Python: difficulty converting ascii to unicode -

-

my goal: page source url , count instances of keyword within page source

how doing it: getting pagesource via urllib2, looping through each char of page source , comparing keyword

my problem: keyword encoded in utf-8 while page source in ascii... running errors whenever try conversions.

getting page source:

import urllib2 response = urllib2.urlopen(myurl) return response.read()

comparing page source , keyword:

pagesource[i] == keyword[j]

i need convert 1 of these strings other's encoding. intuitively felt ascii (the page source) utf-8 (the key word) best , easiest, so:

    pagesource = unicode(pagesource) unicodedecodeerror: 'ascii' codec can't decode byte __ in position __: ordinal not in range(128)

i'll assume remote "source page" contains more ascii otherwise comparison work (ascii subset of utf-8. i.e. in ascii 0x41, same utf-8).

you may find python requests library easier automatically decode remote content unicode strings based on server's headers (unicode strings encoding neutral can compared without worrying encoding).

resp = requests.get("http://www.example.com/utf8page.html") resp.text >> u'my unicode data €'

you need decode reference data:

keyword[j] = "€".decode("utf-8") keyword[j] >> u'€'

if you're embedding non-ascii in source code, need define encoding you're using. example, @ top of source code/script:

# coding=utf-8

i have following code almost works properly; private void cbstatus_drawitem(object sender, listboxdrawitemeventargs e) { string item = e.item string; if (item != null) { switch (item) { case "1": e.appearance.forecolor = color.green; e.appearance.backcolor = color.green; break; case "2": e.appearance.forecolor = color.orange; e.appearance.backcolor = color.orange; break; case "3": e.appearance.forecolor = color.red; e.appearance.backcolor = color.red; break; } } } when dropdown shown, items forecolor correct, backcolor remains whatever backcolor of theme is; i.e. if i've got set dark theme, backcolor dark, cells in gridview, rather being green/orange/red. i've tried setting e.appearance.options.usebackcolor trying set e....
