Python lambda 函数可用于 Tkinter 的 GUI 编程中。 它允许为command参数创建小的内联函数。 lambda_tkinter.py #!/usr/bin/python3 # -*- coding: utf-8 -*- from tkinter import Tk, BOTH, messagebox from tkinter.ttk import Frame, Button class Example(Frame): def __init__(self, parent): Fr...
原文:Python 2 and 3 Compatibility 协议:CC BY-NC-SA 4.0 一、打印、反引号和repr 打印是 Python 2 和 Python 3 之间最广为人知的区别。Python 2 中的 print 语句不需要括号;它是 Python 3 中的一个函数。反勾号 repr 也有区别。本章讨论了 Python 版本之间这些特性的差异以及实现其兼容性的技术。 打印...
In line 9, you’re looping through all your cards. Inside the card_list loop, you can access the fields of the Card model for each individual Card instance. It makes sense for a flashcards app to list all the flashcards on your home page. Replace the former landing page with a URL ...

可以与GUI程序库和工具箱实现无缝衔接。IPython可以和许多Python版的GUI工具箱/程序库无缝衔 接,如Tkinter、PyGTK、PyQt和wxPython。 集群管理:IPython可以通过MPI/异步状态回调信息对集群计算进行管理。 类UNIX运行环境:IPython的默认功能与UNIX命令行环境类似,支持客户自定义。
当你在使用Python的tkinter库创建GUI(图形用户界面)应用程序时,可以使用window.resizable(False, False)技术来控制窗口是否可调整大小。...这个技术有着重要的作用,特别是当你希望保持窗口的固定大小时。...保持设计一致性:如果你已经设计好了固定大小的界面,可以通过禁止调整大小来保持设计的一致性。...示例代码...
最近在查阅Tkinter相关资料,由于在安装后的Tkinter包路径(Python安装路径下的libkinter目录)并没有找到相关的官方文档(诸如pdf、html、chm、txt等格式的文件),所以就只能借助help()函数来查看其官方帮助信息了。 通过摸索,发现Python内置的help()函数能提供不少有用的信息,我在此做了一些归纳总结,特此分享给需要的朋友...
