Question

I’m trying to instantiate a class object whose desired name is held in a variable that’s created elsewhere.

I can’t figure out how to make the instance of the class have the name held by the variable.

example:

class foo:
    def __init__(self):
        self.var1 = "bar"

if __name__ == "__main__":
    test = "a" # returned by another func.
    [string held by variable 'test'] = foo()
    print a.var1

Is this possible? (or even advisable…)

Answer 1

It is not advisable, since it makes it difficult to program with the variable a when you do not know its name until run-time.

You might think about using a dict instead:

data = {}
test = func()   # "a"
data[test] = foo()
