Question

I need to create a function which can:

1. Inspect input arguments and get the number of inputs and their values
2. Create a loop, and add string ‘_in’ after each input name
3. Make the new inputs global
4. Assign new inputs with old values

I tried to use inspect.getargspec() but it seems like this should be called outside the function. So any suggestions?

Here is the pseudo code:
Define this function:

def set_global(a1, a2, a3, .... an):
    #the number of arguments is not fixed and we need to detect that
    for old_input in total input:
         new_input_name=str(old_input.name)+'_in'
         global new_input_name 
         new_input_name = old_input.value

I really think you’re looking for the globals function.

a = 1
globals()['a'] = 2
print a  #2
globals()['a_in'] = 2
print a_in  #2

You could put this in a function:

def do_something_with_globals(**kwargs):
    for k,v in kwargs.items():
        globals()[k+'_in'] = v

Which could be called like this:

a = 1
b = 2
do_something_with_globals(a=a,b=b)
print a_in
print b_in

But, honestly, I really don’t think this is a good idea…
