Removing blank spaces from a CSV file without creating a new file
<p>I have blank spaces in a csv sheet that I want to get rid of it. </p>

<p>After searching for hours I realized that this is the code for it:</p>

<pre><code>input = open('file.txt', 'wb')
output = open('new_file.txt', 'wb')
writer = csv.writer(output)
for row in csv.reader(input):
    if any(field.strip() for field in row):
        writer.writerow(row)
input.close()
output.close()  
</code></pre>

<p><strong>My question is:</strong> How do I remove the blank spaces without having to create a new file?</p>
