if Statements

• Allow conditional block execution
• If you're looking for C's switch statement, use if/elif/else
• Simple

  >>> x = 1
  >>> if x:
  ... 	print "x is a true value"
  ... 
  x is a true value

• Slight less simple, but still simple nontheless

  >>> color = "yellow"
  >>> if color == "green":
  ... 	print "go!"
  ... elif color == "yellow":
  ... 	print "slow down..."
  ... elif color == "red":
  ... 	print "stop!"
  ... 
  slow down...
