求解! 为什么这段代码在我这一直报错啊?(新手)
import tkinter as tkclass App:
def __init__(self,master):
frame = tk.Frame(master)
frame.pack()
self.hi_there = tk.Button(frame,text="打招呼",bg='black',fg="blue",command=self.say_hi)
self.hi_there.pack()
def say_hi(self):
print("gcygucgcgw")
root = tk.Tk()
app = App(root)
root.mainloop()
报错信息:
Traceback (most recent call last):
