Python Easy To Code
IF you can install the required modules
I was thinking to myself tonight here at 1AM wondering why do I hate Python sometimes and dread using it? Why does nothing work in Python and why can I Google a million errors I’m having and find others are having them to? What does this remind me of ?
Is it Java? No, nothing is as bad as Java, but does anyone still know what PERL is? It was a contender under PHP blew it out of the water. The reason being that PHP was simple to setup for the most part. It wasn’t so difficult to get modules for MySQL and other things.
Now, granted Python has a lot more functionality and flexibility than virtually any language but this is where in a bad way it has more in common with PERL and it’s evil CPAN.
I’ve spent more time troubleshooting the Python environment than the actual coding. Coding is not the hard part, it’s wondering in which OS and version of Python, PIP, setuptools etc.. are going to let everything work. Or will you accidentally break Python in the process?
#even with fabric installed it doesn’t have the python module
Traceback (most recent call last):
File “./cpub.py”, line 14, in <module>
from fabric import network
ImportError: No module named ‘fabric’
I’m sure a lot of people will read this and say “the above looks like a n00b mistake” but alas I have tried installing fabric in fact I installed Version 1, 2 and 3 and neither combination has fixed anything.
Here is some random output while being in the process of trying to resolve the import error from fabric. Keep in mind this is one example only, I’ve run into this sort of endless thing on virtually any Python script you find on Github. This is too PERL like and if anything “too Linux package like” where you find that sometimes certain packages won’t work or are incompatible. Python really just needs a simple standardized API like real programming languages whether we are talking C, C++, C# etc…
