Can't convert Celsius to Fahrenheit
<p>Here's my code:</p>

<pre><code># Note: Return a string of 2 decimal places.
def Cel2Fah(temp): 
    fah = float((temp*9/5)+32)
    fah_two = (%.2f) % fah
    fah_string = str(fah_two)
    return fah_string
</code></pre>

<p>Here's what I should get:</p>

<pre><code>&gt;&gt;&gt; Cel2Fah(28.0)
    '82.40'
&gt;&gt;&gt; Cel2Fah(0.00)
    '32.00'
</code></pre>

<p>But I get an error:</p>

<pre><code>Traceback (most recent call last):
File "Code", line 4
fah_two = (%.2f) % fah
^
SyntaxError: invalid syntax
</code></pre>

<p>I'm not sure what is going on...</p>

<p>This doesn't seem to work either for some reason:</p>

<pre><code># Note: Return a string of 2 decimal places.
def Cel2Fah(temp): 
    fah = temp*9/5+32
    fah_cut = str(fah).split()
    while len(fah_cut) &gt; 4:
        fah_cut.pop()
    fah_shorter = fah_cut
    return fah_shorter
</code></pre>
