If you do not provide the root argument there is still an implicit
dependency:
"""
class Font:
...
def __init__(self, root=None, font=None, name=None, exists=False,
**options):
if not root:
root = tkinter._default_root
tk = getattr(root, 'tk', root)
"""
>>> import tkinter
>>> from tkinter import font
>>> font.Font(family="Helpvetica", size=10, weight="bold")
Traceback (most recent call last):
File "", line 1, in
File "/usr/lib/python3.4/tkinter/font.py", line 93, in __init__
tk.call("font", "create", self.name, *font)
AttributeError: 'NoneType' object has no attribute 'call'
>>> root = tkinter.Tk()
>>> font.Font(family="Helpvetica", size=10, weight="bold")
So you have to create the main window before you can create a Font.

Help debugging code - Negative lookahead problem
Hi everyone,
So here is my problem. I have a bunch of tweets and various metadata that I
want to analyze for sociolinguistic purposes. In order to do this, I'm trying
to infer users' ages thanks to the information they provide in their bio, among
others. For that I'm using regular expressions to match a couple of recurring
patterns in users' bio, like a user mentioning a number followed by various
spellings of "years old" as in:
"John, 30 years old, engineer."
The reason why I'm using regexes for this is that there are actually very few
ways people use to mention there age on Twitter, so just three or four regexes
would allow me to infer the age of most users in my dataset. However, in this
case I also want to check for what comes after "years old", as many people
mention their children's age, and I don't want this to be incorrectly
associated to the user's age, as in:
"John, father of a 12 year old kid, engineer"
So cases as the one above should be ignored, so that I can only keep users for
whom a valid age can be inferred.
My program looks like this:
import csv
import re
with open("test_corpus.csv") as corpus:
corpus_read = csv.reader(corpus, delimiter=",")
for row in corpus_read:
if re.findall(r"\d{2}\s?(?=years old\s?|yo\s?|yr old\s?|y o\s?|yrs
old\s?|year old\s?(?!son|daughter|kid|child))",row[5].lower()):
age = re.findall(r"\d{2}\s?",row[5].lower())
for i in age:
print(i)
The program seems to work in some cases, but in the small test file I created
to try it out, it incorrectly matches the age mentioned in the string "I have a
12 yo son", and returns 12 as a matched age, which I don't want it to. I'm
guessing this has something to do with brackets or delimiters at some point in
the program, but I spent a few days on it, and I could not find anything
helpful around here or on other forums, so any help would be appreciated.
Thus, the actual question is: how to make the program not recognize 12 in
"John, father of a 12 year old kid, engineer" as the age of the user, based on
the program I already have?
I am somewhat new at programming, so apologies if I forgot to mention something
important, do not hesitate to tell me if you need more details.
Thanks in advance for any help you could provide!

Remove some of the alternatives and it should become clearer:
r"\d{2}\s?(?=years old\s?|year old\s?(?!son|daughter|kid|child))"
The negative lookahead is in the last alternative and applies only to
that one.
Adding a non-capture group (?:...) around the alternatives:
r"\d{2}\s?(?=(?:years old\s?|yo\s?|yr old\s?|y o\s?|yrs old\s?|year
old\s?)(?!son|daughter|kid|child))"
Another point: the \d{2} will match only 2 digits and there's nothing to
prevent it from matching the end of a series of digits, so but if the
person was, say, 101 years old, it would match "01". Try matching 2 or
more digits with \d{2,}.

Re: Help debugging code - Negative lookahead problem
Hi MRAB,
Thanks for taking time to look at my problem!
I tried your solution:
r"\d{2}\s?(?=(?:years old\s?|yo\s?|yr old\s?|y o\s?|yrs old\s?|year
old\s?)(?!son|daughter|kid|child))"
but unfortunately it does seem not work. Also, I tried adding the negative
lookaheads after every one of the alternatives, but it does not work either, so
the problem does not seem to be that the negative lookahead applies only to
the last proposition... : (
Also, \d{2} will only match two single digits, and won't match the last two
digits of 101, so at least this is fine! : )
Any other idea to improve that code? I'm starting to get desperate...
Thanks again for your help anyways, I really appreciate it! ; )

"python" is the recommended way to run Python that's cross-platform. The last thing I'd want is to see tutorials and FAQs filled with caveats that Windows users should use py -X[.Y[-32]] instead of python. It can be assumed that the environment is configured correctly for the python command to run the desired version of the interpreter. The best way to do that is to develop using virtual environments. Steve Dower (Microsoft) and Nick Coghlan (Red Hat) have made suggestions for a new "python" launcher that can run multiple versions and would be available on all platforms. I've yet to see any specific discussion about this idea on python-ideas or python-dev -- at least not to the point that someone is willing to write a PEP and start coding. It's just a pipe dream for now. > SystemRoot is not in my PATH variable. Open the environment variables editor in the system properties window; double-click on "Path" in the system variables and insert the following at the beginning: %SystemRoot%\System32;%SystemRoot%;%SystemRoot%\System32\Wbem; These are present by default when Windows is installed -- except %SystemRoot% may already be expanded to C:\Windows, or wherever Windows is installed on the system.

If your code becomes too complex to manage it break it into simpler parts.
In this case you can use two simple regular expressions:
>>> age = re.compile(r"\d+")
>>> child = re.compile(r"\s+kid")
>>> text = "42 bar baz foo 12 kid"
>>> for candidate in age.finditer(text):
... if child.match(text, candidate.end()):
... print("Kid's age:", candidate.group())
... else:
... print("Author's age:", candidate.group())
...
Author's age: 42
Kid's age: 12
Applying that idea (and the principle to break everything into dead easy
parts) to your problem:
$ cat demo.py
import re
def longest_first(text):
return sorted(text.splitlines(), key=len, reverse=True)
YEARS = longest_first("""\
year
years
year old
years old
yo
ys o
""")
CHILDREN = longest_first("""\
son
daughter
kid
child
""")
YEARS_RE = r"\b(?P\d+) ({})".format("|".join(YEARS))
re_years = re.compile(YEARS_RE)
CHILD_RE = r" ({})\b".format("|".join(CHILDREN))
re_child = re.compile(CHILD_RE)
def followed_by_child(candidate):
return re_child.match(candidate.string, candidate.end())
CORPUS = """\
jester, 42 years old, 20 years kidding
12 years kid
engineer, 30 years
engineer, 30 years old daughter
""".splitlines()
for text in CORPUS:
print(text)
for m in re_years.finditer(text):
age = m.group("age")
if followed_by_child(m):
print("rejected:", age)
else:
print("accepted:", age)
$ python3 demo.py
jester, 42 years old, 20 years kidding
accepted: 42
accepted: 20
12 years kid
rejected: 12
engineer, 30 years
accepted: 30
engineer, 30 years old daughter
rejected: 30

Ah, OK. I see what the problem is. (I should've marked it as "untested".
:-()
It matches r"yo\s?" against "yo " (the r"\s?" consumes the space) and
then the "son" alternative against "son", but that's a _negative_
lookahead, so it _fails_, so it backtracks.
It retries the r"\s?", which now matches an empty string (doesn't
consume the space), and then the "son" alternative against " son", which
fails, but that's a _negative_ lookahead, so it _succeeds_.
And the regex as a whole matches.
Ideally I'd want to use a possessive quantifier or atomic group, but
they aren't supported by the re module, so the workaround is to move the
check for whitespace:
r"\d{2}\s?(?=(?:years old|yo|yr old|y o|yrs old|year
old)(?!\s?son|\s?daughter|\s?kid|\s?child))"

Exposing all methods of a class
I use Python, mainly with Django, for work. I was wondering if anyone has encountered an editor that could display a class with all inherited methods included in the editor's view of the class code. I am kind of envisaging the inherited code would be displayed differently (say, grey vs black), and labelled with the name of the parent class so that it would provide a one-stop view of the entire class structure. I edit using vim, and use ctags to explore up the inheritance chain which is useful enough, but I feel it should be quite possible for the editor to search through the imports and grab the parent classes to insert into the editor view. Any suggestions? Maybe there are better ways of navigating inheritance but it does seem logical to expose the whole class code in one place, suitably annotated. I feel a plugin coming on.

That is the best. I have discovered another anomaly: asyncio names this "run_in_executor" but tornado names it "run_on_executor" ( http://www.tornadoweb.org/en/stable/concurrent.html#tornado.concurrent.run_on_executor ) I hope eventually they will become fully compatible. :-) Thanks for your help!
