Mike Callahan

This is a good course, the teacher is very knowledgeable about PyCharm. I have been messing with this, asked questions he doesn't address in the course and he gets right back to me. VERY helpful, caring guy who just wants you to succeed.

Ich fand es besonders hilfreich, dass der Author langsam englisch spricht und außerdem der Text geschrieben erscheint. So ist es sehr verständlich und so wünsche ich es mir für andere Kurse.
