You are using pip version 7.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

I don’t wish to challenge Malcolm’s assertion, but from personal experience I think it’s a really bad idea to pip2 or
pip3 install as root as it doesn’t play nicely with package managers (e.g. zypper). For this reason I would only over
pip install this way:


sh-4.3$ pip3 install --user <package>

… to install to ~/.local/

If you really need to pip install a package as root, then I suspect that’s a symptom of a developer environment that
has not been properly thought through.

Hi
@flymail never use pip… always build rpms :wink:

@dilbertone, use the rpm?

https://software.opensuse.org/search?utf8=✓&q=beautifulsoup4&search_devel=false&search_devel=true&search_unsupported=false&baseproject=ALL

Since it looks like you want python3, then it would be;
https://software.opensuse.org/package/python3-beautifulsoup4

Haha! Good answer. For some libraries, however, this isn’t the most practical option (e.g. Google TensorFlow).

Hi
Doesn’t look too bad to build… if I had a Nvidia card to use… install the docker image :wink:

About 10 years ago now was building some nuclear molecular software as an rpm… compile time was around 15 hours… esp frustrating when would get hours in and then hit an error to fix… :frowning:

First, if an RPM is available and sufficient, then it’s probably the easiest way to install.

As for your attempts at installing from PyPi,

  • You should have followed the instructions in your error and upgraded pip. That can be done safely installing to your system defaults, you shouldn’t have to worry about conflicts of any type.

You are using pip version 7.1.2, however version 9.0.1 is available.
You should consider upgrading via the ‘pip install --upgrade pip’ command.

You may wish to isolate your installs, and perhaps even run different versions of Python side by side on your system. To do that, the traditional way is to install and use virtualenv. Otherwise, of course you can use virtualization to run different machines which can be customized however you wish. Installing your python app to a user directory as flymail describes is not always an option, the application may still require elevated permissions to run or code may assume a different install location.

hello dear malcolm, flymail and Tsu

many many thanks for the replies and the tipps.

i did the following :

to test all - and to do some first steps i tried to run the following code;


import urllib
from bs4 import BeautifulSoup
import urlparse
import mechanize


# Set the startingpoint for the spider and initialize 
# the a mechanize browser object
url = "http://sparkbrowser.com"
br = mechanize.Browser()

# create lists for the urls in que and visited urls
urls = 
visited = 


# Since the amount of urls in the list is dynamic
#   we just let the spider go until some last url didn't
#   have new ones on the webpage
while len(urls)>0:
    try:
        br.open(urls[0])
        urls.pop(0)
        for link in br.links():
            newurl =  urlparse.urljoin(link.base_url,link.url)
            #print newurl
            if newurl not in visited and url in newurl:
                visited.append(newurl)
                urls.append(newurl)
                print newurl
    except:
        print "error"
        urls.pop(0)

i get the following lines back


martin@linux-3645:~/dev/python> python p1.py
Traceback (most recent call last):
File "p1.py", line 3, in <module>
from bs4 import BeautifulSoup
ImportError: No module named bs4
martin@linux-3645:~/dev/python>

well i am not very sure what happened - probably i have installed the bs4 on the wrong path -

note - i am running python 3.
surely - i have to rewrite the above mentioned code to python 3 -

but the main thing i wonder - is why i get the errormessages…

how to check if i have installed bs4 corrrectly?

OK so you’ve gone ahead and have installed using pip as user rather than installing an RPM as root.

Looking at you’re code, I’m not convinced you’re running Python 3 because `print newurl’ would emit a syntax error
before the import error you are seeing. Please try and run your code like this:


$ python3 p1.py

… if you get the same import error then you’re going to have to repost your code.

12

hello dear Flymail,

many thanks for the answer -

see here the output:


martin@linux-3645:~/dev/python>  python3 p1.py
  File "p1.py", line 31
    print newurl
               ^
SyntaxError: Missing parentheses in call to 'print'
martin@linux-3645:~/dev/python>

love to hear from you

13

well i guess that i runned in some conflicts

Since opensuse comes with Python 2 and Python 3 preinstalled, we need to specify which version we are using.
If i have had installed an additional Python version, (say 3.6.3) we need to reference that, for example pip3.6 install …

how to check and make sure what is going on on the machine!?

OK this proves you were previously testing p1.py using Python 2, yet it’s clear from the pip install output that
installed Beautiful Soup for Python3. Since your test program is written in Python 2 in a way that isn’t compatible with
Python 3, then you are bound the end up with problems. Rather than using a test program you can simply test whether the
Beautiful Soup package installed correctly from Python 3 console:


$ python3
>>> from bs4 import BeautifulSoup
>>> exit()

If the above import works without error then you installed BeautifulSoup correctly for Python 3.

But stepping back a bit, your approach seems have a few problems:

  1. You installed a pip package as user when it would most efficiently be done using a prebuilt RPM as root.
  2. You were convinced you were using Python 3 when you in fact you were using Python 2 (the openSUSE default).
  3. You do not seem to detect the differences in Python 2 and Python 3 syntax (they are different languages).

So you need to ask yourself some fundamental questions:

  1. Are you coding in Python 2 or 3?
  2. If you’re coding in Python 3, how much of any Python 2 code you use/have written need to be converted to Python 3?
    3, If you’re installing packages, is there is any benefit doing it on a per-user basis (which is what pip install as
    user does) especially since it will be more cumbersome to maintain during version upgrades compared to using a pre-built
    RPM installing as root (which upgrades automatically during a relevant zypper up)?

These questions, only you can answer. But you should do so before worrying too much about Beautiful Soup.

dear flymail.

first of all - many thanks for the answer:
hope i got you right - and that i have gathered all the important information.

well i have python 3 on the machine…

i start to code in Python.

while using python 2 scripts we can do so if we call explicit “python2” or “python3”

now i try to find out what is the best way to keep pyton up to date - and how to instiall new modules /plugins

**NotE: **i use eric 5

Pleasure, but please answer my questions. Did this work:


$ python3

>>> exit()

You will see that Beautiful Soup is not listed there because rather that installing the RPM as root, you installed as a
pip package as user. Why don’t you just do this:


$ su -
# zypper in python-beautifulsoup4 python3-beautifulsoup4
# exit

i start to code in Python.

Ahh okay, beginner - no problem. You might want to read: Python2orPython3 - Python Wiki

while using python 2 scripts we can do so if we call explicit “python2”
or “python3”

Good idea. I think it is slightly shameful that the openSUSE default is still python2, especially since the YaST
shouldn’t care (since it is written in Ruby). Remember that even if you install a package for one version, you have to
also install it for the other (as the `zypper’ call above does).

> now i try to find out what is the best way to keep pyton up to date -

Since you’re a beginner I’m going to say it: use Python 3 and forget Python 2. Sure, there might be a small handful of
packages that are Python-2 only, but if they still are at this stage they are probably not worth using. If you are
using old Python 2 code, convert it: you can do it either manually or use 2to3:
25.4. 2to3 - Automated Python 2 to 3 code translation — Python 2.7.18 documentation .

> *NotE: *i use eric 5

If you’re a beginner, I would advise against an IDE like eric 5 because they hide a lot of what is going on in the
background. You might want to read Learn Python the Hard Way . If you’re not familiar with Vim
or emacs, I would advise using kate (in KDE) or gedit (in GNOME). In any case, you will want to run Python from console
but bear in mind within a Python shell, versions 2 and 3 have different ways of executing Python scripts:


$ python2
>>> execfile("yourscript.py")
>>> exit()
$ python3
>>> exec(open("yourscript.py").read())
>>> exit()

HTH.

So far so good: many thanks der buddy for the continued help:

after having done this - i tried out my new installation while

**Using python requests module to login on an Wordpress based website
**

**what happened: **I’m trying to login to a Wordpress based website using python’s request module and beautifulsoup4.
It seems like the code fails to sucessfully login. Also, there is no csrf token on the website. How do I sucessfully login to the website?


import requests
import bs4 as bs
with requests.session() as c:
    link="https://gpldl.com/sign-in/" #link of the webpage to be logged in
    initial=c.get(link) #passing the get request
    login_data={"log":"*****","pwd":"******"} #the login data from any account on the site. Stars must be replaced with username and password
    page_login=c.post(link, data=login_data) #posting the login data into the link
    print(page_login) #checking status of requested page
    page=c.get("https://gpldl.com/my-gpldl-account/") #requesting source code of logged in page
    good_data = bs.BeautifulSoup(page.content, "lxml") #parsing it with BS4
    print(good_data.title) #printing this gives the title that is got from the page when accessed from an logged-out account

i got back:

martin@linux-3645:~/dev/python> python w1.py
Traceback (most recent call last):
  File "w1.py", line 1, in <module>
    import requests
ImportError: No module named requests

well: Requests is not a built in module (does not come with the default python installation), so you will have to install it:
OSX/Linux

i used this command:

Use $ sudo pip install requests

if we have pip installed

Alternatively we can also use

 sudo easy_install -U requests

if we have easy_install installed.


martin@linux-3645:~/dev/python> sudo pip install requests
Requirement already satisfied: requests in /usr/lib/python3.4/site-packages
martin@linux-3645:~/dev/python>

btw - see this …:

martin@linux-3645:~/dev/python> sudo pip install requests 
Requirement already satisfied: requests in /usr/lib/python3.4/site-packages 
martin@linux-3645:~/dev/python>

so what can i do now? - i thnk that i will open a new thread - since this is a new topic…
