If statement with multiple conditions but only check others if first fails

I'm trying to test two conditions, but only want to check the second condition if the first one fails. One example could be:

if df is None or len(df) == 0:
     # do something

I know I can use two seperate if statements or a try...except block. However, I want to know if there is a more elegant pythonic way of doing it or is two seperate if statements the only way.

or is a short-circuit operator in python 3. This means the second condition (here len(df) == 0) is executed only if the first one (here df is None) is false.

You can running your code like this:

if df == none:
    # Do this

elif len(df) == 0:
    # Do this

else:
    # Do this

It works fine and can definately help
