Hi guys, i got into another situation i was told not to use csv library and currently my code is :

f = open('friends.csv', 'rU')
for row in f:
        
        print [row for (row) in f]

output :
['John Cleese,Ministry of Silly Walks,5555421,27-Oct\n', 'Stacy Kisha,Ministry of Man Power,1234567,17-Jan\n']

i need it to become :
[('John Cleese', 'Ministry of Silly Walks', '5555421', '27-Oct'), ('Stacy Kisha', 'Ministry of Man Power', '1234567', '17-Jan')]

guide me please
