I agree it can be very variable in quality.
One of the problems of Open Source is that there are more 
people who want to write code than there are who want to 
write documentation...

All non standard items, all Open Source.

All standard items for Browser work. Tools designed for the job.
Have you tried using non standard browser code libraries 
like say the various graphing libraries for JavaScript? Or 
sound libraries, say? They are just as patchy in support.

Exactly, but they are standard tools so need to be 
compared to core Python not the contributed software.
Of course you could use Java on the server and then 
you could buy commercial libraries that do the same 
job as Numpy etc. But you have to pay hard $$$ for 
those. So you take your choice: persevere with Python 
and its libraries for its rapid development and hope the 
time savings outweigh the time spent working out how 
the libraries work or, pay out for the commercial products 
and hope the savings in quality(*) outweigh the 
expenditure. And also hope that the different tools work 
together because if they don't you can't go look at 
the source to fix it! Its all about making choices, but 
that's engineering - you choose the right trade off!

(*)And of course that's a gamble too because there are 
many badly documented commercial libraries too! 
But at least you can complain to somebody! :-/
