看下程序是不是有等待用户输入,或者死循环,或者运行时间比较长。

pyinstaller打包处理的程序用不了
warn-xxx.txt文件的信息如下,求大佬处理 This file lists modules PyInstaller was not able to find. This does not necessarily mean this module is required for running you program. Python and Python 3rd-party packages include a lot of conditional or optional module. For example the module 'ntpath' only exists on Windows, whereas the module 'posixpath' only exists on Posix systems. Types if import: * top-level: imported at the top-level - look at these first * conditional: imported within an if-statement * delayed: imported from within a function * optional: imported within a try-except-statement IMPORTANT: Do NOT post this list to the issue-tracker. Use it as a basis for yourself tracking down the missing module.

python自动化测试的问题,比较两个波形文件,能用方差直接比较么?
主要是有两个波形文件,它们由不同的方式生成,一个是期望值,一个是要测试的,我是想知道,如果写了一个方差的函数variance(),可不可以直接variance(wavefile1)和variance(wavefile2)这样比较?

大神给我讲讲python中build是怎么回事吧
有时候装一个第三方库时,看到除了安装还有build,比如这下面这个: Get segyio A copy of segyio is available both as pre-built binaries and source code: In Debian unstable apt install python3-segyio Wheels for Python from PyPI pip install segyio Source code from github git clone https://github.com/statoil/segyio Source code in tarballs Build segyio To build segyio you need: A C99 compatible C compiler (tested mostly on gcc and clang) A C++ compiler for the Python extension, and C++11 for the tests CMake version 2.8.12 or greater Python 2.7 or 3.x. numpy version 1.10 or greater setuptools version 28 or greater setuptools-scm pytest To build the documentation, you also need sphinx To build and install segyio, perform the following actions in your console: git clone https://github.com/Statoil/segyio mkdir segyio/build cd segyio/build cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local make make install 我pip install 这个segyio包不是就可以用了吗?还需要build吗?这个build是什么意思呢?

截止目前,我已经分享了如下几篇文章: 一个程序在计算机中是如何运行的?超级干货!!! 作为一个程序员,CPU的这些硬核知识你必须会! 作为一个程序员,内存的这些硬核知识你必须懂! 这些知识可以说是我们之前都不太重视的基础知识,可能大家在上大学的时候都学习过了,但是嘞,当时由于老师讲解的没那么有趣,又加上这些知识本身就比较枯燥,所以嘞,大家当初几乎等于没学。 再说啦,学习这些,也看不出来有什么用啊!...
渗透测试-灰鸽子远控木马
木马概述 灰鸽子( Huigezi),原本该软件适用于公司和家庭管理,其功能十分强大,不但能监视摄像头、键盘记录、监控桌面、文件操作等。还提供了黑客专用功能,如:伪装系统图标、随意更换启动项名称和表述、随意更换端口、运行后自删除、毫无提示安装等,并采用反弹链接这种缺陷设计,使得使用者拥有最高权限,一经破解即无法控制。最终导致被黑客恶意使用。原作者的灰鸽子被定义为是一款集多种控制方式于一体的木马程序...

作者:@明哥 公众号:Python编程时光 2020年,这个看起来如此浪漫的年份,你还是一个人吗? 难不成我还能是一条狗? 18年的时候,写过一篇介绍如何使用 Python 来表白的文章。 虽然创意和使用效果都不错,但有一缺点,这是那个exe文件,女神需要打开电脑,才有可能参与进来,进而被你成功"调戏”。 由于是很早期的文章了,应该有很多人没有看过。 没有看过的,你可以点击这里查看:用Pyt...
用Python开发实用程序 – 计算器
作者:隋顺意 一段时间前,自己制作了一个库 “sui-math”。这其实是math的翻版。做完后,python既然可以轻易的完成任何的数学计算,何不用python开发一个小程序专门用以计算呢? 现在我们越来越依赖于计算器,很多复杂的计算都离不开它。我们使用过各式各样的计算器,无论是电脑自带的,还是网也上的计算器,却都没有自己动手编写属于自己计算器。今天就让我们走进计算器的世界,用python来编写...

整理一波国外前端学习网站
国内的普通开发者对于掌握一门新的技术不知道从哪里下手,看哪些书。为了获得相关知识会关注各种公众号、购买各种视频课程来学习,但由于这些内容本身有碎片化的特点,效果往往不太理想。以至于付出了大量的时间到最后不能够形成系统化的知识。 我同样也遇到过类似的问题,不是说公众号与视频课程不好,这些也有自身的优势,但是往往都是别人经过实践沉淀下来的,我们读过之后往往仅限于了解而已。如果要掌握还需要大量的实践、探...
