Issue 2:
Code Sample, a copy-pastable example if possible

# A value is trying to be set on a copy of a slice from a DataFrame.

Problem description

It is better to add some hints beside this error, or this information will coufuse many people. Suggestion: you can add a sentence like "Maybe you should reset the index of the slice". It can be more clear to make modification.

[this should explain why the current behaviour is a problem and why the expected output is a better solution.]

Note: We receive a lot of issues on our GitHub tracker, so it is very possible that your issue has been posted before. Please check first before submitting so that we do not have to handle and close duplicates!

Note: Many problems can be resolved by simply upgrading pandas to the latest version. Before submitting, please check if that solution works for you. If possible, you may want to check if master addresses this issue, but that is not necessary.

For documentation-related issues, you can check the latest versions of the docs on master here:

https://pandas-docs.github.io/pandas-docs-travis/

If the issue has not been resolved there, go ahead and file it in the issue tracker.
