python - Pandas - Filtering None Values

Question

I'm using Pandas to explore some datasets. I have this dataframe:

I want to exclude any row that has a city value. So I've tried:

new_df = all_df[(all_df["City"] == "None") ]
new_df

But then I got an empty dataframe:

It works whenever I use any value other than None. Any idea how to filter this dataframe?

Answer 1

Consider using isnull() to locate missing values

all_df[all_df['City'].isnull()]
