Reading a local word list If you’re doing this repeatedly, I would download it locally and pull from the local file. *nix users can use /usr/share/dict/words. Example: word_file = “/usr/share/dict/words” WORDS = open(word_file).read().splitlines() Pulling from a remote dictionary If you want to pull from a remote dictionary, here are a couple of ways. The requests … Read more
Update: In Python 3.6, dict has a new implementation which preserves insertion order. From Python 3.7, this order-preserving behaviour is guaranteed: the insertion-order preservation nature of dict objects has been declared to be an official part of the Python language spec. This is the result of a security fix from 2012, which was enabled by … Read more
Yes, you could look at the table in the Pythons Developer Guide for most releases. Specifically Python 3.3 will have security fixes until 2017-09-29. Additionally, appropriate PEPs exist (google-able or from the devguide table) for each branch where a lifespan section specifies these. For 3.3 in PEP 398: 3.3 will receive bugfix updates approximately every … Read more
Simple example from collections import OrderedDict d = OrderedDict() d[‘a’] = 1 d[‘b’] = 2 d[‘c’] = 3 for key, value in d.items(): print key, value Output: a 1 b 2 c 3
The easiest way is with a regexp import re a=”lkdfhisoe78347834 (())&/&745 ” result = re.sub(‘[^0-9]’,”, a) print result >>> ‘78347834745’
Install the following module which adds the 2to3 command directly to entry_points. pip install 2to3 As it is written on 2to3 docs, to translate an entire project from one directory tree to another, use: 2to3 –output-dir=python3-version/mycode -W -n python2-version/mycode
The urllib module has been split into parts and renamed in Python 3 to urllib.request, urllib.parse, and urllib.error. Import urllib.request instead of urllib. import urllib.request
The way you use the csv module changed in Python 3 in several respects (docs), at least with respect to how you need to open the file. Anyway, something like import csv with open(‘test.csv’, ‘w’, newline=””) as fp: a = csv.writer(fp, delimiter=”,”) data = [[‘Me’, ‘You’], [‘293’, ‘219’], [’54’, ’13’]] a.writerows(data) should work.
This is a new feature in Python 3.3. Much like return in a generator has long been equivalent to raise StopIteration(), return <something> in a generator is now equivalent to raise StopIteration(<something>). For that reason, the exception you’re seeing should be printed as StopIteration: 3, and the value is accessible through the attribute value on … Read more
