can you really call python programming though? The reason why python is so quick to write is because its so-called libraries are pre-compiled C programs. so you're not writing new programs, you're scripting existing ones.
My indirect experience with python is that it is slow as hell. Anytime I install an app that includes python it lags 15-30 minutes on that step. Anytime I'm asked to install something with conda it takes 30 minutes to an hour.
I'm sure that is just due to environmental and implementation issues, but the Java fans say the same thing...
