Wouldn't it be easiest just to keep the variables in a dictionary or
something, and then refer to them by key?
funcs = {}
for (variable, value) in assignment_list:
funcs[variable] = func(arg=value, *args)
print funcs['var1']
There doesn't seem to be any benefit to having things in the python
namespace when for your purposes a dictionary would work very cleanly.
