In some cases with some tricky programming, Python can be faster than Java

But I assume he meant speed of development.

Well, compiled python is certainly faster than C++.

Source?

I don't actually use C++ that much, but when I do, it takes forever to do anything.

Quick note: "I've read it in numerous places" != Source.

A source would be a link supporting your position, i.e. http://furryland.org/~mikec/bench/, which shows that Python is *NOT* faster than C++.



You're doing it wrong.

Python
Python is an astonishingly friendly scripting language. Check this out: I once wrote the same game twice, once in python then once again in C++. The python implementation was completed 7.4x as fast as the C++ version. By my calculation, using python has allowed me to make my games 7.4 times better than they otherwise would have been. Either that, or I'd have finished them in 1/7.4=0.135etc the time. And I used python to figure that out. Incredible!

I also probably am doing it wrong. I'm going to assume you mean optimized C++ code written by an expert is faster than python code.

I know very few people who'd rather develop in C or C++ instead of Python, Java, C#, Haskell, PHP, Ruby etc - and even then it's usually because they're very much more familiar with C or C++ the other languages.

No, absolutely not. For one, there aren't any Python compilers that aren't just proof of concepts (as in, that actually work beyond 1 or 2 packages). Second, Python is an *interpreted* language. The interpreter is most commonly CPython (the official implementation of python - the one from python.org), which is written in C. Now tell me, how is a language interpreted by a C runtime going to *EVER* be faster than just writing in C/C++? The answer, of course, is NEVER. Python can *NEVER* be faster than C/C++ assuming a competent programmer.

No, you haven't. You probably misread and they said speed of development, or they are completely retarded. Also, please provide some semblance of an example of when you used C++ and it was slow.

An expert in Python couldn't keep up with a rookie in C++. C++ is wicked fast. Very few languages are faster by any significant amount. Hand coded assembly is pretty much the next step if you want more speed.

I happen to like C/C++, as do a couple of my friends. I prefer coding in Python, followed by C++, followed by C#.

No. Take a look here for the difference between interpreted and compiled languages.

The C++ coder.

:facepalm: C++ is pretty easy to learn; it just takes more steps to do what you want as it is a lower level (and thus more powerful) than Python, which is a very high level language (Read This and This)

If you're correct, wouldn't C++ have to be interpreted too, putting them on the same level? I referred to C++, not C.

Compiling a basic application using the openGL library. Very basic. It was just to render a few images at a time, but it didn't behave very well. I can try and find the files if you want to see.

Let's say you coded something in python, and I attempted something in C++. Assuming I actually finish my project, who's is going to be faster?

I'm sorry, maybe it's just the learning curve that's getting to me, but I am actually afraid of C++ now. I worry that if I keep VC++2005 installed on my computer for too long, it will kill me in my sleep.

Compiling is *NOT* running. Compiling C++ is slower than Python because you NEVER COMPILE PYTHON.

Get it through your head. C++ is compiled, Python is *NOT* compiled. Python is *NEVER* compiled

And I promise you, a C++ OpenGL application is *NEVER* slower than a comparable Python OpenGL application. If it was, games would be written in Python. They aren't. Games are usually written in C++.
