Python HTMLParser and Vkontakte randomizer
Finally I've finish my first "program" on Python. The task is to parse people's id from web page where reposter's id stores. Main problems were:
- web-page code is loading dynamically so there is no simple way to get ids from it, the best solution was - save section where id stores in .html file
- I wanted to catch id + nickname but list of pairs was not a good decision when random works
- I can't create a list which stores all found ids, it wiped every iteration
- I have some unsupported chars in nicknames and they'd broke iteration
- I've get a lot of junk while scan .html so I used regex to avoid them
- I can't add various ids in list without adding one id to list recursively - and guess what? Yes, it's broke the iteration
What I've learned: Here will be a huge list of different things for indexing for further …
Read...Python HTMLParser
How to spent two days if you know nothing about Python:
- need parse HTML page code, where VK id and username of every person who shared post stores
with open('test.html', 'r', encoding='utf-8') as content_file: read_data = content_file.read() from html.parser import HTMLParser import re class MyHTMLParser(HTMLParser): def handle_starttag(self, tag, attrs): vk_id = str(attrs) for line in vk_id: vk = re.findall('/\S+$', vk_id) vk_fnd = str(vk) if re.search('/\w+\'\)\]', vk_fnd): global vk_read vk_read = vk_fnd for ch in ['/', ')', '[', ']', '"', "'"]: if ch in vk_read: vk_read = vk_read.replace(ch, "") def handle_data(self, data): global vk_name vk_name = str(data) assert isinstance(data, object) for line in vk_name: if re.match('\S+\s+\S+$', vk_name): print("@{0} - {1}".format(vk_read, vk_name)) break parser = MyHTMLParser() parser.feed(read_data)
Now I know more. First bug and first fix: UnicodeEncodeError: 'charmap' codec can't encode character '\u0406' in position 15: character maps to <undefined>
with open('test.html', 'r', encoding='utf-8') as content_file: read_data = content_file.read() ''' 1. …Read...
Plone installation
Will try to use Plone CMS for test cases, interesting to see what and how CMS on Python worked. Start here: https://plone.org/documentation/manual/installing-plone/installation-quick-guide For Python: Guide and I've use only one part from it here. I've done everything as guided above.

Заводим питончика дома или установка Python на Centos 6

How to install Python 2.7.6 on CentOS 6.3 (6.2 and 6.4 okay too, probably others)
stolen from Daniel Eriksson. Thanks Daniel! http://toomuchdata.com/2012/06/25/how-to-install-python-2-7-3-on-centos-6-2/ (modified a little) CentOS 6.2 ships with Python 2.6.6 and depends on that specific version. Be careful not to replace it or bad things will happen. If you need access to a newer version of Python you must compile it yourself and install it side-by-side with the system version. Here are the steps necessary to install Python 2.7.6. Execute all the commands below as root. Either log in as root temporarily or use sudo.
Install development tools
In order to compile Python you must first install the development tools:
yum groupinstall "Development tools"
You also need a few extra libs installed before compiling Python or else you will run into problems later when trying to install various packages:
yum install zlib-devel
yum install bzip2-devel …

Python array
Начинаю учить Пайтон, буду набивать шпаргалки.
lst = ['spam', 'drums', 100, 1234] print(lst[2]) 100
Это мой первый массив, детка. Спустя время, это может показаться для меня смешным, но сейчас я очень доволен собой.
