How to name class instances after an iterable keys?

I'd like to create instances of classes getting their names from list values or dictionaries keys or values. Basically what I'd like to do is:

iter = ['foo', 'bar']
for a in iter:
    a = Cls()

and get foo and bar instances of Cls() class instead of having instance referenced by a updated at each loop.

Thanks in advance.

You could use dynamic code evaluation.

inst1 = eval("foo()")
inst2 = eval(a + "()")
inst3 = eval(a)()

Maybe with a dictionnary : 

iter = ['foo', 'bar']
result = {}
for a in iter:
    result[a] = Cls()

And in result you'll have { 'foo' : instance_of_Cls, 'bar' : instance_of_Cls}
