Return a list of weekdays
<p>My task is to deﬁne a function <code>weekdays(weekday)</code> that returns a list of weekdays, starting with weekday. It should work like this:</p>

<pre><code>&gt;&gt;&gt; weekdays('Wednesday')
['Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday', 'Monday', 'Tuesday']
</code></pre>

<p>So far I've come up with this one:</p>

<pre><code>def weekdays(weekday):
    days = ('Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday',
            'Sunday')
    result = ""
    for day in days:
        if day == weekday:
            result += day
    return result
</code></pre>

<p>But this prints the input day only:</p>

<pre><code>&gt;&gt;&gt; weekdays("Sunday")
'Sunday'
</code></pre>

<p>What am I doing wrong?</p>
