写入到sys.stdout的数据通常出现在屏幕上,但可使用管道将其重定向到另一个程序的标准输入。错误消息(如栈跟踪)被写入到sys.stderr,但与写入到sys.stdout的内容一样,可对其进行重定向,例如:$ cat somefile.txt | python somescript.py | sort。可以认为,somescript.py从其sys.stdin中读取数据(这些数据是somefil...
# Filename : helloworld.py print'Hello World' (源文件:code/helloworld.py) 为了运行这个程序,请打开shell(Linux终端或者DOS提示符),然后键入命令python helloworld.py。如果你使用IDLE,请使用菜单Edit->Run Script或者使用键盘快捷方式Ctrl-F5。 输出如下所示。

如果你和我一样是使用 SecureCRT,请设置 Session Options/Terminal/Appearance/Character Encoding 为 UTF-8 ,保证能够正确的解码 linux 终端的输出。 两个Python 字符串类型间可以用 encode / decode 方法转换: 1 2 3 4 5 #从 str 转换成 unicode
