Python3: How to dynamically reference the name of a dictionary

Question

I'm still learning python and I'd appreciate any direction for the problem that I'm having.

I have menu options set up in two separate dictionaries in the following structure

menu0000 = {
    1 : {
        "label" : "Library"
    },

    2 : {
        "label" : "Listen Now"
    }
}

menu0001 = {
    1 : {
        "label" : "Shuffle Songs"
    },

    2 : {
        "label" : "Playlists"
    }

}

A variable has been set up to keep track of the name of which dictionary I am currently accessing

menuName = "menu0000"

Without hard-coding the name, I'd like to access the dictionary dynamically based on the contents of the menuName variable, eg:

for key in menuName:
    print(menuName[key]["label"])

How do I call menuName in a way that invokes a dictionary? The idea is to update menuName at a later stage so that I can access different dictionaries.
