  </code></pre>
  
  <p>After splitting on  "  " I got this output</p>
  
  <pre><code>#code for splitting
  split_facility = facility_series.apply(lambda x: x.split("  "))
  split_facility[0]  #first element
  
  output:
  ['Home Delivery',
   ' Vegetarian Only',
   'Valet Parking AvailableIndoor SeatingKid FriendlyPet FriendlyVegan OptionsOutdoor SeatingCatering AvailableSelf ServiceServes Jain FoodDesserts and Bakes']
  </code></pre>
  
  <p>Here I noticed that in some values of the list the consecutive facilities have merged like <em>["Valet Parking AvailableIndoor Seating"]</em> which otherwise should be ["Valet Parking Available", "Indoor Seating"]<br>
  I want the output to be like this:-</p>
  
  <pre><code>[['Home Delivery','Vegetarian Only','Valet Parking Available','Indoor Seating','Kid Friendly','Pet Friendly','Vegan Options','Outdoor Seating','Catering Available','Self Service','Serves Jain Food','Desserts and Bakes']
  ['Wheelchair Accessible','Serves Non Veg','Full Bar Available','Indoor Seating','Free Wifi','Free Parking','Outdoor Seating','Table booking recommended','Brunch']]
