Change values of a column in CSV file using python
<p>I am new to python and just need a small help.</p>

<p>We have a Pipe delimited CSV file which looks like this </p>

<pre><code>DATE|20160101
ID | Name | Address | City | State | Zip   | Phone | OPEID  | IPEDS |
10 | A... | 210 W.. | Mo.. | AL... | '31.. | 334.. | '01023 | 10063 |
20 | B... | 240 N.. | Ne.. | Ut... | '21.. | 335.. | '01024 | 10064 |
</code></pre>

<p>Every value of Zip and OPEID columns has apostrophes in the beginning </p>

<p>So we wish to create a new CSV file where apostrophes are removed from each value of these 2 columns.</p>

<p>The new file should then look like this:</p>

<pre><code>DATE|20160101
ID | Name | Address | City | State | Zip  | Phone | OPEID | IPEDS |
10 | A... | 210 W.. | Mo.. | AL... | 31.. | 334.. | 01023 | 10063 |
20 | B... | 240 N.. | Ne.. | Ut... | 21.. | 335.. | 01024 | 10064 |
</code></pre>

<p>This code works for copying data without removing apostrophes</p>

<pre><code>import os
import csv

file1 = "D:\CSV\File1.csv"
with open(file1, 'rb') as csvfile:

         reader = csv.reader(csvfile, delimiter = '|')

         path = "D:/CSV/New"
         if not os.path.exists(path):
             os.makedirs(path)

         writer = csv.writer(open(path+"File2"+".csv", 'wb'), delimiter = '|')

         for row in reader:
             writer.writerow(row)

csvfile.close()
</code></pre>

<p>To remove apostrophes you can use the <a href="https://docs.python.org/2/library/string.html" rel="nofollow">replace function</a>, you just need to get the content of every cell one by one, and replace the apostrophes with:</p>

<pre><code>new = old.replace("'", "")
</code></pre>

<p>More simply, open your csv file with any file editor and search and replace for "'".</p>
