    <p>Here's how to get the name of the next month, given the name of the current month:</p> <pre><code>import calendar nextmonth = calendar.month_name[1:][(calendar.month_name[1:].index(month) + 1) % 12] </code></pre> <p>And here's that same logic applied to your script, with a few other improvements :) Run this script as "<code>./myscript.py somemonth someyear</code>". It'll output a CSV file named <code>nextmonth year MRG.csv</code>, even taking into account localization and wrapping the year properly.</p> <pre><code>import pandas as pd import calendar import sys if len(sys.argv) != 3: print "Usage: {0} &lt;month&gt; &lt;year&gt;".format(sys.argv[0]) month, year = sys.argv[1:] if not month in calendar.month_name: print "Invalid month! Month must be one of:{0}".format(str(calendar.month_name)) if not year.isdigit(): print "Invalid year! Year must be a number." nextmonth = calendar.month_name[1:][(calendar.month_name[1:].index(month) + 1) % 12] df1 = pd.read_csv("data csv 1\{0} {1} 1 UUedit1.csv".format(month, year), delimiter = ",") df2 = pd.read_csv("data csv 1\{0} {1} 2 UUedit2.csv".format(month, year), delimiter = ",") merged = df1.merge(df2, on="Unique Element") delcols = "Element_y", "number_y", "date_y", "title_y", "name_y" for delcol in delcols: del merged[delcol] merged.rename(columns={"name_x": "name", "rdate_x": "date", "title_x": "title", "number_x": "number", "Element_x": "Element"}, inplace = True) merged = merged.sort("Element").reset_index(drop=True) merged = merged.sort("date").reset_index(drop=True) if month == calendar.month_name[-1]: year = str(int(year + 1)) merged.to_csv("{0} {1} MRG.csv".format(nextmonth, year), index=False, sep = ",") </code></pre> <p>If you don't need the next-month feature (sounds like you actually don't), take out these two lines:</p> <pre><code>nextmonth = calendar.month_name[1:][(calendar.month_name[1:].index(month) + 1) % 12] [...] if month == calendar.month_name[-1]: year = str(int(year + 1)) </code></pre> <p>and replace the last line with:</p> <pre><code>merged.to_csv("{0} {1} MRG.csv".format(month, year), index=False, sep = ",") </code></pre>

    3. COYou're welcome! If you really want to thank me, look up the functions I'm using there and figure out how each of those things is implemented, play around with them and apply it in your own code :)

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
