Answer 1

with open("test.csv",'r') as f:
    with open("updated_test.csv",'w') as f1:
        next(f) # skip header line
        for line in f:
            f1.write(line)

Answer 2

For anyone else caught up this error:

AttributeError: '_io.TextIOWrapper' object has no attribute 'next' python

In Python3 a text file object doesn't have a next() function. So you can't call f.next().

Instead you should use f.readline() as specified in this answer.

Or you can use the built-in next(f) which @vrjr mentioned in the comment, and is shown in this answer.

Answer 3

This is what I do when I want to skip reading the first line of a CSV.

All that has to be done is call the next() function of the CSV object, in this case - read, and then the pointer to the reader will be on the next line.

import csv

try:
    read = csv.reader(f)
    read.next()     # Skip the first 'title' row.
    for r in read:
        # Do something
finally:
    # Close files and exit cleanly
    f.close()

Hope this is pretty clean an simple for your purposes!
