What type of *data* is the name of a list/tuple/dict, etc?

[deanhystad]

For something like this I would use a dictionary or database depending on if the device list is fixed or fluid. This is an example of using a dictionary.

devices = {
    "0.1K1A":[1.942952*10**-3, 2.989769*10**-4, 3.504383*10**-7],
    "0.3K1A":[1.627660*10**-3, 2.933316*10**-4, 2.870016*10**-7],
    "1K2A"  :[1.373168*10**-3, 2.772261*10**-4, 1.997412*10**-7],
    "1K7A"  :[1.446059*10**-3, 2.683626*10**-4, 1.643561*10**-7],
    "2K3A"  :[1.498872*10**-3, 2.379047*10**-4, 1.066953*10**-7],
    "2.2K3A":[1.471388*10**-3, 2.376138*10**-4, 1.051058*10**-7],
    "3K3A"  :[1.405027*10**-3, 2.369386*10**-4, 1.012660*10**-7],
    "5K3A"  :[1.287450*10**-3, 2.357394*10**-4, 9.505200*10**-8],
    "10K3A" :[1.129241*10**-3, 2.341077*10**-4, 8.775468*10**-8],
    "10K4A" :[1.028444*10**-3, 2.392435*10**-4, 1.562216*10**-7],
    "30K5A" :[9.331754*10**-4, 2.213978*10**-4, 1.263817*10**-7],
    "30K6A" :[1.068981*10**-3, 2.120700*10**-4, 9.019537*10**-8],
    "50K6A" :[9.657154*10**-4, 2.106840*10**-4, 8.585481*10**-8],
    "100K6A":[8.271111*10**-4, 2.088020*10**-4, 8.059200*10**-8],
    "1M9A"  :[7.402387*10**-4, 1.760865*10**-4, 6.865999*10**-8]
}

def select_device():
    while True:
        for index, name in enumerate(devices):
            print(f'{index+1:2d}: {name}')
        name = input('Enter device name or number : ').upper()

        if not name in devices:
            try:
                name = list(devices.keys())[int(name)]
            except:
                pass

        dev = devices.get(name, None)
        if dev is not None:
            return name, dev

print(select_device())
