What does it mean for DataFrame.ix to be deprecated?
Yes, deprecated here means that the attribute or method has been removed from the newer versions. Hence, it is advised to avoid them in your code to avoid future issues.
Suppose I use DataFrame.ix in some code.
Does the fact that it's deprecated mean that at some point in the future, I'm going to update pandas, and then a little bit later, the stuff using that code will mysteriously start to break because they decided that finally, they were going to actually remove ix?
