Raspberry Pi - Python中的GPIO(Raspberry Pi - GPIO in Python)
我试图让我的Raspberry Pi的GPIO引脚工作，我正在遵循教程：如何像Arduino一样使用你的Raspberry Pi 。
（我正在通过运行Raspbian的SSH工作。）我已经成功安装了分发版。
在尝试安装PIP时，我收到如下所示的错误。
我该如何解决它？

( I'm working through SSH running Raspbian.) I have successfully installed distribute.
When trying to install PIP, I get the error shown below.
How can I fix it?

直截了当的正则表达式：
var str = "abc kskd 8.900 prew"; var result = Regex.Split(str, @"\W(\d.*)").Where(x => x!="").ToArray();straightforward with a regular expression:

我不认为韩语在这里有任何相关性......我能想到的唯一问题就是在前3个字符之后的那个讨厌的逗号会阻止你使用直接的s.split()但正则表达式是强大的！ import re s = '굿모닝, Today is 촉촉' re.split(',?\s', s) 输出['굿모닝', 'Today', 'is', '촉촉'] 只需用可选的逗号分隔你的字符串,? 后跟一个非可选的白色字符\s I don't think Korean has any relevance here... The only issu ...

你可以让正则表达式做所有繁重的工作，首先将你的字符串分成几对： String[] pairs = aString.split("\\?(?!\\?)"); 那个正则表达式意味着“a？没有后跟？”，它给出了： [name==p==, header=hello, aname=????, lname=lastname] 然后还将结果拆分为名称/值，仅拆分第一个“=”： String[] split = pair.split("=", 2); // max 2 parts 把它们放在一起： String aS ...
