Python converting hex string to hex little endian byte code

Question

I'm trying to do this

pack("<Q", 0x401a12)

It works as it is, but I need pack() to take string hex code

addr = "0x401a12" # some hex from dump
pack("<Q", addr)

Any help?

您可以使用int转换为相应的整数：

struct.pack('<Q', int('0x401a12', base=16))
