python : why is this invalid syntax? : <p>i wrote this code to draw circles and hexagons.</p>

<pre><code>import turtle
t = turtle.Turtle()
t.shape("turtle")
for(int i=1; i&lt;=6; i++){
t.circle(100)
t.forward(100)
t.left(60)
t.forward(100)
t.left(60)
t.forward(100)
t.left(60)
t.forward(100)
t.left(60)
t.forward(100)
t.left(60)
t.forward(100)
}
</code></pre>

<p>i made "int i" to iterate but debugging says it's invalid syntax. why?
i'm not native english speaker, so if you could please tell me easily. i'll be really appreciated. </p>
