Calling the Python built in function bytes on the array a does the same thing, although tobytes() allows you to specify the memory layout (as per the documentation). If a has a type which uses more bytes for each number, your byte string might be padded with a lot of unwanted null b...
Is this the best way to convert a Python number to a hex string? number =123456789hex(number)[2:-1].decode('hex') Sometimes it doesn't work and complains about Odd-length string when you do 1234567890. Clarification: I am going from int to hex. Also, I need it to be escaped. IE...

上述类图中,我们定义了一个名为Integer的类,该类包含两个方法:to_bytes()和from_bytes()。这两个方法分别用于将整数转换为字节和将字节转换为整数。 流程图 下面是一个使用mermaid语法表示的整数拆字节的流程图: InputConvertOutput 上述流程图表示了整数拆字节的过程。我们首先输入一个整数,然后通过转换操作将其转...
bytearray([source[, encoding[, errors]]])The optional source parameter can be used to initialize the array in a few different ways:If it is a string, you must also give the encoding (and optionally, errors) parameters; bytearray() then converts the string to bytes using str.encode()....
