Output of Dataframe.info()

Could someone explain what the “574 to 1061” means? The values in the index column are definitely wider ranging than that - have to be since there are 3000+ entries…

Hi @ananth.ch,

574 is the first index in Int64Index and 1061 - the last index. They are not even the max and min values of the indices.

It seems that your Int64Index has many duplicated values. Most probably, you dropped some rows and didn’t reset the index afterwards.

To avoid this issue, just reset the index before calling df.info():


In this case, you will have correct numbers in df.info() output.

Hi ananth.ch

I guess you might have coded like this
dc_listings = dc_listings.loc[np.random.permutation(len(dc_listings))] dc_listings.info()
Hence the output:

You can check and see that 574 is the first index, and 1061 is the last index in the DataFrame, which is now a random form of the original dataset.

Hope its clear now.


Thanks. So it is the first and last rather than the min and max…

Yes, these are the index values of the first and last rows.
