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...
bytes 和 bytearray 转换 bytearray 转 bytes 当需要将可变的bytearray转换为不可变的bytes时,可以直接使用bytes()构造函数。 #从 bytearray 转换为 bytesba=bytearray(b'Hello')b=bytes(ba)print(b)# 输出: b'Hello' 1. 2. 3. 4. bytes 转 bytearray 将bytes转换成bytearray也非常简单,只需使用bytearr...
# Convert the string to a bytes object bytes_object = bytes(string, 'utf-8') # Print the bytes object print(bytes_object) # Convert the bytes object back to a string decoded_string = bytes_object.decode('utf-8') # Print the decoded string print(decoded_string) 输出: b'Hello, world!
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...
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 are shown in the table below. ...
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') ...
Convert a bytearray to a integer array in Python I have the following bytearray on Python bytearray(b'\x02\xcb\x00\n\x02\xcb\x00\n\x02\xcb\x00\n\x02\xcb\x00\n\') and I want to conver the hexa values of the bytearray to an integer array of values converting the hexa to in...
The representation of bytes objects uses the literal format (b'...') since it is often more useful than e.g.bytes([46, 46, 46]). You can always convert a bytes object into a list of integers usinglist(b). Note For Python 2.x users: In the Python 2.x series, a variety of im...
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(). ...
Return an array of 4 bytes:x = bytearray(4) Try it Yourself » Definition and UsageThe bytearray() function returns a bytearray object.It can convert objects into bytearray objects, or create empty bytearray object of the specified size....
