Python如何将字符串转换为字节？

Question

我需要转换像“aa28f5c91a24293a3278”这样的字符串以获得字节形式的结果，比如“b'\xaa（\xf5\xc9\x1a$）：2x'” 如何在python中实现这一点？谢谢

Answer 1

与^{}一起：

>>> s = "aa28f5c91a24293a3278"
>>> bytes.fromhex(s)
b'\xaa(\xf5\xc9\x1a$):2x'

This bytes class method returns a bytes object, decoding the given string object. The string must contain two hexadecimal digits per byte, with ASCII whitespace being ignored.
