Can't import tkinter, tkinter is not defined - it seems not to be the usual problem

Python3 gives me this or other errors, whatever method i use to import tkinter.

I searched online a solution to my problem but none worked. I am running the latest version of Ubuntu. 

#!/usr/bin/env python3
from tkinter import *
def main():
    main_window = tkinter.Tk()
    main_window.title("free communism here")
    click_function = print("WEWE")
    communism_button = tkinter.button(text = "click for free communism", command = click_function, height = 40, width = 120)
    communism_button.pack()
    tkinter.mainloop()
main()

The result is: 

Traceback (most recent call last):
  File "communism button.py", line 10, in <module>
    main()
  File "communism button.py", line 4, in main
    main_window = tkinter.Tk()
NameError: name 'tkinter' is not defined.

I can't figure out why the program doesn't work. It should display a button and if you press it, it should display "WEWE". Sorry for my probably bad english.

The problem lies in the fact that you use from tkinter import * and then use the button function as tkinter.Button. When you use from xxx import * you don't use the 'xxx' package name anymore (so just Button()). Otherwise just use import tkinter, after which you do use tkinter.Button().

I personally prefer import xxx for larger scripts, because it's more clear where a method comes from.

Besides that, your code still has another problem with your 'click_function'. You should make that an actual function. And tkinter.Button() is with a capital 'B' 

import tkinter
def click_function():
    print("WEWE")

def main():
    main_window = tkinter.Tk()
    main_window.title("free communism here")
    communism_button = tkinter.Button(text = "click for free communism", command = click_function, height = 40, width = 120)
    communism_button.pack()
    main_window.mainloop() # call here main_window instead of tkinter
main()

Try this way:

#!/usr/bin/env python3
from tkinter import *
def main():
    main_window = Tk()
    main_window.title("free communism here")
    click_function = print("WEWE")
    communism_button = Button(text = "click for free communism", command = click_function, height = 40, width = 120)
    communism_button.pack()
    main_window.mainloop()
main()
