I have a dictionary in Python (uglyDict) that has some really un-cool key names. I would like to rename them based on values from another dictionary (keyMapping). Here's an example of the dictionaries:

uglyDict = {
    "Ship To - Name": "Noah",
    "Ship To - Location": "my crib"
}

keyMapping = {
    "Ship To - Name": "ShipToCompany",
    "Ship To - Location": "ShipLocation"
}

Here is my code so far to rename uglyDict's keys:

prettyDict = {}
for mkey, mval in keyMapping.items():
    for ukey in uglyDict.keys():
        if mkey == ukey:
            prettyDict[mval] = uglyDict[mkey]

print(prettyDict)

The code works as desired, and prints the dictionary with renamed keys as shown below:

{'ShipToCompany': 'Noah', 'ShipLocation': 'my crib'}

My question is, is there any more efficient/more Pythonic way to do this? Preferably one where I don't have to loop over the keys of both dictionaries. I am using this code with much larger dictionaries and performance is needed.
Any insight is welcome!
