C vs Python Speed Test #cpp #python #programming #code

In this video, we are going to do a Python vs C Speed Test.

🧑🏻‍💻 My AI and Computer Vision Courses⭐:

💵Channel Member for help with projects, private discord, and exclusive perks:

I'll be doing other tutorials alongside this one, where we are going to use C++ for Algorithms and Data Structures, and Artificial Intelligence. The purpose of this tutorial and channel is to build an online coding library where different programming languages and computer science topics are stored in the YouTube cloud in one place.

Feel free to comment if you have any questions about the things I'm going over in the video or just in general, and remember to subscribe to the channel to help me grow and make more videos in the future. :)

Well you can actually optimize python a lot by putting a few zeros at the end of
number += 1

[WhyNotProgram]

Gotta love seeing the potential of languages! But we can never get too caught up in speed. It’s always about the right tool for the right job

[elirol]

The comparison was made between C and Python, not C++ and Python.

[jorgheinecke]

If somebody believe Python can run faster than C++. He or she doesn't understand software development.

Compilers skip useless loops. Use the iteration to do an operation for example to print and then compare them. We don't write useless for loops

[omhosjo]

C++ for fast run like it but python very good for internet manipulation and settings

[luisafonso]

You could use a jit compiler in python, then the results would be probably way closer

[medio_cre]

I compared JS and Python with the same code example and JS just humiliated Python with the same speed as C!

[AB-cdgd]

Switched part of my softwares from python to golang with dll and the speed difference was insaneee

[_Bernardo]

Could you please make a video with for loops alternatives in python?
It seems hard to avoid them in some OpenCV applications but im not sure what would be an alternative other than just run OpenCV with C++

[starpawsy]

Now let's see a comparison with Perl, and with hand-optimised assembler.

[opus_X]

You said you were gonna use c++ but you used C. Or do they both have the exact same compile and runtime?

[nastykerb]

Me, a gentoo user :"where is the optimization flags"

Just spin wait alone is not a good test. The best test is finding data a large file. Surprisingly, the differences between languages will be smaller, probably much smaller. Unless, C/C++ code uses special bare metal tricks to speed up memory access.

[noddle]

C++ is 20x faster at this activity*. It varies a lot depending on what you’re doing, C++ is more like 4-40 times faster depending on varying circumstances.

[abcdxcxd]

these programs are not the same unless an integer multi precision library for the number increment is used.

[yudhobaskoro]

Wait, why don't you just put number=i, since i is already counted just use i as number ?

[gameworld]

А еще в новых версиях c++ есть возможность указать компилятору что const переменная может посчитаться во время компиляции

[KyyTyy]

Should use c or c++ for creating artificial neural network, not python.

[SameAsAnyOtherStranger]

This video is dated 18 days after the release of Python 3.11 which is supposed to be much faster than previous releases. Is that the version you're running here?
