I come from a c style languages, so I am natural in using `!=` as not equal, but when I came to Python, from the documentation I read, I learned that for this purpose the `<>` operator is used. 

Recently, I have seen a lot of code using `!=`, so my question is if one of them is preferred over the other or is one of them deprecated.

Also, I would like to know if there is any difference between them.
