Use string to call an object and function

Question

I'm trying to take user inputs through discord and turn them into commands using imported files of my own making. The commands follow a "XX! [object] [function] command. How do I turn an inputted string into a object? Or is there someway that I can use something similar to getattr('x', 'y')?

def function():
    x = "XX! profile view"
    getattr(x.lower().split(" ")[1], x.lower().split(" ")[2])()
    return

I was hoping that would execute as profile.view(), but its giving me the error AttributeError: 'str' object has no attribute 'view'.

btw: `return` that returns nothing is useless and can be removed. — Marcin Orlowski, Jun 17 '19 at 07:34

Better to not use function string names. Correct way is to create dict which match string name with function.

def XX(*args):
    print(list(reversed(*args)))


def YY(*args):
    print(list(map(str.upper, *args)))


router = {
    "XX": XX,
    "YY": YY
}


def interpret(string):
    if any(string.startswith(key) for key in router):
        func_name = string[0: string.index("!")]
        args = string[string.index("!") + 2:].split(" ")
        router[func_name](args)


x = "YY! profile view"

interpret(x)

Perhaps you want to look into the exec() function:

mystring = r'print("Hello World")'

exec(mystring)

>>>> Hello World
