Other people have explained the difference between the name "a" and the object it's bound to... but to the extent that "a" is an integer, yes it most definitely is an object. To be specific, the integer 10 is an object, as you can see thus: >>> a = 10 >>> a.to_bytes(4, "big") b'\x00\x00\x00\n' >>> (a*12+8).to_bytes(4,"big") b'\x00\x00\x00\x80' Every expression [1] in Python has a value which is some sort of object, so you can do method calls on anything at all. Sometimes this looks a bit odd, but it does work: >>> 7.25.as_integer_ratio() (29, 4) The floating-point number 7.25 is represented in Python as a float object, and float objects have methods, same as all objects do. In this case, I've asked Python to tell me what this number would be as a fraction (ratio) of integers - 29/4 is equal to 7.25, so that's what it returns. So yes! It is an object. Everything is an object! ChrisA [1] To silence the nitpickers: An expression could raise an exception, or not terminate at all. As Grandpa said in The Princess Bride, you're very clever, now shut up. -- https://mail.python.org/mailman/listinfo/python-list
