整数->字节(int to bytes) 使用to_bytes函数。 *int.to_bytes(length, byteorder, , signed=False) 1. length是转换后的字节数 自己规定大小,但如果取小了,就会报错 OverflowError: int too big to convert 1. byteorder确定用于表示整数的字节顺序 如果byteorder 是“big” ,则最高有效字节位于字节数组的开...

s = str(n) i = int(s) # Python 3. s = bytes(str(n), "ascii") i = int(s) 我特别关心两个因素:可读性和可移植性。第二种方法,对于 Python 3,是丑陋的。但是,我认为它可能是向后兼容的。 有没有我错过的更短、更清洁的方式?我目前制作了一个 lambda 表达式来用一个新函数修复它,但也许...

encounters an error, it prevents consuming the rest of the message. In my opinion, it would be nice to have an option to handle these situations. The user should be able to choose whether to let it break and throw an exception or not convert the data field where a similar issue is ...
