I started a new chapter in Automate Boring Stuff with Python called Web Scraping ( and I'm planning to focus on this field so if you have any other useful link you're welcome to share ) but since the start I'm facing an obstacle.
When I run the first code with Python IDLE
import webbrowser
webbrowser.open('http://inventwithpython.com/') it opens web page pretty fast but when I write a code in notepad++ and try to start a created file in command prompt I receive an error:
Error:

if shutil.which(browser):
AttributeError: module 'shutil' has no attribute 'which'
Not sure what's going on here...
I don't know what you are doing, it works when I try it.
"which" was added to "shutil" in python 3.3.
So somewhere you are really running python 3.2 or less, not python3.6
Check if you have named a file
shutil.py,if you have rename it.
How it shall look.
λ ptpython
>>> import shutil
>>> shutil.__file__
'c:\\python36\\lib\\shutil.py'
>>> shutil.which
<function which at 0x036F5E40>
>>> help(shutil.which)
Help on function which in module shutil:
which(cmd, mode=1, path=None)
Given a command, mode, and a PATH string, return the path which
conforms to the given mode on the PATH, or None if there is no such
file.
`mode` defaults to os.F_OK | os.X_OK. `path` defaults to the result
of os.environ.get("PATH"), or can be overridden with a custom search
path.
Bingo! After removing shutil.py it works fine.
Thank you for the link, will take a closer look.
regarding webbrowser module it opens web sites with Internet Explorer browser. Any idea how to change that to Firefox or any other browser just not this obsolete one?
you can see available browsers with
webbrowser._tryorder and the order it will try to open them in
>>> import webbrowser as wb
>>> wb._tryorder
['xdg-open', 'gvfs-open', 'x-www-browser', 'firefox', 'google-chrome']
>>> wb.get('firefox').open('https://www.google.com')Im not too sure about windows but you may have to register it?
import webbrowser
ffpath = 'C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe'
print(webbrowser._tryorder)
webbrowser.register('firefox', None, webbrowser.BackgroundBrowser(ffpath), 1)
print(webbrowser._tryorder)
ff = webbrowser.get('firefox')
ff.open("http://www.google.com")

Think the simplest way on Windows is to change
default browser in Windows 10.
>>> import webbrowser
>>> webbrowser._tryorder
['windows-default', 'C:\\Program Files (x86)\\Internet Explorer\\IEXPLORE.EXE']
If windows-default is set to Chrome then webbrowser open in Chrome.

webbrowser.register('firefox', None, webbrowser.BackgroundBrowser(ffpath), 1)
print(webbrowser._tryorder)
ff = webbrowser.get('firefox')
ff.open("http://www.google.com")
this is what I get
Error:

NameError: name 'ffpath' is not defined
I practise Python on old laptop that has Windows 7. What I did is that I made Firefox a default browser through itself - Tools > Options. It's a simplier option, but I wanted to know is it possible to change a browser through a code.
