Lower Case L Variables Spotted
Arrrgh!
You should NEVER use the lower-case L as a variable name. Ever. Especially if you’re going to have it in proximity to a 1 (which is a one, a fact that I have to call out because it looks like the l, which is an L). Ever. Never ever ever. Even in Python, which is one of the most readable languages in the world when it’s done correctly.
2 def perm(l): 3 sz = len(l) 4 if sz < = 1: 5 return [l] 6 return [p[:i]+[l[0]]+p[i:] for i in xrange(sz) for p in perm(l[1:])]
The algorithm/snippet is okay, other than the choice of variable names, with is quite dreadful all the way through.
URL withheld to protect the butthead.
Unless the purpose of the variable is to represent a “line,” in which case it’s a really good mnemonic because it looks like a line. What’s not to love?

Ooo, maybe we can mix 1, l, |, and I liberally in code. It would be a language like BF in too many ways. Maybe call it the “tall men” language. A snippet of code:
|1!!l||1|I*ll1.l1|.I1l!|
