A particularly mysterious, unreadable and useless way to "do it in one":

i = [ j for j in j, j+1 ][0]

Generally, I find that abusing list comprehensions is the easiest way
to produce obfuscated Python.  The specific "feature" of LCs that makes
them so suitable for obfuscation is their ability to rebind variables
in their for clauses.
