Check if pandas column contains all zeros [duplicate]

Question

I'm doing a complex calculation on a data frame that is bound to throw exceptions if all the values in a column are zeros. How to do a quick check whether a column is full of zero? i.e. return True if the column has values other than 0 else False.

Answer 1

you can do something like this:

(df['col'] == 0).all()

This will return True if all values are 0 otherwise it will return false
