Python is an excellent language, but given that it’s free, it also comes with a lot of conspicuous loose-ends that you will not expect in commercially supported platforms like MATLAB.
Don’t expect everything to work right out of the box in Python. Everything is like 98% there, with the last 2% frustrate the heck out of you when you are rushing to get from point A to point B and you have to iron out a few dozen kinks before you can really start working.
When I tried use pyinstaller (v3.4) to compile my Python (v3.7) program into an executable, I ended up having to jump through a bunch of hoops:
pip install pyinstallergives:ModuleNotFoundError: No module named 'cffi'
- Then I looked up and installed cffi
pip install cffi
- After the dependency was addressed manually (it shouldn’t )
pip install pyinstallerworked - Then I tried to compile my first Python executable with pyinstaller, and I got this exception:
File "C:\Python37\lib\site-packages\win32ctypes\core\cffi\_advapi32.py", line 198 ^ SyntaxError: invalid syntax - I searched the exact string and learned that pyinstaller (v3.4) is not ready for Python 3.7 yet! How come pip installer didn’t check for it? I opened up the offending file and looked for line 198 and saw this:
c_creds.CredentialBlobSize = \ ffi.sizeof(blob_data) - ffi.sizeof('wchar_t')It’s a freaking line continuation character
\(actually the extraneous CR before CRLF) that rooster-blocked it. - I just deleted the line continuation and merged the two lines, and saved
_advapi32.py, then I was able to compile my Python v3.7 code (using pyinstaller 3.4) with no issues.
This is not something you’ll experience as a MATLAB user. The same company, TMW, wrote the MATLAB compiler as well as the rest. The toolbox/packages are released together in one piece so breaking changes that causes failure for the most obvious use case are caught before they get out of the door.
Another example of breaking changes that I ran into: ipdb does not allow you to move cursor backward.
Again, this is the cost associated with free software and access to the latest updates and new features without waiting for April/October (it’s the MATLAB regular release cycle). If hassle and the extra engineering time far exceed licensing MATLAB licensing costs, MATLAB is a better choice, especially if software is just a chore to get your company from point A to point B, and you are willing to pay big bucks to get there quickly and reliably.
Even with free software on the table, your platform choice is always determined by:
- how much your time is worth wrestling problems
- how much flexibility do you need (for customizing to your needs)
- how much you are willing to pay for the licenses and support
In any case, Python community did good work. Please consider sponsoring PyInstaller and PSF if you profit immensely from their work. But if your company already paid for MATLAB and has real MATLAB experts on it*, don’t switch completely to Python just for the sake of chasing the trendy thing. You will loose time. Lots of time! Precious engineering hours! Over really stupid things like the ones above that is totally not your fault! It’s better to dedicate a few days dealing with MATLAB-Python interface than wasting months over the clumsiness of Python if you have a long, complex workflow
Python’s largest value over MATLAB is that there’s a function developed for nearly every less than common situations (like all different variations of path and file management tools) so you don’t need MATLAB File Exchange to fill in the gap, but the downside is that Python, just like the rest of FOSS world (or Tektronix), has absolutely no sense of user experience studies: common operations are tucked under clumsy maneuvers such as making user jump through hoops to run a Python script in the interpreter:import do not execute the script after its cached, execfile was lile eval in MATLAB so they made it hell, or you need to import a library like runpy or runfile to do something basic like this. Why can’t they just add a native root-level function like runfile() and call it a day without waiting for IPhyton to provide something this basic? I know Python was is too eager to protect the namespace, but this comes at the expense of adding a lot of stupid maneuvers for really basic bread-and-butter stuff). Python is productive in the sense that there are many sophisticated features that are readily available that you don’t have to write your own library for the advanced cases, but the edge is like 1% of the use cases which I invest the time when I run into it: it’s not worth making 99% of my workflow miserable!
* Many people those who claimed decades of MATLAB under the belt didn’t really learn the advanced concepts through studying documentation, MATLAB blogs or get training to take it to the next level of super-productivity! You can tell if they have a lot of for-loops in situations that don’t absolutely need it (memory saving, injecting elements to LHS assignment, parallel computing, not loading too many files at the same time, drawing graphics (order matters), big tasks that needs to be resumed if it throws an error) and using cells everywhere when they should have used structs or more modern types (heterogeneous data structures) such as table(). Most of the modern, super-productive MATLAB language constructs happens since 2013, so I can safely say that MATLAB experiences accumulated before that aren’t too valuable for developing business logic part of the code (might be useful if you are writing tools and lower level MATLAB code like those in TMW).
