    我就废话不多说了,直接上代码吧!

    # coding:utf8
    import base64
     
     
    def BaseToFlow():
      while True:
        str = input("Please input src: ")
        flag = input("Please input Decode - 1 or Encode - 2: ")
        if str == "":
          str = "ApIAGBcEAAAEBO6x3nLykEEhjWMX1wHs"
        if flag == "":
          flag = "1"
        if flag == "1":
          print("Decoding ...")
          dst = base64.b64decode(str)
          # print(type(dst))
          # <class 'bytes'>
          # print(dst)
          # b'\x02\x92\x00\x18\x17\x04\x00\x00\x04\x04\xee\xb1\xder\xf2\x90A!\x8dc\x17\xd7\x01\xec'
          # print(dst.hex()) --去掉\0x前缀 得到一个字符串
          # 02920018170400000404eeb1de72f29041218d6317d701ec
          HexFormat(dst.hex())
        elif flag == "2":
          print("Encoding ...")
          dst = base64.b64encode(str)
          print(dst)
     
     
    def HexFormat(str):
      """
      :param str: 16进制连续字符串
      :return: 码流格式的16进制串
      """
      i = 1
      str2 = ""
      while (i <= len(str)):
        str2 = str2 + str[i - 1] + str[i] + " "
        if (i + 1) %16 == 0 and (i + 1) % 32 != 0:
          str2 = str2 + " "
        elif (i + 1) %32 == 0:
          str2 = str2 + "\n"
        i = i + 2
     
     
    if __name__ == '__main__':
      BaseToFlow()
    

    结果:

    Please input src: 
    Please input Decode - 1 or Encode - 2: 
    Decoding ...
