Converting dictionary value from string to float

[MortyContorty]

Hello:

I am new to Python (and a programming greenie for that matter) and I was trying to figure out how to change the "value" of my dictionary dataset from a string to a float. I imagine it is easy, but I haven't been able to figure it out.
[CODE=python]
data_list ={'11': '0.0', '10': '0.0', '13': '0.0', '12': '10.0', '15': '10.0', '14': '10.0', '17': '10.0', '16': '10.0', '19': '10.0', '18': '10.0', '20': '10.0', '1': '10.0', '3': '0.0', '2': '0.0', '5': '0.0', '4': '0.0', '7': '0.0', '6': '0.0', '9': '0.0', '8': '0.0', '21': '10.0'}[/CODE]

Any help would be appreciated!

This should do it[code=Python]newDict = dict(zip(data_l ist.keys(), [float(value) for value in data_list.value s()][/code]

Worked great! Thanks.

P.S. I must be green for naming a dictionary "data_list".... .

My friend bvdet has a great solution, but all those () and [] can be a bit daunting for a beginner. To make it look simpler, let's break it in its basic parts:[CODE=python]newDict = {} # an empty dictionary
for key, value in data_list.items (): # get the (key, value) tuples one at a time
newDict[key] = value[/CODE]
