Why isn't my turtle keybinding responding?

Question

I am in the process of modulating my code for a game that I wrote. When I modulated the player class, I add all the additional parameters/arguments so it can be separated. I kept the keybinding within the the main game module.

The keybinding code look like this

turtle.listen()
a=turtle.onkey(player.go_left(walls), "Left")
b=turtle.onkey(player.go_right(walls), "Right")
c=turtle.onkey(player.go_up(walls), "Up")
d=turtle.onkey(player.go_down(walls), "Down")
e=turtle.onkey(player.headright(missile,lives), "d")
f=turtle.onkey(player.headleft(missile,lives), "a")
g=turtle.onkey(player.headdown(missile,lives),"s")
h=turtle.onkey(player.headup(missile,lives),"w")
i=turtle.onkey(player.headright(missile,lives),"D")
j=turtle.onkey(player.headleft(missile,lives), "A")
k=turtle.onkey(player.headdown(missile,lives),"S")
l=turtle.onkey(player.headup(missile,lives),"W")
o=turtle.onkey(player.drink(info),"space")
m=turtle.onkey(player.fireball(missile2,info,lives),"z")
n=turtle.onkey(player.fireball(missile2,info,lives),"Z")

The game is running without error but the keys aren't responding to the action.

You can find the code in

The keybinding code is in game(mod version)

All functions are within 'player.py'

Any help would be great.

Answer 1

The onkey function only allows a function with no arguments hence it is not possible to use functions with arguments hence why it doesn't work.

https://docs.python.org/2/library/turtle.html#turtle.onkey

But... If you use

turtle.onkey((lambda:player.go_left(walls)), "Left")

it will work because you are creating a function within a function which will express the output as if it had no arguments.
