I think choosing a language is not what matters but what matter is that in which language you are more comfortable and which language you know better. But i guess python is way more easy to operate than java , c++ or even C . I personally like to use either python or perl both are extremely easy to use compared to java and c++. Python is preferred more because it can be compiled into a executable code or even can run uncompiled. Python is way easier to understand even for beginners so choosing python over java and C++ will be a good choice.
