python create variables from dictionary entries

Question

I would love to do something like this:

rates={'r1':10, 'r2':20}

and then do some cool command (what is it???) to end up with variables in my namespace

>>>r1 
10

>>>r2
20

Is this a dumb idea?

You are generally better sticking with the dictionary than trying to play with dynamic variables — jonrsharpe

Defining a dictionary and injecting it into the globals namespace is actually more typing than just doing r1=10;r2=20 etc — Matthew Trevor

You can just do:

globals().update(rates)

Anyway, it's usually a bad practice.

This won't work (unless locals() is globals()). Well, in some implementations of Python it might work, but at least in CPython it won't.

@WolframH: You're right, edited with globals(), that should be fine.
