本文着重讲解了Python常用类型转换实现代码实例,文中通过代码实例讲解的非常细致，对大家的工作和学习具有一定的参考学习价值,欢迎大家阅读和收藏
1.byte和str互转
b = b"example"
s = "example"
bytes(s, encoding = "utf8")
str(b, encoding = "utf-8")
2.byte和int互转
b=b'\x01\x02'
num=int.from_bytes(b,'little')
b1=num.to_bytes(2,'little')
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')
