* Outline
  In this tutorial, we shall look at
    + Using if/else blocks 
    + Using if/elif/else blocks
    + Using the Ternary conditional statement

* Question 1
  Given a number, num. Write an if else block to print num, as is, if
  it is divisible by 10, else print 10 * num.
* Solution 1
  #+begin_src python
    if num%10 == 0: 
        print num   
    else:           
        print 10*num
  #+end_src

* ~if/elif~ ladder
  #+begin_src python
    if user == 'admin':
        # Do admin operations
    elif user == 'moderator':
        # Do moderator operations
    elif user == 'client':
        # Do customer operations
  #+end_src
* Question 2
  Given a number, num. Write a ternary operator to print num, as is,
  if it is divisible by 10, else print 10 * num.
* Solution 2
  #+begin_src python
    print num if num%10 == 0 else 10*num
  #+end_src
* Summary
  In this tutorial session we learnt

    + What are conditional statements
    + if/else statement
    + if/elif/else statement
    + Ternary conditional statement - ~C if X else Y~
    + and the ~pass~ statement

* Thank you!
