Yes, it doesn't matter in what module a baseclass is defined. Just go ahead
and import it:
# untested
import steamapi.user
class User(steamapi.user.User):
def __init__(self, userid=None, userurl=None):
super().__init__(userid, userurl)
# code specific to you subclass

That's the very idea of subclassing.

It depends ;) If you are planning only small adjustments it might be an
option to write a few helper functions together with the original
steamapi.user.User class and be done.
> If not, what would be a good way?
Generally speaking the Python community often favours duck-typing or
composition over inheritance. I'm not prepared to go into a lengthy
discussion over this -- if you are interested you have to try a search
engine or rely on the usual suspects ;)

Sure! But first, a couple of points that aren't specifically Python...
Firstly, you're using Google Groups. Until someone gets inside Google
and fixes up the code, it will make a mess of every post made through
it. Please use something better... either subscribe to the mailing
list and do everything through email, or access the newsgroup
comp.lang.python via a better client, or something of the sort.
Secondly, a note about verb tenses in English. You have this commit
message on the (as of 20140921) latest commit:
"""Fixed some bugs and did some GUI changes"""
And these comments in the code:
#search API
rawData =
urllib.urlopen('http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q='+encodedQuery).read()
#loads data from API into json
jsonData = json.loads(rawData)
#extracts the results from API
searchResults = jsonData['responseData']['results']
The more normal way to write these would be in present tense, in a
more imperative style: "Fix some bugs", "Load data", "Extract
results". (Although these comments are actually quite redundant - all
they do is tell you what the single next line of code does.) You may
also notice that the camelCase variable names you're using are in
stark contrast to the rest of the language. It's normal to use
lower_case_with_underscores instead.
Now, let's have a look at the code itself.
query = queryVar.get()
... and further down ...
global queryVar
queryVar = StringVar()
You don't need to say "global" at top level. Everything at top-level
is global. However, I generally like to, as much as possible, define
things higher in the file than their usages - so that as you read the
file, the first reference to anything is the one that tells you what
it is. That may not be practical here, but it's something to keep in
mind. (This is why import statements generally go at the top of the
file, for instance.) The language doesn't require it, but it does make
the code easier for a human to read.
links = []
for result in searchResults:
#loops through the searchResults data to find the title and
URL of the pages
#and then add the links to the links list
title = result['title']
link = result['url']
links.append(link)
print links
You're not doing anything with the title, so what you have here is a
loop that builds up a list from empty, by repeated appends. That's a
perfect job for a list comprehension:
links = [result['url'] for result in searchResults]
I'm not sure why you print the links to stdout there - is that some
left-over debugging code?
Although, the only thing you do with the list of URLs is to iterate
over it, once. You could simply merge the two loops into one:
for result in searchResults:
url = result['url']
pageData = urllib.urlopen(url).read()
... etc ...
Your text insertion is a little inconsistent: you put the URL and
title at the cursor position, then the body at the end. Is that
intentional? If so, that deserves a comment - which would be much more
useful than the comments that say what we can read in the code
already.
textDisplay.insert(INSERT, 'This spider searches for information on
your query and will display it here!')
You haven't written a spider here :) You're just calling on Google's
spider and showing some information. Similarly, the verb "CRAWL" on
your button isn't really accurate - and isn't particularly helpful to
the user either. I'd just word it in terms of how the user will value
it, and say "Search" on the button. Keep it simple.
queryWidgit = Entry(frame, textvariable=queryVar, fg='Blue', bd=5, width=50)
It's normally "Widget", not "Widgit". Not significant, but you seem to
have consistently used two i's, including in your comments.
Well, you asked for feedback. That's normally going to consist of
people pointing out where they think you did badly. But ultimately,
this is all relatively minor, so if the program works, consider
yourself to have broadly succeeded.

What do you mean, "Inheritance from API"? You can't inherit from an API,
only from classes.

I would do something like this:
# untested
def make_user(ID):
steamapi.core.APIConnection(api_key = KEY)
return steamapi.user.SteamUser(76561197996416028)
usr = make_user("X")
No need for inheritance. make_user returns an actual SteamUser instance, not
some subclass.

Class Inheritance from different module
I have the following structure:
Third-party API installed via pip:
steamapi /
app.py
consts.py
core.py
users.py
[...]
My script:
test.py
In the API, the module users.py has a class 'SteamUser' and I want to mimic
it's usage on my code, like this:
import steamapi
[...]
class User(Inheritance from API):
def __init__(self, ID):
steamapi.core.APIConnection(api_key = KEY)
super( " Inheritance SteamUser" (ID)) # creates the user using the API
[...]
So that in my code when I need to create a new user, I just call 'usr =
User("XXX")' instead of calling 'usr =
steamapi.user.SteamUser(76561197996416028)', is that possible? And of
course, I want to have access to all the class methods like 'name',
'country_code', 'time_created', 'avatar', 'friends' and so on. And finally,
is that a good approach, pythonic? If not, what would be a good way?

You don't need to write your own function, just use the relevant string and
bytes methods. Use the ljust and rjust (left and right justify) methods:
To add padding on the left, justify on the right, and vise versa:
py> "Hello".ljust(20, "\x0f")
'Hello\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f'
py> "Hello".rjust(20, "\x0f")
'\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0fHello'
(The default fill character is space.)
The same works for bytes, except you have to make sure your fill char is
also a byte:
py> b"Hello".rjust(20, b"\x0f")
b'\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0fHello'
py> b"Hello".ljust(20, b"\x0f")
b'Hello\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f\x0f'
