see in above output length is different president_name 18 row while terms_of_office 14 row

Solution 

president_na = []


for item in president:
    parts = item.split('\n')
    if len(parts) > 1:
        president_na.append(parts[0])      
president_na
Enter fullscreen mode Exit fullscreen mode 
term_of = []

for item in president:
    parts = item.split('\n')
    if len(parts) > 1:

        term_of.append(parts[1])

term_of
Enter fullscreen mode Exit fullscreen mode 
import pandas as pd
datas= pd.DataFrame({'president_name':president_na,'terms_of_office':term_of})
datas
Enter fullscreen mode Exit fullscreen mode
