I want to use input() to call one of three possible lists (a, b, or c) and then run functions on that chosen list.
At one point I had this working, so not sure what I changed. I think it's an issue with the way it's declared.
a = ["1","2","3"]
b = ["4","5","6"]
c = ["7","8","9"]
choice = input("Choose a, b, or c")
print choice[0]
some_function(choice)
If input is a I want to get "1" as the output.
Put your lists in a dict instead of 3 separate variables.
choices = {
'a': ["1","2","3"],
'b': ["4","5","6"],
'c': ["7","8","9"],
}
choice = input("Choose a, b, or c")
print(choices[choice])
choices.get(choice, None) would prevent exceptions for an invalid input (though its arguable wether exceptions should be ignored here or not)
Just use a dictionary. Here is how that would work.
dictionary = {"a": ["1", "2", "3"]} choice = input("Choose a, b, or c: ")
print(dictionary[choice][0])
Dictionary uses a key and value. Your key here would be the string "a" (Keys are immutable) and value would be the corresponding array. Dictionary[key] gives you a value and Dictionary[key][0] is basically value[0]. So you are simply indexing the list.
You can use one dictionary for all declared lists.
dictionary = {"a": ["1", "2", "3"], "b": ["5", "6", "7"]} and onwards....
Plus they are more efficient than lists.
