Missing Argument / issues opening GUI program on macOS Big Sur - python-3.x

Question

This is my first GUI program and I am having some major issues. I really need some help. First, I cannot get the program to open on my computer (mac). When running in Idle IDE I get this error message: import Tkinter
ModuleNotFoundError: No module named 'Tkinter'.
I have 3.9 installed which I thought had a GUI interface.
When debugging in VS Code i get this error message # line 44:
Exception has occurred: TypeError
init() takes at least 4 arguments (3 given)
I think I have 4
I'm not sure where to begin with these issues. From my research it appears that there is an issue running GUI programs on macs updated higher then 11.1.
Code is below
# Create a Tkinter GUI program that converts Celsius Temp to Fahrenheit
# F == Fahrenheit
# C == Celsius
# Tkinter imported
import Tkinter
# Global variable used
temp_val = 'Celsius'
#Set value for drop down menu
def store_temp (set_temp):
global temp_val
temp_Val = set_temp
class TemperatureConverter:
def __init__(self):
# create main window
self.main_window = Tkinter.Tk()
# create a title for window
self.main_window.title('Temperature Converter')
# create three frames
self.top_frame = Tkinter.Frame()
self.option_frame = Tkinter.Frame()
self.mid_frame = Tkinter.Frame()
self.bottom_frame = Tkinter.Frame()
#create widget for top frame
self.prompt_label = Tkinter.Label(self.top_frame, text= 'Enter a temperature in Celsius: ')
#pack top frame
self.prompt_label.pack(side='left')
# create str variable obj to hold empty string variable
self.inputNumber = Tkinter.StringVar()
self.var = Tkinter.StringVar()
# create widget for option drop down menu
self.entry = Tkinter.Entry(self.option_frame, textvariable=self.inputNumber )
self.dropDownList = ['Celsius','Fahrenheit']
self.drop_down = Tkinter.OptionMenu(self.option_frame, value=self.var , values=self.dropDownList, command=store_temp)
self.var.set(dropDownList[0])
# option widgets packed
self.entry.pack(side='right')
self.dropDownList.pack(side='left')
#create widget for middle frame
self.result_label = Tkinter.Label(self.mid_frame)
# create widgets for bottom frame
self.call_convert = (call_convert , result_label, inputNumber)
self.convert_button = Tkinter.Button(self.bottom_frame, text='Convert', command=self.call_convert)
self.quit_button= Tkinter.Button(self.bottom_frame, text= 'Quit', command= self.main_window.destroy)
#pack the buttons
self.convert_button.pack(side='left')
self.quit_button.pack(side='left')
#pack the frames
self.top_frame.pack()
self.option_frame.pack()
self.mid_frame.pack()
self.bottom_frame.pack()
#Enter the tkinter main loop
Tkinter.mainloop()
# convert method is callback fucntion for convert button
def call_convert(self):
if temp_Val == 'Celsius':
f = float((float(temp)* 9/5)+32)
self.result_label.config(text='The temperature in Fahrenhiet is:')
if temp_Val == 'Fahrenheit':
c = float((float(temp)-32) * 5 / 9)
self.result_label.config(text='The temperature in Celsius is:')
if __name__ == '__main__':
temp_converter = TemperatureConverter()

There were a lot of bugs in your code. I fixed all of them (I think). I had to guess where you wanted to put the label with the results. I also had to fix all of the indentations. This is the working code:
# Create a tkinter GUI program that converts Celsius Temp to Fahrenheit
# F == Fahrenheit
# C == Celsius
# tkinter imported
import tkinter
class TemperatureConverter:
def __init__(self):
# create main window
self.main_window = tkinter.Tk()
# create a title for window
self.main_window.title("Temperature Converter")
# create three frames
self.top_frame = tkinter.Frame(self.main_window)
self.option_frame = tkinter.Frame(self.main_window)
self.mid_frame = tkinter.Frame(self.main_window)
self.bottom_frame = tkinter.Frame(self.main_window)
# create widget for top frame
self.prompt_label = tkinter.Label(self.top_frame, text="Enter a temperature in Celsius:")
# pack top frame
self.prompt_label.pack(side="left")
# create str variable obj to hold empty string variable
self.inputNumber = tkinter.StringVar(self.main_window)
self.var = tkinter.StringVar()
# create widget for option drop down menu
self.entry = tkinter.Entry(self.option_frame, textvariable=self.inputNumber)
self.dropDownList = ["Celsius", "Fahrenheit"]
self.drop_down = tkinter.OptionMenu(self.option_frame, self.var, *self.dropDownList)
self.var.set(self.dropDownList[0])
# option widgets packed
self.entry.pack(side="right")
self.drop_down.pack(side="left")
# create widget for middle frame
self.result_label = tkinter.Label(self.mid_frame)
# create widgets for bottom frame
self.convert_button = tkinter.Button(self.bottom_frame, text="Convert", command=self.call_convert)
self.quit_button= tkinter.Button(self.bottom_frame, text= "Quit", command=self.main_window.destroy)
# pack the buttons
self.convert_button.pack(side="left")
self.quit_button.pack(side="left")
# pack the frames
self.top_frame.pack()
self.option_frame.pack()
self.mid_frame.pack()
self.bottom_frame.pack()
# It is better to call `<tkinter.Tk>.mainloop()`
self.main_window.mainloop()
# convert method is callback fucntion for convert button
def call_convert(self):
if self.var.get() == "Celsius":
f = float((float(self.entry.get())* 9/5)+32)
self.result_label.config(text="The temperature in Fahrenhiet is: "+str(f))
if self.var.get() == "Fahrenheit":
c = float((float(self.entry.get())-32) * 5 / 9)
self.result_label.config(text="The temperature in Celsius is: "+str(c))
self.result_label.pack(side="bottom")
if __name__ == "__main__":
temp_converter = TemperatureConverter()
Look at what I did for the OptionMenu and look at how I fixed you call_convert function. If you have any specific questions, tell me and I will try to answer them.
By the way I don't think any of the errors you were getting were caoused by your OS. Also I suggest that next time you use import tkinter as tk as it will make it way easier to write code.
