For loops are an essential part of any programmers tool belt. They look weird at first but once you know how they work it all makes sense.
1. Open up a new file either in Idle or your favorite text editor.
2. Then save it to a file on your desktop that you will easily be able to navigate to from the terminal.
3. Lets start off with defining a list, so type:
animals = ["dog","cat","bird","godzilla"]
4. Now, below the list you just made type:
for x in animals: print(x)
5. You should see output like this:
dog cat bird godzilla
6. Simple enough right? As you can probably tell, the x is the variable that is incremented up each time through the for loop in order to reach the end of the list. You can use any variable instead of x, Just make sure it does not conflict with any variables you have already defined.
