 Sometimes you will need to use an apostrophe within a single quote, on occasions like this it is recommended to use string escaping. This would look like:

 ### Decision making using variables
 
-Now that we know how to use variables and know how to store data, let's play around with decision making and changing prints based on your answer. In Python (and many other languages), one of the most commons ways in which this is done is using an if statement. For example:

 	if number > 3:
 		print "Bigger than three"
 	elif number < 3:
 		print "Smaller than three"
 
-Here we can see that if a number we have passed into this decision making code is bigger than three, we will recieve a messag telling us so, and the same relevant message if the number is smaller than three.

 Also, now that we are getting more in depth with Python, we should say that Python is very particular about tabbing. Tabbing is the indents created when writing code. With Python, if any lines are not indented correctly the code will not run. If you are running into bugs, this is a good place to start.
