How to check whether a pandas DataFrame is empty?

Question

How to check whether a pandas DataFrame is empty? In my case I want to print some message in terminal if the DataFrame is empty.

Answer 1

I prefer going the long route. These are the checks I follow to avoid using a try-except clause -

1. check if variable is not None
2. then check if its a dataframe and
3. make sure its not empty

Here, DATA is the suspect variable -

DATA is not None and isinstance(DATA, pd.DataFrame) and not DATA.empty
