Python 如何从文本文件中读取最后10个字节？

以上内容在我的文本文件中

如何从该文本文件中读取最后10个字节？预期产出为：

Welcome to demofile.txt
This file is for testing purposes.
Good Luck!

那么：

in_file.seek(-10, 2)  # where 2 denotes the reference point being the end of the file

输出：

in_file = open("demofile.txt", "rb") # opening for [r]eading as [b]inary
in_file.seek(-10, 2)
s = in_file.read(10)
print(s)

可能是重复的，它帮助我@user5126最后10个字节@KenY-N为此进行了编辑。

in_file = open("demofile.txt", "rb") # opening for [r]eading as [b]inary
in_file.seek(-10, 2)
s = in_file.read(10)
print(s)

b'Good Luck!'
