<li><p><a href="https://atom.io/">Github Atom</a> er en meget god teksteditor til Python.</p>
<p>En teksteditor er et godt valg for å redigere én fil. Jeg bruker Atom til nesten alt jeg skriver av Python-kode.</p></li>
<li><p><a href="https://www.jetbrains.com/pycharm/">PyCharm</a> er et godt IDE til Python.</p>
<p>IDE-er er større og mer kompliserte enn teksteditorer. PyCharm kan være et godt valg til større prosjekter. Jeg bruker delvis PyCharm når jeg utvikler på ANDIM.</p></li>
