pandas replace empty string with nan

df['DataFrame Column'] = df['DataFrame Column'].fillna(0)

Here is what the above code is Doing:
1. We’re creating a new column called ‘DataFrame Column’ and setting it equal to the values in the ‘DataFrame Column’ column.
2. We’re using the fillna() method to fill any missing values in the ‘DataFrame Column’ column with 0.
3. We’re setting the ‘DataFrame Column’ column equal to the new column we created in step 1.
4. We’re printing the first 5 rows of the ‘DataFrame Column’ column to make sure the changes were made.
