The bytes() method returns a bytes object of the given Syntax: bytes( ]])Ĭode : > x = b "Bytes objects are immutable sequences of single bytes" >ī 'Bytes objects are immutable sequences of single bytes' > Longbytesitem ::= longbyteschar | bytesescapeseq Shortbytesitem ::= shortbyteschar | bytesescapeseq Shortbytes ::= "'" shortbytesitem* "'" | '"' shortbytesitem* '"' How do we declare a single byte variable in Python? I would like to achieve the following result represented in C:ĭifference between bytes and bytearray object in Python,Define a mapping table characters for use with a bytes object in Python,Numeric code representing a character of a bytes object in Python,bytes() and bytearray() functions Bytes literals bytesliteral ::= bytesprefix(shortbytes | longbytes)īytesprefix ::= "b" | "B" | "br" | "Br" | "bR" | "BR" Choosing between options 1 and 2 depends on what you're using it for different use cases call for different approaches (though indexing/iterating the bytes object would get you the int values if you need to use both forms). Three choices:,The final option is largely for dealing with C functions through ctypes, it's otherwise slow/not Pythonic. The bytes object anycodings_byte would get you the int values if you need anycodings_byte to use both forms).Īn int that you don't assign values outside range(256) (or use masking to trim overflow): mychar = 0xff,A length 1 bytes (or bytearray) object mychar = b'\xff' (or mychar = bytearray(b'\xff')),Python doesn't differentiate between characters and strings the way C does, nor does it care about int bit widths.

I would like to know if it is possible to anycodings_byte declare an 8-bit variable in Python. Variable in anycodings_byte Python? I would like to achieve the anycodings_byte following result represented in C: The 'r' prefix can be used to disable processing of escape sequences: Only ASCII characters are allowed, and any character value greater than 127 must be specified using an appropriate escape sequence. Single, double, or triple quoting mechanisms can be used.
