bytearray()

Returns an array of the given bytes of an object.

bytearray(source, encoding, error)

• source (optional): specifies the source to initialize the bytearray.
• encoding(optional): specifies the encoding method of the object.
• errors (optional): specifies the action to take in case of error.

Use bytearray() to encode the string "Welcome to Codecademy!" to unicode utf-8 and utf-32, and print the length of each bytearray. Note that a source and encoding parameter must be provided for encoding string data:

array_1 = bytearray("Welcome to Codecademy!", "utf-8")
array_2 = bytearray("Welcome to Codecademy!", "utf-32")

print(array_1)
print(len(array_1))

print(array_2)
print(len(array_2))

The output would be:

bytearray(b'Welcome to Codecademy!')
