I know Python, C, C++, Java, VB.NET and the basics of C# and javascript.
I actually started to learn to program in Python at university, but after I learnt Java and C, I really prefer those over Python. I find it much clearer to read and write code that has neat semicolons and curly brackets, instead of for example Python that only uses indentation to separate your code into several blocks. Also object oriented programming is only limited available in Python, while the power of Java or C++ really lies in using OOP. Using inheritance in Python with all those
__init__ statements is really horrible compared to the java approach. Also simple things like that you write the type of a variable explicitly in java or C++ (for example int i =1) compared to python (i = 1) makes it much easier to find errors when debugging your code in my opinion.
