一、commands模块 1、介绍 当我们使用Python进行编码的时候,但是又想运行一些shell命令,去创建文件夹、移动文件等等操作时,我们可以使用一些Python库去执行shell命令。 commands模块就是其中的一个可执行shell命令的库,commands模块是python的内置模块,共有三个函数: getstatus(file):返回执行 ls -ld file 命令的结果(...
1、subprocess.call(command, shell=True)#会直接打印出结果。 2、subprocess.Popen(command, shell=True) 也能够是subprocess.Popen(command, stdout=subprocess.PIPE, shell=True) 这样就能够输出结果了。假设command不是一个可运行文件,shell=True是不可省略的。shell=True意思是shell下运行command。 #===下面转载...
方法二、使用os.popen(),该方法以文件的形式返回shell指令运行后的结果,需要获取内容时可使用read()或readlines()方法,举例如下: 方法三、使用commands模块,有三个方法可以使用: (1)commands.getstatusoutput(cmd),其以字符串的形式返回的是输出结果和状态码,即(status,output)。 (2)commands.getoutput(cmd),返回...

python之commands模块(执行 commands模块 用于执行Linuxshell命令,要获得shell命令的输出只需要在后面参数写入('命令')就可以了。 需要得到命令执行的状态则需要判断$?的值, 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(命令)...
为了使这些值更容易处理,您可以使用 Python 的内置round()函数来缩短它们,该函数将浮点数舍入到您指定的精度。只需传入您想要舍入的数字,加上可选的第二个参数,表示您想要舍入到小数点后多少位。如果省略第二个参数,round()会将数字舍入到最接近的整数。在交互式 Shell 中输入以下内容:...
