# Given a pandas dataframe containing a pandas series/column of tuples B, 
# we want to extract B into B1 and B2 and assign them into separate pandas series

# Method 1: (faster)
# use pd.Series.tolist() method to return a list of tuples 
# use pd.DataFrame on the resulting list to turn it into a new pd.DataFrame object, while specifying the original df index
# add to the original df
