Python won't run a basic fibonacci function
<p>I'm new to python and can't figure out what the problem with simple fibonacci function is. It also calculates amount of iterations the function makes.</p>

<p>Here is the code:</p>

<pre><code>times = 0;

def fib(n):
    times = times + 1
    if n == 0:
        return 0
    elif n == 1:
        return 1
    else:
        return fib(n-1) + fib(n-2)
</code></pre>

<p>When I run it, for some reason I get this error:</p>

<pre><code>IndentationError: unindent does not match any outer indentation level

  File "fibo.py", line 7
    if n == 0:
             ^
</code></pre>

<p>What is the problem?</p>
