Read specific columns in csv using python

Question

I have a csv file that look like this:

+-----+-----+-----+-----+-----+-----+-----+-----+
| AAA | bbb | ccc | DDD | eee | FFF | GGG | hhh |
+-----+-----+-----+-----+---         


        

Answer 1

If your files and requirements are relatively simple and set, then once you know the desired columns, I would likely use split() to divide each data line into a list of column entries:

alist = aline.split('|')

I would then use the desired column indices to get the column entries from the list, process each with strip() to remove the whitespace, convert it to the desired format (it looks like your data has integer values), and create the tuples.

As I said, I am assuming that your requirements are relatively fixed. The more complicated or the more they are likely to change, the more likely that it will be worth your time to pick up and use a library made for manipulating this type of data.
