Why would I get a TypeEror?

[Harper, Gina]

Because you can't take the len() of an integer.  Try casting a as a str:
b=(1,len(str(a)))[isinstance(a,(list,tuple,dict))]

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?

Thanks,
