How to code this in Python 3 Conditional loop(I'm newbie:-))

[Pawelk198604]

import turtle   

Dlugo_PiS = turtle.Pen()
Dlugo_PiS.shape("turtle")
Dlugo_PiS.forward(200)
Dlugo_PiS.left(120)    
Dlugo_PiS.forward(200)    
Dlugo_PiS.left(120) 
Dlugo_PiS.forward(200) 
Dlugo_PiS.left(60) 
turtle.done()    
turtle.bye()

 Want to write it simpler   import turtle   

Dlugo_PiS = turtle.Pen()    
Dlugo_PiS.shape("turtle")   
    while i in range(3)
       Dlugo_PiS.forward(200)   
       Dlugo_PiS.left(120) 
turtle.done()
turtle.bye()  

What i need to do to make it works

You want a for loop, not a while loop.

Or you have to increment i within the loop, like this:

OOPS: Nevermind, Mike is correct. I've never used the range() function.

This is not python-specific.

For loops are used to iterate over a set number of things. Either a number of times, or (as is often used in Python) the members of a list.

While loops are used to  repeat the loop until some criterion is met.

So you can make a while loop into a for loop by adding an iteration statement into the loop, but it is better to just use the loop that is designed to iterate.
