本文实例为大家分享了python tkinter实现简单计算器的具体代码，供大家参考，具体内容如下

import tkinter as tk
 
input_num_ls = []
first_num = None
calculator_method = None
 
 
def get_num(ls):
 
    new_ls = [10 ** i * float(num) for i, num in enumerate(ls)]
 
    ls_sum = sum(new_ls)
 
    if int(ls_sum) == ls_sum:
        return int(ls_sum)
     
    else:
        return ls_sum
 
 
def append_num(num):
    global input_num_ls
    if len(num) < 10:="" input_num_ls.append(num)="" else:="" input_num_ls.append(num[:10])="" current_value.set(get_num(input_num_ls))="" print(input_num_ls)="" def="" append_calculator(method):="" global="" input_num_ls,="" first_num,="" calculator_method="" calculator_method="method" first_num="get_num(input_num_ls)" input_num_ls="[]" print('method',="" calculator_method)="" def="" calculator_result():="" global="" first_num,="" input_num_ls,="" calculator_method="" second_num="get_num(input_num_ls)" input_num_ls.clear()="" if="" calculator_method="=" '+':="" current_value.set(second_num="" +="" first_num)="" input_num_ls.append(str(second_num="" +="" first_num))="" elif="" calculator_method="=" '-':="" current_value.set(first_num="" -="" second_num)="" input_num_ls.append(str(first_num="" -="" second_num))="" elif="" calculator_method="=" '*':="" current_value.set(first_num="" *="" second_num)="" input_num_ls.append(str(second_num="" *="" first_num))="" elif="" calculator_method="=" '/':="" current_value.set(first_num="" second_num)="" input_num_ls.append(str(first_num="" second_num))="" print(first_num,="" second_num,="" calculator_method)="" def="" clear():="" global="" first_num,="" input_num_ls,="" calculator_method="" first_num="None" input_num_ls="[]" calculator_method="None" current_value.set(0)="" def="" func():="" pass="" #="" 主体窗口="" window="tk.Tk()" #="" 设置窗口="" 标题="" window.title('简易计算器')="" #="" 设置窗口="" 宽高="" window.geometry('400x300')="" #="" 添加user显示屏幕背景="" screen_area="tk.Frame(width='400'," height='100' ,="" bg='#ddd' )="" #="" 放置到window中="" screen_area.pack()="" #="" 示例设置显示的数据类="" current_value="tk.StringVar()" current_value.set(0)="" #="" 数字显示框="" #="" anchor="" 文本相对于标签中心的位置="" 默认是center="" n="" s="" w="" e="" show_screen_label="tk.Label(screen_area," textvariable="current_value," bg='white' ,="" width='400' ,="" height='2' ,="" font="{'黑体'," 40,="" 'bold'},="" anchor='e' )="" show_screen_label.pack(padx="10," pady="6)" #="" 按键区域="" button_area="tk.Frame(width='300'," height='300' ,="" bg='#ccc' )="" button_area.pack(padx="10," pady="5)" #="" 添加button="" tk.button(button_area,="" text='C' ,="" width='5' ,="" height='1' ,="" command="lambda:" clear()).grid(row='1' ,="" column='0' )="" tk.button(button_area,="" text='+' ,="" width='5' ,="" height='1' ,="" command="lambda:" append_calculator('+')).grid(row='1' ,="" column='1' )="" tk.button(button_area,="" text='-' ,="" width='5' ,="" height='1' ,="" command="lambda:" append_calculator('-')).grid(row='1' ,="" column='2' )="" tk.button(button_area,="" text='*' ,="" width='5' ,="" height='1' ,="" command="lambda:" append_calculator('*')).grid(row='1' ,="" column='3' )="" tk.button(button_area,="" text='7' ,="" width='5' ,="" height='1' ,="" command="lambda:" append_num('7')).grid(row='2' ,="" column='0' )="" tk.button(button_area,="" text='8' ,="" width='5' ,="" height='1' ,="" command="lambda:" append_num('8')).grid(row='2' ,="" column='1' )="" tk.button(button_area,="" text='9' ,="" width='5' ,="" height='1' ,="" command="lambda:" append_num('9')).grid(row='2' ,="" column='2' )="" tk.button(button_area,="" text='/' ,="" width='5' ,="" height='1' ,="" command="lambda:" append_calculator('/')).grid(row='2' ,="" column='3' )="" tk.button(button_area,="" text='4' ,="" width='5' ,="" height='1' ,="" command="lambda:" append_num('4')).grid(row='3' ,="" column='0' )="" tk.button(button_area,="" text='5' ,="" width='5' ,="" height='1' ,="" command="lambda:" append_num('5')).grid(row='3' ,="" column='1' )="" tk.button(button_area,="" text='6' ,="" width='5' ,="" height='1' ,="" command="lambda:" append_num('6')).grid(row='3' ,="" column='2' )="" tk.button(button_area,="" text='=' ,="" width='5' ,="" height='1' ,="" command="lambda:" calculator_result()).grid(row='3' ,="" column='3' )="" tk.button(button_area,="" text='1' ,="" width='5' ,="" height='1' ,="" command="lambda:" append_num('1')).grid(row='4' ,="" column='0' )="" tk.button(button_area,="" text='2' ,="" width='5' ,="" height='1' ,="" command="lambda:" append_num('2')).grid(row='4' ,="" column='1' )="" tk.button(button_area,="" text='3' ,="" width='5' ,="" height='1' ,="" command="lambda:" append_num('3')).grid(row='4' ,="" column='2' )="" tk.button(button_area,="" text='C' ,="" width='5' ,="" height='1' ,="" command="lambda:" clear()).grid(row='4' ,="" column='3' )="">
