get the dtype of a pandas multiindex

Question

How can I find the dtype of a MultiIndex in pandas without printing out all the values (this happens if you type df.index, for example

Answer 1

Use get_level_values:

df.index.get_level_values(0).dtype
dtype('int64')

and

df.index.get_level_values(1).dtype
dtype('int64')

For names use:

df.index.names
FrozenList(['i1', 'i2'])

Answer 2

Based on the great answer by @Scott Boston, I wrote this function for a quick check for the dtypes of all the levels of multiindex dfs and just thought I'd share:

def index_level_dtypes(df):
    return [f"{df.index.names[i]}: {df.index.get_level_values(n).dtype}"
            for i, n in enumerate(df.index.names)]
