How to Remove Quotes from a String using Python

I am working to a huge dataframe, which is getting loaded from a csv file.

The data in this dataframe are randomly having used quotes (both " & ') and i basically need to remove all these quotes from all the data.

Some common examples of quotes usage is :

url = "''"
base_string = "My task was to test "task details" specifically."

From the above mentioned samples, if we consider the url, i want it to be as

url = ""

and base_string to be 

base_string = "My task was to test task details specifically."

I hope I had clarified my concern. Seeking any guidance in this regards.
