How do I find a preexisting variable with a list of strings in Python?
I have a list of strings, such as:
letters = ["C", "A", "M", "P"]
and a set of preexisting variables, such as:
C = pygame.image.load("resources/menu icons/imgC.png")
A = pygame.image.load("resources/menu icons/imgA.png")
M = pygame.image.load("resources/menu icons/imgM.png")
P = pygame.image.load("resources/menu icons/imgP.png")
I am looking for a command such as:
surface.blit(letters[0])
to display the image on the screen. Can anyone help?
I'd probably go for a dictionary.
d = {
'C': pygame.image.load("resources/menu icons/imgC.png"),
'A': pygame.image.load("resources/menu icons/imgA.png"),
'M': pygame.image.load("resources/menu icons/imgM.png"),
'P': pygame.image.load("resources/menu icons/imgP.png")
}
Then you can look stuff up that way
d['A']
Or
d[letters[1]]
Cyber's method has the advantage of keeping your namespace more organized, but it's also nice to know about globals , with which you can do this:
surface.blit(globals()[letters[0]])
(assuming C
, A
, M
, P
are defined in the global namespace. If they are local variables, you could use vars() instead of globals()
.)
