Why am I getting an IndentationError when my code is properly indented?
<p>Below is my entire code. When trying to execute it, I keep getting the error message </p>

<pre><code>File "/Users/thomas/prac.py", line 15
  elif choice == "1":
IndentationError: expected an indented block 
</code></pre>

<p>Now I'm sure my indenting is right (I didn't mix tabs and spaces!) but I don't know why this isn't working:</p>

<pre><code>keepProgramRunning = True
while keepProgramRunning:
    print "Pleases choose an option: "
    print "0"
    print "1"

    choice = raw_input()

    if choice == "0":
        #do something
    elif choice == "1":
        print "Bye"
        keepProgramRunning = False
    else:
        print "try again"
</code></pre>

<p>What's wrong?</p>
