最近在学习Python GUI， 选择的是 python 自带的 tkinter，优点是简单、快捷，缺点是不够美观。学了两天，用40行代码写了个简单的计算器，供大家学习参考。

源代码如下
from tkinter import *
window = Tk()
window.title('计算器')
window.attributes("-topmost", 1) # 窗口置顶
str1 = ''
def input(msg):
"""输入"""
global str1
str1 = str1 + msg
text(str1)
def text(msg):
"""输出"""
label_show.config(text=msg)
def clear():
"""清除"""
global str1
label_show.config(text='')
str1 = ''
def get_result():
"""计算"""
global str1
label_show.config(text=eval(str1))
str1 = str(eval(str1))
label_show = Label(window, bg='yellow', width=30, height=5)
label_show.grid(row=0, column=0, columnspan=4, pady=4)
Button(window, text='1', font=('黑体', 15), width=3, command=lambda: input('1')).grid(row=1, column=0, padx=4, pady=4)

window.mainloop()
利用 pyinstaller 打包成exe，大小8m
打包命令如下：
打包命令解释：打包成单个可执行文件，指定ico，不显示命令行窗口
pyinstaller -F -w --icon=D:\IDM下载\ico\jisuanqi.ico --onefile jisuanqi.py
