pandas.DataFrame.empty — pandas 0.18.1 documentation (original) (raw)

DataFrame.empty¶

True if NDFrame is entirely empty [no items], meaning any of the axes are of length 0.

Notes

If NDFrame contains only NaNs, it is still not considered empty. See the example below.

Examples

An example of an actual empty DataFrame. Notice the index is empty:

df_empty = pd.DataFrame({'A' : []}) df_empty Empty DataFrame Columns: [A] Index: [] df_empty.empty True

If we only have NaNs in our DataFrame, it is not considered empty! We will need to drop the NaNs to make the DataFrame empty:

df = pd.DataFrame({'A' : [np.nan]}) df A 0 NaN df.empty False df.dropna().empty True
