i'm attempting capture '\\' python regex via re module. have attempted using: back = re.compile(r"'\\'") print back.findall(line) where line is: char = '\\'; but doesn't capture anything. i tried: = re.compile("'\\\\'") print back.findall(line) to no avail. what's wrong regex? you need escape backslash: back = re.compile(r"'\\\\'") code: >>> = re.compile(r"'\\\\'") >>> line = r"char = '\\';" >>> print back.findall(line) ["'\\\\'"]

i have working svm , countvectorizer works fine when input transform function list of strings. however, if pass 1 string it, vectorizer iterates through each character in string , vectorizes each one, though set analyzer parameter word when constructing countvectorizer . for x in range(0,3): test=raw_input("type message classify: ") v=vectorizer.transform(test).toarray() print(v) print(len(v)) print(svm.predict(vectorizer.transform(test).toarray())) i'm able fix issue changing second line in above code to: test=[raw_input("type message classify: ")] but seems strange have 1-item list. isn't there better way without constructing list? it expects list or array of documents when pass in single string assumes each element of string document (ie: character). try changing svm.predict(vectorizer.transform(test).toarray()) svm.predict(vectorizer.transform([test]).toarray()) ps: toarray() part not

i came across strange situation using parallel stream lambda in static initializer takes seemingly forever no cpu utilization. here's code: class deadlock { static { intstream.range(0, 10000).parallel().map(i -> i).count(); system.out.println("done"); } public static void main(final string[] args) {} } this appears minimum reproducing test case behavior. if i: put block in main method instead of static initializer, remove parallelization, or remove lambda, the code instantly completes. can explain behavior? bug or intended? i using openjdk version 1.8.0_66-internal. i found bug report of similar case ( jdk-8143380 ) closed "not issue" stuart marks: this class initialization deadlock. test program's main thread executes class static initializer, sets initialization in-progress flag class; flag remains set until static initializer completes. static initializer executes parallel stream, causes lambd

i have txt file , want save in array urls starting http:// , ends .png or .jpg or .jpeg. how can that? can use this? <?php function geturls($string) { $regex = '/https?\:\/\/[^\" ]+/i'; preg_match_all($regex, $string, $matches); return ($matches[0]); } $urls = geturls($string); foreach($urls $url) { echo $url.'<br />'; } ?> is correct? the function showed not work because there's nothing specifying .png , .jpg , or .jpeg in regex. return first match: $matches[0] . additionally, needs /g flag find multiple instances in same string ( /i ignores case). try instead: <?php function geturls($string) { // \w word character $regex = '/https?\:\/\/[\w]+\.(jpg|png|jpeg)/ig'; preg_match_all($regex, $string, $matches); return ($matches); } $urls = geturls($string); foreach($urls $url) { echo $url.'<br />'; } ?>
