data from multiple columns ?

0 votes
Hello,

I begin by saying that I do not know anything about programming.

Here is my problem :

I have 77 data (numbers) files with three columns each. The first column is the same in all files. I would like to create a new two-column file with the following requirements:

- The first column should be the same as that of my input 77 files;

- The second column should be the result of the sum of the data of the second column of all my input 77 files.

Can you help me to do it with the Python language ?

Thank you.
