How to convert a Python tuple to dictionary with variable name as key?

Question

I would like tuple (foo, bar) where

 foo = 1
 bar = 2

be converted to,

foo_dict = {'foo' : foo, 'bar' : bar}

Is there an easy way to do it?

Update:

I see that my original post is quite misleading. So, considering foo and bar are local variables within a function scope. I'd like them to be saved to a global dictionary where the keys are their variable names.

Re-update: Thanks everyone for the attention. I was using ipywidgets.interact to tune some parameters (passed as value), however I would like to save them globally, say in a dictionary. That's why the question comes in. Maybe for downvoters there may seem pointless to do such conversion, but do please share some hints for solve my needs pythonically.

A tuple contains values, not variables. There is absolutely no connection between those values and the variables that held them; indeed, the value might never have been held in a variable at all, or might have been held by multiple variables. — jasonharper

@jasonharper I see, forgiving tuple, how could we do so for several variables then? If we have a dozen? — MeadowMuffins

Actually I think this can be done, I just have to put the pieces together. I'm currently testing. — roganjosh

The required function call is

def func(**kwargs):
    for key in kwargs.keys():
        globals()[key]=kwargs[key]
    return kwargs

foo_dict = func(foo = 1, bar = 2)
print(foo_dict)
print(foo)
print(bar)

#{'bar': 2, 'foo': 1}
#56

Yep, I've just got this far too. Problem solved. I guess I posted a bad question.
