There is no special .. ("dot dot") notation syntax in python. You can, however, see this in case of floats accessing their properties. For example,
f = 1..__truediv__ # or 1..__div__ for python 2 print(f(8))
This will give the output:
0.125
What we have is a float literal without the trailing zero, which we then access the __truediv__ method of. It's not an operator in itself; the first dot is part of the float value, and the second is the dot operator to access the object's properties and methods. This can also be achieved using:
>>> f = 1. >>> f 1.0 >>> f.__truediv__
