The subprocess<\/code> module: <\/mark><\/strong>This module provides a way to spawn new processes, connect to their input\/output\/error pipes, and obtain their return codes. It is a powerful and flexible way to call external programs from Python. Here’s an example:<\/p>\n\n\n\nimport subprocess\r\n\r\n# Call an external program and capture its output\r\nresult = subprocess.run(['ls', '-l'], stdout=subprocess.PIPE)\r\n\r\n# Print the output\r\nprint(result.stdout.decode())\r<\/code><\/pre>\n\n\n\nsubprocess.run()<\/code> function is used to call the ls<\/code> command with the -l<\/code> option, which lists the contents of the current directory in a long format. The stdout<\/code> argument is set to subprocess.PIPE<\/code>, which captures the output of the command. The output is then printed to the console using print()<\/code>.<\/p>\n\n\n\n
The os<\/code> module:<\/mark><\/strong> <\/mark>This module provides a way to interact with the operating system, including running external programs. Here’s an example:<\/p>\n\n\n\nimport os\r\n\r\n# Call an external program\r\nos.system('ls -l')\r<\/code><\/pre>\n\n\n\nos.system()<\/code> function is used to call the ls<\/code> command with the -l<\/code> option. The output is printed directly to the console.<\/p>\n\n\n\n
The sh<\/code> module: <\/strong><\/mark>This module provides a way to run shell commands from Python. Here’s an example:<\/p>\n\n\n\nimport sh\r\n\r\n# Call an external program\r\nresult = sh.ls('-l')\r\n\r\n# Print the output\r\nprint(result)\r<\/code><\/pre>\n\n\n\nsh.ls()<\/code> function is used to call the ls<\/code> command with the -l<\/code> option. The output is captured in a variable and then printed to the console using print()<\/code>. Note that the sh<\/code> module requires that the external program be installed on the system and accessible from the shell.<\/p>\n","protected":false},"excerpt":{"rendered":"
