如何显示 dataframe 的 MultiIndex object？

Question

I had a data frame jobs_2 which has many columns, amongst which are 'city' and 'state'.

From jobs_2 I created a new data frame 'jobs_2i' where state and city are set as indices of jobs_2.

For that I used the code:

jobs_2i = jobs_2.set_index(['state', 'city'])

I now need to use an appropriate property of data frames to display the MultiIndex object of jobs_2i, but I am unsure how to do that.

I'm not sure exactly what you are asking for, but here is a quick example of using a MultiIndex:

df = pd.DataFrame(data).set_index(['state', 'city'])
df.loc['California']  # Gets me everything with state is california
df.loc[('California', 'Los Angeles')]  # Gets me everything in Los Angeles, CA

Is that what you were looking to solve? Otherwise, can you try and give me an example?
