[Tutor] ignoring certain lines while reading through CSV

[Abhishek Pratap]

Hi Joel

Here is a sample

['1', 'AAAAAAA', '4344', '0.001505'] : want to keep this one

['#', 'AAAAAAA', '4344', '0.001505'] : and throw this one


You are right I am checking after parsing. I dint find an option in
csv.reader to ignore lines.
