我对 python 很陌生。我想知道，使用时subprocess.Popen需要关闭连接还是子进程自动关闭连接？

process = subprocess.Popen(["mysql", "-uroot", "-ppassword", "database"], 
           stdin = subprocess.PIPE, 
           stdout = subprocess.PIPE, 
           stderr = subprocess.PIPE) 
process_out, process_err = process.communicate(file("test.sql").read())
print process_out
