    self.make_frame2()
    self.make_frame3()

    self.frame0.grid(row=4, column=0)
    self.frame1.grid(row=4, column=1)
    self.frame2.grid(row=4, column=2)

  def get(self):
     if self.coding_button:
       print("ok")
     elif self.gamedev_button:
       print("poyo") 
     elif self.digitalmedia_button:
       print("GUH-HUH")
      

if __name__ == "__main__":
    app = App("YTAC")
    app.mainloop()

This def function will only print out the first string and not the other two even though I pressed all corresponding buttons.

Expected corresponding string to print out after I pressed the corresponding button. I tried to change the elifs to their own if statements but that caused more problems.

Without seeing all of the code I cannot accurately diagnose your problem, but it may lie in how you’re using the Tkinter buttons.

Another question that seems similar to yours
To Detect Button Press In Python Tkinter Module

A very thorough tutorial for Tkinter buttons:
https://www.tutorialspoint.com/python/tk_button.htm

Essentially, Tkinter buttons are defined like so:

buttonName = tkinter.Button(master, option1=value1, option2=value1...)

Tkinter buttons have no "is pressed" variable, instead, you set the command (a function) that runs when the button is pressed.

buttonName = tkinter.Button(master, command=function_name, option1=value1, option2=value2...)

Note: Don’t put parentheses after the function name as that will run the function. The only exception is if you have a function that returns a function

If you want a global variable that’s changed when you push the button, a function like so works:

global_var = False
def callback():
    global global_var
    global_var = not global_var
button = tkinter.Button(master, command=callback)

In the above example, replace master with the name of the Tkinter window.
