How to make columns into lists for .csv (excel) with Python?

Asked by chk8n (106points) February 15th, 2011

What I mean by column is when you have:

Student Grade GPA
Max B 3.2
Angel A 3.5
Sonny C 2.1

So column 1, I want: Student Max Angel Sonny
Column 2 I want: Grades B A C
So on….

That is what I have on .csv file.

The code I would need to use is:

StudFile = open(“grades.csv”, “r”)

How to make it read so that I only show the Name of the student AND the GPA only?

Thank you for the help!

data = open(“grades.csv”,“r”).readlines()
for line in data:
[t]items = line.split()
[t]print items[0], items[2]

note that Fluther strips the required tabbing from the program, replace [t] with a real tab. Should add catching exceptions where the file doesn’t exist, or there is not 3 entries on a line. Also relies that the file uses whitespace, not commas to delimit columns. Should really close the file in the program and not leave the OS to sort it out.

For more advanced CSV parsing, use the csv module.
