I think I want to use pythons built in calendar module to create an HTML calendar with data. I say I think because I’ll probably think of a better way, but right now it’s a little personal. I don’t know if this was intended to be used this way but it seems like it is a little pointless if you can’t at least making the days into a <a hrefs>.

This sets up a calendar for this month with Sunday as the first day.

import calendar
myCal = calendar.HTMLCalendar(calendar.SUNDAY)
print myCal.formatmonth(2009, 7)

it prints

<table border="0" cellpadding="0" cellspacing="0" class="month">\n<tr>
<th colspan="7" class="month">July 2009</th></tr>\n<tr><th class="sun">Sun</th>
<th class="mon">Mon</th><th class="tue">Tue</th><th class="wed">Wed</th>
<th class="thu">Thu</th><th class="fri">Fri</th><th class="sat">Sat</th></tr>\n
<tr><td class="noday">&nbsp;</td><td class="noday">&nbsp;</td>
<td class="noday">&nbsp;</td><td class="wed">1</td><td class="thu">2</td><td class="fri">3</td>
<td class="sat">4</td></tr>\n<tr><td class="sun">5</td><td class="mon">6</td><td class="tue">7</td>
<td class="wed">8</td><td class="thu">9</td><td class="fri">10</td>
<td class="sat">11</td></tr>\n<tr><td class="sun">12</td><td class="mon">13</td>
<td class="tue">14</td><td class="wed">15</td><td class="thu">16</td><td class="fri">17</td>
<td class="sat">18</td></tr>\n<tr><td class="sun">19</td><td class="mon">20</td>
<td class="tue">21</td><td class="wed">22</td><td class="thu">23</td><td class="fri">24</td>
<td class="sat">25</td></tr>\n<tr><td class="sun">26</td><td class="mon">27</td>
<td class="tue">28</td><td class="wed">29</td><td class="thu">30</td><td class="fri">31</td>
<td class="noday">&nbsp;</td></tr>\n</table>\n

I would like to insert some data into the HTMLCalendar object before it renders the html string. I just can’t figure out how.

For example

<td class="tue">28<br />[my data]</td>

    You may load html, which seems to be valid XMl into a XML tree, modify it and again output it.
    e.g. this adds <br/> cool to each Tue td node.

    import calendar
import xml.etree.ElementTree as etree

myCal = calendar.HTMLCalendar(calendar.SUNDAY)
htmlStr = myCal.formatmonth(2009, 7)
htmlStr = htmlStr.replace("&nbsp;"," ")

root = etree.fromstring(htmlStr)
for elem in root.findall("*//td"):
    if elem.get("class") != "tue":
        continue
    elem.text += "!"

    br = etree.SubElement(elem, "br")
    br.tail = "cool!"

print etree.tostring(root)

    I do not yet know why you need to generate a HTML calendar, but there are better ways of doing that depending on needs and framework you are using.
