<DIV>Say that I have a class and I want to make 100 objects. </DIV>
<DIV>Then it could look like this:</DIV>

Chairs(object):</SPAN></DIV>

<DIV>How do I shorten this? I have thought of using a for sling. I have looked
in my programming</DIV>
<DIV>book and on the internet, but I don’t know how to make this shorter. The
arguements (“10”, “20”)</DIV>
<DIV>should be the same for every object, which should make it easier than if
they were different each
time?</DIV></DIV></DIV></DIV></DIV></DIV></DIV></BLOCKQUOTE>
<DIV> </DIV>
<DIV>If you ever write a line of code more than once, it's a good sign that you
have what's called a code smell. This example is very smelly code ;)</DIV>
<DIV> </DIV>
<DIV>What you should do instead is have a collection of chairs:</DIV>
<DIV> </DIV>
<DIV>chairs = []</DIV>
<DIV>for _ in range(100): # the underscore `_` indicates that you don't care
about the value</DIV>
<DIV> chairs.append(Chairs("10","20))</DIV>
<DIV>----------------------------------------------------------------------------------</DIV>
<DIV> </DIV>
<DIV>Yes, I got that right now. But now that you talked about shortening code, I
have a general question.</DIV>
<DIV>What if I don’t write the same line of code more than once, but I write
similiar lines more than once. Is that okay? <IMG

class="wlEmoticon wlEmoticon-smile" alt=Ler
src="cid:B397E3CA847946668FE771052495EC8E@MichaelxDator"></DIV>
<DIV> </DIV>
<DIV>For example:</DIV>
<DIV>value="green”</DIV>
<DIV>value_1=”green”</DIV>
<DIV> </DIV>
<DIV>click=-1</DIV>
<DIV>click1=-1</DIV>
<DIV>click2=-1</DIV>
<DIV> </DIV>
<DIV>I know that I can make this shorter, with a for sling for example, but the
problem is that </DIV>
<DIV>I need to use these variables later in my program, and I don’t know how do
to then, to be able</DIV>
<DIV>to use them later on, in a function for example. Do you have any general
tips on how to make</DIV>
<DIV>your code shorter?</DIV>
<DIV> </DIV>
<DIV>I also hope I have learnt to post better now.</DIV>
