python字节转换

1、导入模块

from bitstring import BitArray
import binascii
import socket

2、二进制转换为字节

bin_str = '0b00000000'
data_bytes = BitArray(bin=bin_str).bytes   #中间有\x
data_bytes = binascii.b2a_hex(data_bytes)   #中间无\x

3、字符串转字节

bytes_str = 'AA55'
data_bytes = bytes_str.encode('utf-8')

4、十进制转字节

data_bytes = binascii.b2a_hex(np.uint8(12))
data_bytes = binascii.b2a_hex(np.int16(8192))

5、字节拼接

data_bytes = data_1_bytes + data_2_bytes

6、socket udp可直接发送

send_soc = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
send_soc.sendto(data_bytes, ('127.0.0.1', 8888))
