os.system(command) 这个函数可以调用shell运行命令行command并且返回它的返回值。试一下在python的解释器里输入os.system(”ls-l”),就可以看到”ls”列出了当前目录下的文件。可以说,通过这个函数,python就拥有了shell的所有能力。呵呵。。不过,通常这条命令不需要用到。因为shell常用的那些命令在python中通常有对应...

多次执行exec_command函数 如果我们需要多次执行shell脚本,可以使用一个循环来实现。下面是一个示例代码: commands=['command_1','command_2','command_3']forcommandincommands:stdin,stdout,stderr=ssh.exec_command(command)forlineinstdout.readlines():print(line.strip()) 1. 2. 3. 4. 5. 6. 7. 8....
Python的运行方式主要有以下几种: 交互式解释器(Interactive Interpreter): 在命令行界面(如Windows的CMD、PowerShell或Linux/MacOS的终端Terminal)中输入python或python3(取决于系统默认设置或安装的Python版本),即可进入Python的交互式环境。在这种模式下,每输入一行Python语句,解释器会立即执行并返回结果。 脚本式运行(Scr...
python中command执行shell命令脚本方法 在Python中有一个模块commands也很容易做到以上的效果. 看一下三个函数: 1). commands.getstatusoutput(cmd) 用os.popen()执行命令cmd, 然后返回两个元素的元组(status, result),其中 status为int类型,result为string类型。cmd执行的方式是{ cmd ; } 2>&1, 这样返回结果...
