How to create tuple with a loop in python : <p>I want to create this tuple:</p>

<pre><code>a=(1,1,1),(2,2,2),(3,3,3),(4,4,4),(5,5,5),(6,6,6),(7,7,7),(8,8,8),(9,9,9)
</code></pre>

<p>I tried with this</p>

<pre><code>a=1,1,1
for i in range (2,10):
    a=a,(i,i,i)
</code></pre>

<p>However it creates a tuple inside other tuple in each iteration.</p>

<p>Thank you</p>
