Python tkinter binding a function with multiple parameters
arguments, python, tkinter
Solution
Here you're binding the result of `someFunction` (or trying to anyway). This fails because when python tries to get the result of `someFunction`, it calls it only passing 1 argument (`"Hello"`) when `someFunction` really expects 2 explicit arguments. You probably want something like:
self.canvas.bind('<Button-1>',lambda event: self.someFunction(event,"Hello"))
This binds a new function (which is created by `lambda` and wraps around `self.someFunction`) which passes the correct arguments.
Problem
I have a general question that I can't really find an answer to so hopefully you guys can help. I have a function that takes 3 parameters, below is an example of what I have. ``` def someFunction(self, event, string): do stuff .. self.canvas.bind("<Button-1>", self.someFunction("Hello")) ``` When I run this, I get an error saying that I passed someFunction 2 arguments instead of 3. I'm not sure why ..
