为什么我的 Python tkinter 复选框没有出现？

Question

so I tried putting a checkbox into my tkinter window with this code:

def a():
    if checkbutton.get():
        print("Checkbox is chosen")
    else:
        print("Checkbox ist not chosen")


checkbutton = IntVar(Checkbutton)
checkbutton =
Checkbutton(self=checkbutton,master=root,text="Pyhon3",variable=checkbutton,command=a)
checkbutton.pack()

and That generated this error:

File "C:\Users\ulric\Desktop\Tkinter.py", line 63, in <module>
    checkbutton = IntVar(Checkbutton)
TypeError: _root() missing 1 required positional argument: 'self'

I don't know what to pass in for "self"... Can someone help me please?

IntVar() does not take any parameters which is what caused the problem. Also either change the variable or check button name or the program will throw another error saying the checkbutton attribute does not have a get() method. I added an "n" to the checkbutton object but you can change this if you wish.

def a():
    if checkbutton.get():
        print("Checkbox is chosen")
    else:
        print("Checkbox ist not chosen")


checkbutton = IntVar()
checkbuttonn = Checkbutton(root,text="Pyhon3",variable=checkbutton,command=a)
checkbuttonn.pack()

root.mainloop()
