For this code snip:
a=3 .... b=(1,len(a))[isinstance(a,(list,tuple,dict))]
Why would I get a TypeError from the len function?
the problem is, that (1,len(a)) is evaluated, neither what type a actually has
(python has no builtin lazy evaluation like ML). You have to do it this way
instead:
a=3 ... b = isinstance(a,(list,tuple,dict)) and len(a) or 1
