There's a simple answer to this one too: Java is faster than Python because it's a compiled language. ... Python also boots up more quickly. But yes, in general, Java runs faster - and if that matters to you then Java may just be the first programming language you decide to learn.
Is it better to learn Java or Python first?
If you're just interested in programming and want to dip your feet in without going all the way, learn Python for its easier to learn syntax. If you plan to pursue computer science/engineering, I would recommend Java first because it helps you understand the inner workings of programming as well.
Which is easier to learn Java or Python?
There is more experimentation than production code. Java is a statically typed and compiled language, and Python is a dynamically typed and interpreted language. This single difference makes Java faster at runtime and easier to debug, but Python is easier to use and easier to read.
