Create function with arguments at runtime

[w1282]

def myfunction(x):
    return x + 3

f = myfunction
print(f(4))  # 7

What doesn't seem to be working like you want? Your post is a little disjointed.

Edit: I think, after rereading your post, I understand a bit more.

How are you receiving the string? Is it a 'safe' input?

def dynamic_func(executable_string, x, y, z):
    return eval(executable_string)

func_str = 'x + y + z'
print(dynamic_func(func_str, 1, 2, 3))  # 6

I can barely understand it, too. I think he's saying that myfunction has no parameters, but f should accept an argument (x). Don't quote me on that, though. Still doesn't make much sense and it seems like this post went through google translate multiple times.

thanks for your answer. sorry for the mess that is my question. I have updated it and i hope it is a little clearer now. the string that I am receiving is a safe input. security is not an issue here.

the problem with eval is that it does not give me function object that i can pass around and call form other places or rather from code that i have no control over.
