python - Pythonic switching using functions inside a class -

i attempting utilize dict command function selection within class, however, next typeerror:

typeerror: a() missing 1 required positional argument: 'self'

example code:

class tt: def __init__(self): pass def a(self): print("a") def b(self): print("b") def c(self): print("c") a_diction={ '0' : a, '1' : b, '2' : c } def ad(self,data): self.a_diction[data]()

how should build switch in ad provide self both a_diction , called method a, b , c?

the error message indicates you're missing argument. suggest adding argument.

self.a_diction[data](self)
