dropping empty columns in pandas 0.23+ [duplicate]

Question

In earlier versions of pandas, you could drop empty columns simply with:

df.dropna(axis='columns')

However, dropna has been depreciated in later builds. How would one now drop multiple (without specifically indexing) empty columns from a dataframe?

Answer 1

I am able to drop empty columns using dropna() with the current version of Pandas (0.23.4). The code I used is:

df.dropna(how='all', axis=1)

Looks like what is deprecated is passing multiple axes at once (i.e. df.dropna(how='all', axis = [0, 1]). You can read here that they made this decision - "let's deprecate passing multiple axes, we don't do this for any other pandas functions".
