-####While and For Each Loops
-
-In this challenge, we're going to write a while loop, a For In loop, and nest them.
-
-###While Loops
-
-A while loop iterates until a condition is no longer true. For example:
-
-		while(greg == alive){
-			live_year(1)
-			age++
-		}
-
-Seemingly, a while loop could be endless. In that case, we have to break it. Take the following example:
-		
-		i = 0
-
-		while(true){
-			i++
-			print("I'm an endless loop")
-			if(i >= 50){
-				break;
-			}
-		}
-
-This will run exactly 50 times.
-
-###For In
-
-A For In loop iterates through each index in the data structure. In an array, an index is an integer, that starts at 0. Take this example:
-
-		var array = ['john', 'bobby', 'homa', 'stevie', 'rob']
-
-		for(var i in array){
-			console.log(i) // prints 0, 1, 2, 3, 4
-		}
-
-In an object however, the index is a string. Check this out:
-
-		var obj = {'john': 'student', 'bobby': 'programmer', 'homa': 'actress', 'stevie': 'gamer'}
-
-		for(var k in obj){
-			console.log(k) // prints 'john', 'bobby', 'homa', 'stevie'
-		}
-
-###Sandbox
-
-Try this on your own in your node console or browser console. Declare some objects, iterate through them, print them out.
-
-Also check out [.forEach](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach)
-
-###Multiplication Tables
-
-Using any loop / loops of your choosing, write code that prints the multiplication tables up to a number input by the user in a form.
-
-Create the form that gets the user input yourself above the #printout div, and append the result to the printout div.
-
-Bonus if you actually use a table.
-
-Your return should look something like this:
-
-		// userinput = 7
-
-0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |  
-1 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |  
-2 | 2 | 4 | 6 | 8 | 10| 12| 14|  
-3 | 3 | 6 | 9 | 12| 15| 18| 21|  
-4 | 4 | 8 | 12| 16| 20| 24| 28|  
-5 | 5 | 10| 15| 20| 25| 30| 35|  
-6 | 6 | 12| 18| 24| 30| 36| 42|  
-7 | 7 | 14| 21| 28| 35| 42| 49|

+While Loops in Python
+=====================
+
+A while loop iterates until a condition is no longer true. For example:
+```
+i = 0
+while i < 10:
+	print(i)
+	i += 1
+```
+Be careful with while loops. If your while loop doesn't have a way to end, it will go on until it crashes.
+```
+i = 10
+while i > 5:
+	print(i)
+	i += 1
+```
+
+#### Multiplication Tables
+
+Using any loop / loops of your choosing, write code that prints the multiplication tables up to a number
+
+Your return should look something like this:  
+```
+# userinput = 7
+
+0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |  
+1 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |  
+2 | 2 | 4 | 6 | 8 | 10| 12| 14|  
+3 | 3 | 6 | 9 | 12| 15| 18| 21|  
+4 | 4 | 8 | 12| 16| 20| 24| 28|  
+5 | 5 | 10| 15| 20| 25| 30| 35|  
+6 | 6 | 12| 18| 24| 30| 36| 42|  
+7 | 7 | 14| 21| 28| 35| 42| 49|
+```
+Python does not change data types for you. If you would like to mix an integer and "|" into a string, you have to explicitly change the integer into a string. the method str() will do this for you.
+```
+1 + "c" # this won't work
+str(1) + "c" # this will be "1c"
+```
