3.byte和float互转
import struct
s=b'@zQ\x16'
def byteToFloat(b):
return struct.unpack('!f',s)[0]
def floatToBytes(f):
bs = struct.pack("f",f)
return bytes((bs[3],bs[2],bs[1],bs[0]))
f1=byteToFloat(s)
floatToBytes(f1)4.str和bytearray互转
str1='aaabb'
ba=bytearray(str1,encoding='utf-8')
str2=ba.decode('utf8')推荐教程：《Python教程》
