I have a Python dictionary and I created a panda data frame like below:
I want to change the name of index column to date . But I couldn't do this with data.set_index('date') . How can I do this? Any advice would be appreciated.

Try `df.rename_axis('date')`, since date is already in index, you're probably looking to name the index. – Zero Sep 30 '17 at 13:17

Or `df.index.name = 'date'` – jezrael Sep 30 '17 at 13:18

@TheNone - If use some old version of pandas, `df.rename_axis('date')` should failed. – jezrael Sep 30 '17 at 13:52
