Here's a simple-minded example:
def dumbfunc(xs):

print x
This function works fine if xs is a list of floats, but not if it is
single
float. It can be made to work as follows:
def dumbfunc(xs):
if isinstance(xs,(int,float,complex)): xs= [xs]
for x in xs:
print x
Having to put such extra logic into practically every function is one of
the
annoying things about Python.
If you persist in treating <language 1> as if it was <language 2>, then
your code will always be ugly, and often buggy. Unless we're talking
natural languages, in which case Yoda-like you will sound.
Fundamentally, your problem is your assertion that it is reasonable to
allow users to treat a single object as if it were wrapped in a list.
In Python, it is not reasonable, for the reasons that you are spending
so much time complaining about.
