if myval == 0: nyval=1 if myval == 1: nyval=0
Is there a better way to do a toggle in python, like a nyvalue = not myval ?

Answer
Use the not
boolean operator:
nyval = not myval
not
returns a boolean value (True
or False
):
>>> not 1 False >>> not 0 True
If you must have an integer, cast it back:
nyval = int(not myval)
However, the python bool
type is a subclass of int
, so this may not be needed:
>>> int(not 0) 1 >>> int(not 1) 0 >>> not 0 == 1 True >>> not 1 == 0 True
