Changing the structure of a function with if statement Python

Question

There is the function a could either be in the form of client.LinearKline.LinearKline_get() or in the form of client.Kline.Kline_get(). How could I make a and b modular so that both options could work the function below does not really work.

if choice ==1:
    a= LinearKline
    b= LinearKline_get
else:
    a= Kline
    b= Kline_get

client.a.b()

you can also use getattr for this.

if choice == 1:
    a = "LinearKline"
    b = "LinearKline_get"
else:
    a = "Kline"
    b = "Kline_get"

getattr(getattr(client, a), b)()

actually instead of a and b could I write it as a="LinearKline.LinearKline_get"?

@tonyselcuk why don't you try it yourself and tell us!

I tried to do getattr(client, a)() but its giving me an error

maybe because a might not be a function.

a is a and b combined your function works I am just trying to make it simpler.

If you have access to the client variable you can directly pick the function you need to call:

if choice == 1:
    f = client.LinearKline.LinearKline_get
else:
    f = Kline.Kline_get

f()
