Question

I am writing a python script to read a file which consists of three columns separated by commas, create a tuple of each line, and make a list of these tuples. With the following script I achieve what I want; I was just wondering whether there is an easier / more elegant approach than writing each of the following steps in a seperate line.

import sys
fin=open(sys.argv[1],'r') 

list  = []

for line1 in fin:
        line2 = line1[:-1]
        line3 = line2.split(',')
        line4 = tuple(line3)
        list.append(line4)
print(list)

Thank you for your answers.

Python comes with batteries included! If you need to read csv files, just use the csv module:

import sys, csv

with open(sys.argv[1]) as f:
    lst = list(csv.reader(f))

Note that this creates a list of lists, if you want tuples for some reason, then

with open(sys.argv[1]) as f:
    lst = [tuple(row) for row in csv.reader(f)]
