python - 试图在 tkinter 中打印我的菜单 gui 的总成本。ERROR = 'int' 对象不可调用
问题描述
嗨，我在尝试将这个菜单聊天机器人变成 gui 时遇到了麻烦，我有一些代码不匹配，一旦在第 108 行单击“完成订单”，我就可以打印所有项目的总成本
所有代码：
from tkinter import *
cost = 0
class Window(Frame):
def __init__(self, master=None):
Frame.__init__(self, master, bg='#DA291C')
self.master = master
self.init_window()
def init_window(self):
self.master.title("Maccas Menu")
self.pack(fill=BOTH, expand=1)

self.TooMany.grid(row=20, column=1)
else:
self.Total_Maccas_num(row=20, column=1)
def check(self):
if self.delivery.get() == True:
self.Address.configure(state='normal')
self.Phone_Number.configure(state='normal')
else:

self.Phone_Number.configure(state='disabled')
def show_entry_fields(self):
global cost
print("\n Name: {}\n Address: {}\n Phone Number: {}" .format(self.Name.get(), self.Address.get(), self.Phone_Number.get()))
print(self.delivery.get())
if self.delivery.get() == True:
cost += 3
print(cost)
root = Tk()
root.geometry("400x600")
app = Window(root)
root.mainloop()
这是我感到困惑的部分，需要一些帮助。
def Maccas_Submit(self):
self.Total_Maccas_num = int(self.BigMac_num.get()) + int(self.Nuggets_num.get()) + int(self.AngusBurger_num.get()) + int(self.Wraps_num.get()) + int(self.SoftServe_num.get()) + int(self.Fillet_o_Fish_num.get()) + int(self.HappyMeal_num.get()) + int(self.Salad_num.get()) + int(self.Sprite_num.get()) + int(self.Frozen_Coke_num.get()) + int(self.Apple_Pie_num.get()) + int(self.Apple_Slices_num.get())

如果有人可以解决这个问题，那将非常感谢。
解决方案
在内部Maccas_Submit()，您self.Total_Maccas_num已从IntVar(initialized inside init_window()) 更改为int：
def Maccas_Submit(self):
# below line changed self.Total_Maccas_num to 'int'
self.Total_Maccas_num = int(self.BigMac_num.get()) + int(self.Nuggets_num.get()) + int(self.AngusBurger_num.get()) + int(self.Wraps_num.get()) + int(self.SoftServe_num.get()) + int(self.Fillet_o_Fish_num.get()) + int(self.HappyMeal_num.get()) + int(self.Salad_num.get()) + int(self.Sprite_num.get()) + int(self.Frozen_Coke_num.get()) + int(self.Apple_Pie_num.get()) + int(self.Apple_Slices_num.get())
if int(self.Total_Maccas_num) > 5:
self.TooMany.grid(row=20, column=1)
else:
# below line tries to use 'int' as a function which causes the exception
self.Total_Maccas_num(row=20, column=1)
根据您的代码，我建议进行以下更改：
class Window(Frame):
...
def init_window(self):
...
self.Total_Maccas_num = IntVar()
Button(self, text='Finish Order',fg='#27251F',bg='#DA291C', command=self.Maccas_Submit).grid(row=16, column=0, sticky=W, pady=4, padx=5)
self.TooMany = Label(self, text = "Less than 5 items please.")
#self.TooMany.grid_remove() # not necessary
self.total_label = Label(self, textvariable=self.Total_Maccas_num) # added a label for the total
def Maccas_Submit(self):
total = int(self.BigMac_num.get()) + int(self.Nuggets_num.get()) + int(self.AngusBurger_num.get()) + int(self.Wraps_num.get()) + int(self.SoftServe_num.get()) + int(self.Fillet_o_Fish_num.get()) + int(self.HappyMeal_num.get()) + int(self.Salad_num.get()) + int(self.Sprite_num.get()) + int(self.Frozen_Coke_num.get()) + int(self.Apple_Pie_num.get()) + int(self.Apple_Slices_num.get())
if total > 5:
self.total_label.grid_forget() # hide the total_label
self.TooMany.grid(row=20, column=1) # show the warning
else:
self.TooMany.grid_forget() # hide the warning
self.Total_Maccas_num.set(total) # update total_label
self.total_label.grid(row=20, column=1) # show total_label
