TypeError: Can't convert 'bytes' object to str implicitly >>> s.count(by.decode('ascii')) (3) 1 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. ① 不能连接bytes对象和字符串。他们两种不同的数据类型。 ② 也不允许针对字符串中bytes对象的出现次数进行计数,因为串里面根本没有bytes。字...
# 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...

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}") ...
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. ...
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(). ...

>>> 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...
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') ...
