TypeError: get() missing 1 required positional argument: 'self'

Question

I'm that guy who had an problem with a calculator.thanks to Joran Beasley I've got my problem better.But now i have this problem.

Code:a part was

intery.config(intery+intery2)
print(su)

now its:

def su():
int(Entery.get())

New Error:

TypeError: get() missing 1 required positional argument: 'self'

I'll be happy if Mr.Beasley Will help me.

Answer 1

It looks like you're calling a method ( get ) on a class ( Entery ). That's not working because the method expects to be called on an instance of the class, rather than the class itself.

I don't know enough about your program to guess where you should be creating the instance, but here's the general idea:

# somewhere in your code:
entery = Entery() # maybe pass some args?

# later
def su():
    return int(entery.get()) # call on the saved instance

I'd added a return to your function, as otherwise you'd be converting the return value of get() to an int and then immediately throwing that integer away. I suppose you might choose to do something else with it, but again, I don't know enough about your code to guess.
