解决subprocess.Popen启动两条进程

问题：使用subprocess.Popen启动进程时，启动了两条进程，如何解决？

解决：添加executable='bash'

方法：

cmd_date = 'python test_01.py'
process = subprocess.Popen(cmd_date, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True, executable='bash')
stdout, stderr = process.communicate()
print(stdout, stderr, process.pid)
