如何在文件中存储256作为整数？

Question

我正在学习LZW数据压缩，我想存储数字＆gt;文件中有255个。数字不应存储为字符串，否则压缩将无效。但是，二进制文件只存储数字＆lt; = 255.如何存储大于255的数字，这样当我读回它们时，我会得到原始整数？

lst = [256]

writefile = open("C:/Users/Dhruv/Desktop/write.bin", "wb")

buffer = bytes(lst)

print(buffer)

writefile.write(buffer)
writefile.close()
readfile = open("C:/Users/Dhruv/Desktop/write.bin", "rb")
bin = readfile.read(1)

print(ord(bin))

readfile.close()
