Python read CSV file, and write to another skipping columns
<p>I have CSV input file with 18 columns
I need to create new CSV file with all columns from input except column 4 and 5</p>

<p>My function now looks like</p>

<pre><code>def modify_csv_report(input_csv, output_csv):
    begin = 0
    end = 3

    with open(input_csv, "r") as file_in:
        with open(output_csv, "w") as file_out:
            writer = csv.writer(file_out)
            for row in csv.reader(file_in):
                writer.writerow(row[begin:end])
    return output_csv
</code></pre>

<p>So it reads and writes columns number 0 - 3, but i don't know how skip column 4,5 and continue from there</p>

<p>This is what you want:</p>

<pre><code>import csv


def remove_csv_columns(input_csv, output_csv, exclude_column_indices):
    with open(input_csv) as file_in, open(output_csv, 'w') as file_out:
        reader = csv.reader(file_in)
        writer = csv.writer(file_out)
        writer.writerows(
            [col for idx, col in enumerate(row)
             if idx not in exclude_column_indices]
            for row in reader)

remove_csv_columns('in.csv', 'out.csv', (3, 4))
</code></pre>

python csv
