    <p>This is my first python <strong>(2.4)</strong> program and I could use your help. I have a csv file</p> <pre><code>HOST, PATH server1, /path/to/file1.py server2, /path/to/file2.py server3, /path/to/file3.py </code></pre> <p>That executes a command to each PATH on column 2/row[1]</p> <p>In the output of the command I search for text and append them to new columns.</p> <p>Example command output:</p> <pre><code>Command: python /path/to/file1.py Output: server1 (NTFS) Reply:Yes </code></pre> <p>I would like make my new csv file like:</p> <pre><code>HOST, PATH, PLATFORM, REPLY server1, /path/to/file1.py, Windows, Yes server2, /path/to/file2.py, Linux, Yes server3, /path/to/file3.py, BSD, No </code></pre> <p>I havnt yet got it to work with reading the same output line and appending two columns with different results. I have tried closing the writer and opening a new one within the same reader with no joy. I have tried indenting with no luck. The closest I have gotten is having it accurately search for both strings but it only writes to one column.</p> <p>I have also tried first searching for the os platform and writing the changes to a new file Then, opening the new file to write another row</p> <p>Of course I could force this to work by running the commands again and searching separately, but thats redundant and unnecessary.</p> <pre><code>import datetime import csv import os, time from stat import * # ST_SIZE etc from subprocess import Popen, PIPE, STDOUT # Set Date now = datetime.datetime.now() today = now.strftime("%m-%d-%Y") # Files filename = "my_list.csv" results = "results/results_" + today + ".csv" # Eg. results_04-14-2012.csv # Commands command = "python" SP = " " incsv = open(filename, 'rb') try: reader = csv.reader(incsv) outcsv = open(results, 'w') try: writer = csv.writer(outcsv) for row in reader: p = Popen(command + SP + row[1], shell=True, stdin=PIPE, stdout=PIPE, stderr=PIPE) stdout, empty = p.communicate() print 'Command: %s\nOutput: %s\n' % (command + SP + row[1], stdout) if not stdout: writer.writerow(row + ['PLATFORM']) # Create header for new column when first line is empty on stdout elif 'BSD' in stdout: writer.writerow(row + ['BSD']) elif 'Linux' in stdout or 'swap' in stdout or 'LLVM' in stdout or 'EBR' in stdout: writer.writerow(row + ['Linux']) elif 'NTFS' in stdout: writer.writerow(row + ['Windows']) else: writer.writerow(row + ['Error Scanning']) reply = open(results, 'w') try: writer = csv.writer(platform) for row in reader: if not stdout: writer.writerow(row + ['REPLY']) # Create header for new column when first line is empty on stdout elif 'Reply:Yes' in stdout: writer.writerow(row + ['Yes']) elif 'Reply:No' in stdout : writer.writerow(row + ['No']) else: writer.writerow(row + ['Error']) finally: reply.close() finally: outcsv.close() finally: incsv.close() </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
