In Python, a bytearray is a mutable sequence of bytes. It can be used to store and manipulate binary data, such as images or sound files. However, sometimes you may need to convert a bytearray to a single byte. This article will discuss how to achieve this in Python. Converting Bytea...
>>> myByteArray = bytearray(numbers) >>> print(myByteArray) bytearray(b'\x01\x02\x03\x04') Here the syntax we have used is bytearray(iterable_of_ints) Depending on the type of data we wish to convert into an array of bytes, the ByteArray class gives us 4 different constructors...
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(). If it is an integer, the array will have that size and will be initialized with null bytes. If it is an object conforming to th...

Thebytearray()method returns a bytearray object which is anarrayof the given bytes. Example prime_numbers = [2,3,5,7] # convert list to bytearraybyte_array = bytearray(prime_numbers) print(byte_array)# Output: bytearray(b'\x02\x03\x05\x07') ...
The optionalsourceparameter can be used to initialize the array in a few different ways: If it is astring, you must also give theencoding(and optionally,errors) parameters;bytearray()then converts the string to bytes usingstr.encode(). ...

# Convert the byte string to a string using the decode() method decoded_string = byte_string.decode("utf-8") # Print the decoded string print(decoded_string) 在此示例中,我们定义一个字节字符串,并使用具有 UTF-8 字符编码的方法将其转换为字符串。生成的解码字符串是 ,然后将其打印到控制台。b...
swapped_byte_array = bytes(swapped_byte_list) 将交换后的字节串转换回十六进制字节数组:使用hex()函数将交换后的字节串转换为十六进制字符串,然后按照每两个字符分割为一个字节,得到交换后的十六进制字节数组。以下是一个示例代码: 代码语言:txt 复制 ...
