convert pandas series from str to int

df['DataFrame Column'] = df['DataFrame Column'].astype(int)

Here is what the above code is Doing:
1. We’re creating a new column called ‘DataFrame Column’
2. We’re setting the value of each row in that column to whatever the value was in column ‘A’
3. We’re deleting column ‘A’
4. We’re changing the data type of the new column from float to integer
