Cython Tutorial - Bridging between Python and C/C++ for performance gains
Why Stack Overflow recommends it
Stack Overflow users link it as a hands-on walkthrough of Cython setup and the speedups it can give over pure Python loops.

What it is
A roughly 30-minute sentdex tutorial introducing Cython, a superset of Python that adds typing information and compiles to C extensions. It walks through setup, building with setup.py, and benchmarking a loop against plain Python.

I downloaded Cython and followed the instructions found here: [LINK] I have the MinGW compiler already I am using python3 not python2, but according to this video ( [this video] ) it looks like one can just use python 3. Anyways, when I try to do the command python setup.py build_ext --inplace (unlike in the video, one must write python instead of python3, otherwise it won't even start to run), I get the error message below: Traceback (most recent call last): File "setup.py", line 4, in <module> setup(ext_modules = cythonize('cython_example.pyx')) File "C:\Program Files\Python37\lib\distutils\core.py", line 148, in setup dist.run_commands() File "C:\Program Files\Python37\lib\distutils\dist.py",

The things that you may try are: Search for optimization in Python. (Using python builtins might help!) Generally list comprehensions are better than for loops My general advice is to use list comprehension with Cython . First utilize the list comprehension, and then check for Cython optimizations with the .pyx files and cythonize it. Cython, in general, translates the python code to the C. Especially loops in Python works significantly faster with Cython. You can check one of the Sentdex's video [this video] explaining the general principles for cython. As you could see in the 23:20 of the video, it makes a significant change like ~100x faster than the traditional python loop.
Cites ImpulsePenny · 2021-04 · Stack Overflow · on “Exception has occurred: ModuleNotFoundError”
I am trying to learn Cython at the moment and have followed a tutorial here [this video] . I have it working within Ubuntu (on vmware) but right now I am trying to get it working on windows (using VSCode). I took all the files that I had created in Ubuntu and put them on my machine. When I try to run my python file testing.py I receive this error: Exception has occurred: ModuleNotFoundError No module named 'example_cy' here is the code for the testing.py import timeit cy = timeit.timeit('example_cy.test(5000)', setup = 'import example_cy', number = 1000) py = timeit.timeit('example_py.test(5000)', setup = 'import example_py', number = 1000) print(cy, py) print('Cython is {}x faster'.format(py/cy)
