Hello,

I have a syntax error, below here, the code and the error are there.

I am using Spyder3 as IDE with Python 3.5.2 and Ubuntu 16.10, all packages are up to date …

Only for a completion … But I don’t understand why there are a syntax error with 3 if-Statements all working fine!

What is my failure? Please help me! Thank you very much!

The best greetings:

Jakob Krieger
