fixed the issue. Will look into that further You are mistaking a character class with the grouping operator. Consider:
code :
(?:<|>|<=|>=)?\d+
(<|>|<=|>=)?(\d+)

This might help you In a regular expression you can quantify the number of times something appears with {min,max} following the token. ie.
code :
\({2,}(.*?)\){2,}

this one helps. I'm using TextWrangler grep to perform find/replace on multiple files and have run into a wall with the last find/replace I need to perform. I need to match any text between "> and the first instance of a
in a line but the match cannot contain the character sequence [xcol]. The regex flavor is Perl-Compatible (PCRE) so lookbehind needs to be fixed-length. , Try this regex:
code :
">((?!\[xcol]).)*<br\s*/>
">               # match '">'
(                # start group 1
  (?!\[xcol]).   #   if '[xcol]' can't be seen ahead, match any character (except line breaks)
)                # end group 1
*                # repeat group 1 zero or more times
<br\s*/>         # match '<br />'
Is it possible for C/C++ PCRE to match 2 or more UTF-8 codepoints which are far apart from each other in a UTF-8 String?

With these it helps Using PCRE, the regex you would use to match those appearing anywhere in a string is the following: \x{00E4}.*\x{00F6}

I wish this help you what I found was that using " b[40] = '\0' " gives you a correct answer. But if you are using it in for loops, you have to keep track of when you hit a null '\0' to break. which would mean you reached the end. I didn't realize I had a working answer until a day afterwards.
Anyway, my TA ended up telling me that I was doing a lot more than I was asked, i.e I never needed to do this.

it helps some times You can just use different frequencies to supply to the wordcloud.
E.g.
code :
d[a] = 3-x
d[a] = 1./x
top_10 = lambda :""
top_10.values = [[u'nice', 2.0886619578149417],
                 [u'owl', 2.2729656758128876],
                 [u'person', 2.386294361119891],
                 [u'read', 2.455287232606842],
                 [u'seat', 2.5766480896111092]]
d = {}
for a, x in top_10.values:
    d[a] = 3-x

import matplotlib.pyplot as plt
from wordcloud import WordCloud

wordcloud = WordCloud()
wordcloud.generate_from_frequencies(frequencies=d)
plt.figure( figsize=(5,3) )
plt.imshow(wordcloud, interpolation="bilinear")
plt.axis("off")
plt.show()
