Sometimes it's hard to tell the difference.

for instance one smart and experienced guy I knew said if there was an error, your program should just fail instead of giving a ton of messages and recovering.

and if you're just throwing code together, that might be what you do.

on the other end of the scale, a well written "second pass through everything with cleanup" might have tastefully written code, a few relevant comments and consistency.

and then I've seen a lot of code that appears to look like that, but is copy/paste garbage. (sort of the coding equivalent of a wordpress theme)
