在Python中,可以使用subprocess模块来运行具有实时输出的子进程。下面是一个示例代码: 代码语言:txt 复制 import subprocess def run_subprocess_with_realtime_output(command): process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, shell=True) while True: output = process....
output = subprocess.Popen(["mycmd", "myarg"], stdout=subprocess.PIPE).communicate()[0] 或者 >>> import subprocess >>> p = subprocess.Popen(['ls', '-a'], stdout=subprocess.PIPE, ... stderr=subprocess.PIPE) >>> out, err = p.communicate() >>> print out . .. foo 如果您设置...
subprocess.check_output() subprocess.check_output()用于执行命令并返回其输出。如果命令返回非零退出状态,将引发subprocess.CalledProcessError异常。 import subprocess try: output = subprocess.check_output(['ls', '-l']) print('Command output:', output.decode()) except subprocess.CalledProcessError as e...
