===Quotes===

We've been using double quotes around our strings, but you can use either double or single quotes:

 'Hello'
 "Hello"

Like with spacing above, use whichever quotes make the most sense for you, but be consistent.

You do have to be careful about using quotes inside of strings:

 'I'm a happy camper'

This gives us another '''traceback''', for a new kind of error, a <code>SyntaxError</code>. When Python looks at that expression, it sees the string 'I' and then

<code>m a happy camper'</code>

which it doesn't understand -- it's not 'valid' Python. Those letters aren't variables (we haven't assigned them to anything), and that trailing quote isn't balanced. So it raises a <code>SyntaxError</code>.

We can use double quotes to avoid this problem:

 "I'm a happy camper"

One fun thing about strings in Python is that you can multiply them:

 "A" * 40
 "ABC" * 12
 h = "Happy"
 b = "Birthday"
 (h + b) * 10
