Sum of different CSV columns in python
Why don't you :

create a columnTotal integer array (one index for each column).
read the file line by line, per line:


Split the line using the comma as separator
Convert the splitted string parts to integers
Add the value of each column to the columnTotal array's colum index.
I am quite new to Python and therefore this might seem easy but I am really stuck here.
I have a CSV file with values in a [525599 x 74] matrix. For each column of the 74 columns I would like to have the total sum of all 525599 values saved in one list.
I could not figure out the right way to iterate over each column and save the sum of each column in a list.
