I guess you meant:  a, b, c = row  
?

Also you will want to do appropriate type conversions up front.
eg if the first field is string the second field is int and the third a float

something like
  
a,b,c = row[0], int(row[1]), float(row[2])

More generally as Terry said csv is not necessarily a appropriate standard
(because there is no standard!!)
If inputting outputting to/from a spreadsheet is required thats ok.

Else there are dozens of others.
My favorite is yml
Json is close enough and getting more traction nowadays
Then of course there's XML which everyone loves to hate -- for reasons similar
to csv it may be required
