-* Outline
-  - Slicing strings to get sub-strings
-  - Reversing strings
-  - Replacing characters in strings. 
-  - Converting strings to upper or lower case
-  - Joining a list of strings
-* Question 1
-  Obtain the sub-string excluding the first and last characters from
-  the string ~s~.
-* Solution 1
-  #+begin_src python
-    In []:  s[1:-1]
-  #+end_src
-* Question 2
-  Given a list week, week = ~week = ["sun", "mon", "tue", "wed",
-  "thu", "fri", "sat"]~. Check if ~s~ is a valid name of a day of the
-  week. Change the solution to this problem, to include forms like,
-  SAT, SATURDAY, Saturday and Sat.
-* Solution 2
-  #+begin_src python
-    In []:  s in week
-    In []:  s.lower()[:3] in week
-  #+end_src
-* Question 3
-  Given ~email~ -- ~info@fossee[dot]in~
-
-  Replace the ~[dot]~ with ~.~ in ~email~
-* Solution 3
-  #+begin_src python
-    email.replace('[dot], '.')
-    print email
-  #+end_src
-* Question 4
-  From the ~email_str~ that we generated, change the separator to be a
-  semicolon instead of a comma.
-* Solution 4
-  #+begin_src python
-    email_str = email_str.replace(",", ";")
-  #+end_src
-* Summary
-  You should now be able to --
-  - Slice strings and get sub-strings out of them
-  - Reverse strings
-  - Replace characters in strings. 
-  - Convert strings to upper or lower case
-  - Join a list of strings
-
-* Thank you!
