os.system(command) Execute the command (a string) in a subshell. This is implemented by calling the Standard C function system(), and has the same limitations. Changes to sys.stdin, etc. are not reflected in the environment of the executed command. If command generates any output, it will...
Execute shell commands via os.popen()and return status, output. Interface summary: import commands outtext= commands.getoutput(cmd) (exitstatus, outtext)= commands.getstatusoutput(cmd) outtext= commands.getstatus(file)# returns output of "ls -ld file" A trailing newlineis removedfrom the ou...
os.system(command)返回命令执行状态码,而将命令执行结果输出到屏幕; os.popen(command).read() 可以获取命令执行结果,但是无法获取命令执行状态码; commands.getstatusoutput(command) 返回一个元组(命令执行状态码, 命令执行结果); os.popen(command)函数得到的是一个文件对象,因此除了read()方法外还支持write()等...
System Command Output Write a Python program to get system command output. Sample Solution: Python Code: # Import the subprocess module to run shell commands. import subprocess # Use the 'subprocess.check_output' function to execute the 'dir' command in the shell. ...
Execute the stringcmdin a shell withos.popen()and return a 2-tuple(status,output).cmdis actually run as{cmd;}2>&1, so that the returned output will contain output or error messages. A trailing newline is stripped from the output. The exit status for the command can be interpreted acco...
res = os.system(command) #the method returns the exit status print("Returned Value: ", res) Output: Python 3.7.4 Returned Value: 0 Here, res stores the returned value (exit code=0 for success). It is clear from the output, that the command is executed successfully and we get our Py...
