I have a list of hex strings representing bytes, of the form "FF". I want to convert the whole list to a byte stream so I can send it over a socket (Python 3). It looks like the bytearray type would work, but I can't find any way to directly convert the list to a bytearray...
# convert list to bytearraybyte_array = bytearray(prime_numbers) print(byte_array)# Output: bytearray(b'\x02\x03\x05\x07') bytearray() Syntax The syntax ofbytearray()method is: bytearray([source[, encoding[, errors]]]) bytearray()method returns a bytearray object (i.e. array of...
关键的步骤包括导入模块、创建数组、使用tobytes()方法进行转换以及输出结果。以下是对应的类图和状态图,旨在帮助你更好地理解整个过程和状态变化。 类图 convertArray+array_type: str+elements: list+tobytes() : bytesByteArray+data: bytes 状态图 tobytes()ArrayCreatedConversionInProgressByteArrayCreated 结尾 通...
在上述代码中,首先定义了一个字符串列表string_list,包含了两个字符串元素。然后使用列表推导式将每个字符串元素通过encode()方法转换为字节,并将结果存储在byte_list中。 需要注意的是,encode()方法默认使用UTF-8编码将字符串转换为字节。如果需要使用其他编码方式,可以在encode()方法中指定相应的参数,例如encode('...

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()....

The representation of bytearray objects uses the bytes literal format (bytearray(b'...')) since it is often more useful than e.g. bytearray([46,46, 46]). You can always convert a bytearray object into a list of integers using list(b)....
