Как проверять нажата ли клавиша 'c' на python?

 import tkinter  
import pyautogui  
import os  
import keyboard  
root = tkinter.Tk ()  
root.geometry('400x200')  
root.wm_attributes("-topmost",1)  
root.title("бизнес")  
def enter():  
    global doxod, balance  
    balance = e.get()  
    balance = str(balance)  
    doxod = t.get()  
    doxod = str(doxod)  
    f = open("C:/Desktop/money/balxod.txt", "w+")   
    f.write(balance + "\n")  
    f.write(doxod)  
    f.close()  
    root.withdraw()  
  
keyboard.read_key()  
if keyboard.read_key() == "c":  
    root.deiconify()  
e = tkinter.Entry()  
e.pack()  
t = tkinter.Entry()  
t.pack()  
btn1 = tkinter.Button(root, text='enter', command=enter)  
btn1.pack()  
root.withdraw()  
  
root.mainloop()
