Usually when I write fractions I use LaTeX’s command: \frac{x^2 + 3x + 5}{2x} which is easy, neat and when rendered does an awesome job: $$ \frac{x^2 + 3x + 5}{2x} $$ Currently, though I’m designing a simple website for my math students where I’d prefer not use a math renderer (if possible). The reason being that most of the content which is published does not require extensive math notation and therefore the majority of things that I need to show doesn’t need the heavy lifting of a LaTeX engine. ...

If you’ve played with lists in Python you will reach a point where you want to copy a list to make modifications to it without changing the original list. Initially you would think the following would work: 1 2 3 4 5 6 7 >>> a_list = [1, 2, 3] >>> b_list = a_list >>> b_list.append(4) >>> print(b_list) [1, 2, 3, 4] >>> print(a_list) [1, 2, 3, 4] As you can see from the above example even though b_list was the only list which had an extra element added to it, a_list also changed! ...
