In the context of Abstract Algebra, groups are used to study the symmetries that exist for anobject (defined as a set X). The group can define an action on the given object, for example the rotation of a square centered on the origin. One important characteristic of our group, is that it contains an identity element. In our example, rotating the square by zero degrees gives us a symmetry of the square. The group should also have an inverse element. Rotating the square by 90 degrees leads to a symmetry. rotating the square back by -90 degrees is also a symmetry and our square is back to the original orientation. This illustratess the inverse property of a group. The final important property of a group is associativity.

Hi there friend
So I wrote a python script that converts the text file I am writing on currently into the html content that will appear and make the site look pretty. I haven't really used python in a couple years so I've been flipping through Al Sweigart's Automate the Boring Stuff with Python. My idea was to open this file and write the contents into a python string using a special character as a delimiter between posts. Then a for loop iterates through the entries, again uses a delimiter to seperate the title, date, and body and wraps each with the markup tags as needed.
Ok this is the first post in my undergrad programming handbook. Various tasks* have popped through my space while working towards my degree that I kept coming back to; sometimes I had to google how to do those tasks again and again. Or maybe there was a concept that I thought especially important and deserved to be memorialized on my grand, little programming blog site. *realistically it was having to indent the start of n lines in Vim that did it
