bytes() function converts an object (such as a list, string, integers, etc.) into an immutable
bytes object within the range of 0 to 256. If no object is provided to the
bytes() method, it can generate an empty
bytes object of a specified size.
This method can be declared in two ways, depending on the requirement:
The return value of the
bytes() function varies in two ways depending upon the parameters:
If an integer indicating the size of the
bytes is passed into the function, it returns an empty
bytes object of the specified size.
Instead of a size, a string, tuple, or a list is passed into the
bytes() method, it is converted into a corresponding
bytes object. In this case, the encoding for the string, tuple, or list can be specified, and hence encoding is an optional parameter.
A third optional argument is passed in the function that tells what to do if the method fails to cater to the errors.
bytes object of a specific size is created in the example below, i.e.,
# specify size size = 6 #generate empty bytes object of size 6: byteArray = bytes(size) # output: b'\x00\x00\x00\x00\x00\x00' print(byteArray)
Here, no specific size of the required
bytes is given because an object, i.e., string, is passed into the function. Also, the encoding method “utf-8” is provided in the given instance:
givenString = ["Welcome", "to", "educative"] # given_string is encoded into bytes object according to utf-8 byteArray = bytes(givenString,'útf-8') # output: b'Welcome to educatve' print(byteArray)
Similarly, an object, in this case, a tuple is passed into the
bytes() function to generate
bytes object corresponding to it without mentioning any encoding type.
tup = (1, 2, 3, 4, 5) # tuple is converted into bytes object without specifying any encoding type byteArray = byte(tup) # outputs: b'\x01\x02\x03\x04\x05' print(byteArray)
