# What is python .. ("dot dot") notation syntax?

PythonProgrammingServer Side Programming

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__
