I added the b because the default in the definition of read_csv is b'.', but 
you are right, it works with just ','.

RE: Unable to start Python with Windows 7

2019-09-23 Thread cdoare.ext
Hi Eren,
I have Win 64bit and run Python also in 64 bits.
What is strange is that I can run Python, but only with a short program !
Best regards,

Hi Crhistian,
hard to tell, what might help is if you can copy/paste code which does
not run (an example should be as small as possible).
In addition, isn't there any output you get when the program doesn't run?
A traceback etc... and how do you run those programs, by double clicking
.py files via cmd like python myfile.py, via an editor ...

How to get only valid python package index

2019-09-23 Thread Vijay Kumar Kamannavar
Hellom

As per https://pypi.org/simple/ we have ~2,00,000 packages. i feel there
are lot of packages found to be dummy/Experimental. Where can we get the
properly maintained package list for python?

If not, atleast please let me know what kind of strategy i shoud use to
decide whether package is valid or not?



Thanks,

Vijay

There is no "properly maintained package list" in the sense that I
suspect you mean it, i.e. a curated list where the maintainers
guarantee a particular level of quality or support for the available
packages. PyPI is an open index and anyone can register an account and
upload packages, without restriction.

> If not, atleast please let me know what kind of strategy i shoud use to

The responsibility for reviewing and assessing the quality of packages
lies with the user, so you'll need to assess each package for
yourself, in much the same way that you would assess any other open
source package - you can look at existing code, blog posts or articles
to get a sense of what packages are considered good, or "best of
breed", or you can assess the code and documentation against whatever
standards you wish to apply. It shouldn't take long if you read some
articles to get a sense of some of the more well-known packages
(things like requests, numpy, pandas, matplotlib, django, ...) but
what is best for you depends entirely on what you are trying to do
with Python.

Hope this helps,
Paul

python installation.

I receive a 'not a valid Win32...' after a few minutes of installing python

Are you using the appropriate installer? In particular (guessing from 
the message) might you have fetched a 32 bit install instead of the 
x86-64 installer?


Please check this page:

 https://www.python.org/downloads/windows/

for installers, and if you've definitely got the right installer please 
post details about what installer you chose.

I used Windows x86-64 executable installer the first two times and Windows
x86-64 web-based installer. They both yielded the same result.

In addition of what Paul already wrote:
"https://pypi.org/simple"; is an interface for programs
(such as "pip" or "buildout") not for human users.
Use "pypi.org" directly for an interface for humans.

"pypi.org" allows you to filter by "classifier".
There are many kinds of "classifier"s, among them "Development Status".
It allows you to restrict searches to "stable" releases
(to exclude e.g. "experimental" versions).
You can also take into account the version number. Often, an "a" (= "Alpha")
or "b" (= "Beta") in the version number indicates, that the author
does not yet consider the version fully/reliably/generally operational.

As Paul pointed out: all information on "PyPI" is provided by
the authors and, therefore, is not necessarily reliable.
That said, I have met only isolated packages which were not usable
(according to my standards - which may be very different from yours).
