The nice thing about Python is you don't have to build things from scratch,
and I imagine most people would discourage on account of it being a waste of
time, other then education value.
But the "best practice" in my humble opinion would be to use the built in
len function. If what you are after is to see how often 1e3 comes up in your
list, then you would use list.count('1e3').
In general, its best to use the python built ins.
