# 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!
1. Convert Bytes to String Using the decode() Method The most straightforward way to convert bytes to a string is using thedecode()method on the byte object (or the byte string). This method requires specifying the character encoding used. Note: Strings do not have an associated binary enco...
(string memory _name) public{ // convert string to bytes first // then convert to bytes8 bytes8 newName=bytes8(bytes(_name)); Names.push(newName); }} 或者你也可以把过去作为论据 function setName(bytes8 _name) public{ Names.push(_name); } 在前端调用时,将字符串转换为字节8,然后将其...

Using array2string method The easiest way to convert a Numpy array to a string is to use the Numpy array2string dedicated function. import numpy as np my_array = np.array([1, 2, 3, 4, 5, 6]) print(f"My array: {my_array}") ...

>>> 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 constructor...
If it is astring, you must also give theencoding(and optionally,errors) parameters;bytearray()then converts the string to bytes usingstr.encode(). If it is aninteger, the array will have that size and will be initialized with null bytes. ...
