在RF协议中处理的txt问题

Question

我正在编写协议以便通过RF发送信息。我从txt获取信息，我希望将每个字母拆分为一个字节，然后通过Raspberry Pi中的协议SPI将其发送到RF模块。当我尝试发送新的行号代码（\n）时，我的代码出现问题。有谁能够帮我？提前谢谢！

informationpacket1=array.array('B')
informationpacket2=array.array('B')
informationpacket3=array.array('B')
informationpacket4=array.array('B')

    for i in range (0, 4):
        if i==0:
            for i0 in range (0, 23):
                lectura=origen.read(1)
                origenbinario1=int(binascii.hexlify(lectura), 16)
                informationpacket1.insert(i0,origenbinario1)
        elif i==1:
            for i1 in range (0, 23):
                lectura=origen.read(1)
                origenbinario2=int(binascii.hexlify(lectura), 16)
                informationpacket2.insert(i1,origenbinario2)
