<jupyter_start><jupyter_text>What do you hate about pandas?I started a thread on the data science subreddit [What do you hate about pandas?](https://www.reddit.com/r/datascience/comments/7ggdlz/what_do_you_hate_about_pandas/) I have some things that I think could be changed.* Keep only two indexers **`.loc`** and **`.iloc`*** Many methods are not needed and can be deprecated. I like keeping the library as small as possible* Make the documentation more accessible to beginning programmers* Better renaming conventions after a groupby  Mastering Pandas* Article on [How to Learn Pandas](https://medium.com/dunder-data/how-to-learn-pandas-108905ab4955)* Read the entire documentation * Do lots of end-to-end data analyses (kaggle datasets and kernels)* Answer questions on Stack Overflow* Create tutorials  Code ReviewDo you have a small snippet of code you would like to share?
