[python] Skip first line(field) in loop using CSV file?

Possible Duplicate: When processing CSV data, how do I ignore the first line of data?

I am using python to open CSV file. I am using formula loop but I need to skip the first row because it has header.

So far I remember was something like this but it is missing something: I wonder if someone knows the code for what I am trying to do.

for row in kidfile:
    if row.firstline = false:  # <====== Something is missing here.
        continue
    if ......

This question is related to python csv for-loop

The answer is


There are many ways to skip the first line. In addition to those said by Bakuriu, I would add:

with open(filename, 'r') as f:
    next(f)
    for line in f:

and:

with open(filename,'r') as f:
    lines = f.readlines()[1:]

csvreader.next() Return the next row of the reader’s iterable object as a list, parsed according to the current dialect.
