I have a question about where variables are exposed in python.
You're looking for scoping rules -- see for example
http://stackoverflow.com/questions/291978/short-description-of-python-scoping-rules
where they get into some detail, but the short and older version is 1)
search in local-global-builtin, and 2) if you assign to it in a scope,
it's local to that scope.
So, blah and foo below are visible in all the functions except any that
specifically assign to blah or foo.
HTH,
Emile
I have a monolothic script with a number of functions defined, can those
functions share variables? can I instantiate them outside the function of where
they are needed? do they need to be wrapped in quotes, ever? For example:
blah = 123
foo = 'somestring'
def function(foo):
code that needs foo
anotherfunction(blah)
def anotherfunction(blah):
code that needs blah
code that uses foo
....how about this:
def function(blah, foo):
anotherfunc(blah)
anotherfunc(foo)
...what about my python being called from some parent script (something OTHER
than python) that instantiates blah and foo FOR me? Can I just plug those into
my code like I would normally? I guess this is more about HOW and WHERE I can
make variables available for use.
