Using string literals as keys

Hi, so if I have a string returned from the input() function how can I make that string (or part of the string) a key in a dictionary?


ex:

b = {}

a = input ("Your text here: ")

how would I make the value of a the key in b?

thanks

Strings are immutable. Thus they have a hash that won't change. Therefor they can be dictionary keys.

strings, tuples, frozensets, and um, numbers can be keys. There may be a few other types that can also be used for keys, possibly None, type(object) .

The python3 value returned from input() can be directly used as a dictionary key.
