python 字符串16进制

要将Python字符串转换为16进制字符串，可以使用binascii库中的b2a_hex()函数。以下是一个示例代码：

import binascii
string = "开心"
hex_string = binascii.b2a_hex(string.encode()).decode()
print(hex_string)

运行上述代码，将输出字符串"开心"的16进制表示：e5bc80e5bf83。

请注意，binascii.b2a_hex()函数用于将字符串编码为十六进制字符串，参数需要是字节类型，因此需要使用.encode()方法将字符串编码为字节。而输出结果为字节类型，所以需要使用.decode()方法将其解码为字符串。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
