【Python学习笔记（九）】字符串、Bytes 、16进制Bytes相互转换(转载)

前言

此篇文章介绍字符串、Bytes 、16进制Bytes之间的相互转换，文章转载至：python字符串/Bytes/16进制/x01等之间的转换

正文

1、格式转换方法

1. 字符串–>Bytes ：bytes("需要转换的字符串", encoding = "utf8")
2. Bytes–>16进制Bytes：binascii.unhexlify("Bytes")
3. 16进制Bytes–>Bytes：binascii.hexlify("16进制Bytes")
4. Bytes–>字符串：str("Bytes", encoding = "utf-8")

2、转换示例代码

text = "0123456789abcdef"
print(text)
b_text = bytes(text, encoding = "utf8")
print(b_text)
hex_text = binascii.unhexlify(b_text) #a2b_hex
print(hex_text)
b_ctext = binascii.hexlify(hex_text) #b2a_hex
print(b_ctext)
ctext = str(b_ctext, encoding = "utf-8")
print(ctext)

3、转换输出效果

0123456789abcdef
b'0123456789abcdef'
b'\x01#Eg\x89\xab\xcd\xef'
b'0123456789abcdef'
0123456789abcdef
