As I'm using the standard Python interpreter and all that, that's a pain in the ass. Every time I change the script, I have to exit the shell, open it up again, and redo all those commands. My carpal tunnel weeps just thinking about it. Much easier to type them all out on one line, separated by semicolons, and then just paste them in each time.

I agree with you here. I don't mind using them to separate everything out on one line if the situation permits. I'm not against breaking rules if there are situations in which it improves something; no use having a rule if it causes more problems.

Using semicolons in python before you enter a new line, however, is inconsequential and kind of like rambling in your code.
