Hmmm, functions are cheap - nobody is charging you $2 for each "def"
statement you write, I presume :)
A bit more serious, if those "chunks of code" are processing its input and
returning something that you further process... they *are* functions. If
you don't want them to be publicly available, use inner functions:
def xxxfactory(x):
def f1(x):
...
def f2(x):
...
def f3(x):
...
for f in f1,f2,f3:
try:
return f(x)
... same as above...
