python多重同步fi

Question

如何使用Python3打开多个fifo？ 下面的代码非常简单，但它在最后一行堆叠并等待（？）。。。 有什么需要帮忙的吗

   toAgent = ['ABCD', 'EFGH', 'IJKL', 'MNOP',]

   def createPipe():

        for i in range(0, len(toAgent)):
            #print(i)
            fifoName = '../tmp/' + toAgent[i]       
            if not os.path.exists(fifoName):
                os.mkfifo(fifoName) 

                pipeName = 'pipe_' + str(i)
                print(pipeName, fifoName)
                pipeName = os.open(fifoName, os.O_WRONLY )

Answer 1

import os
toAgent = ['ABCD', 'EFGH', 'IJKL', 'MNOP',]

def createPipe():
    for i in range(0, len(toAgent)):
            #print(i)
        fifoName = '../tmp/' + toAgent[i]
        if not os.path.exists(fifoName):
            os.mkfifo(fifoName)

            pipeName = 'pipe_' + str(i)
            print(pipeName, fifoName)
            pipeName = os.open(fifoName, os.O_WRONLY )

createPipe()
