should help you out I am fairly new to python. I have a this string , You'll need to get rid of repeats. A nice way is with a set.
code :
import re

mystring = """
DEALER: 'S up, Bubbless?
BUBBLES: Hey.
DEALER: Well, there you go.
JUNKIE: Well, what you got?
DEALER: I got some starters. """

p = re.compile('([A-Z]*):')
s = set(p.findall(mystring))

print s
set(['JUNKIE', 'DEALER', 'BUBBLES'])

I wish this helpful for you I want to split this String to give my desired output , This will work..
code :
public static void main(String[] args) {
String text = "sinXcos(b+c)tan(z)";
String patternString1 = "(sin|cos|tan)(?![a-z])\\(?\\w(\\+\\w)?\\)?";
Pattern pattern = Pattern.compile(patternString1);
Matcher matcher = pattern.matcher(text);
while (matcher.find()) {
    System.out.println(matcher.group());
}
}



O/P:
sinX
cos(b+c)
tan(z)

2. Input :"sinabc(X+y)cos(b+c)tan(z)";
O/P :
cos(b+c)
tan(z)
tring patternString1 = "(sin|cos|tan)(?![a-z])\\(?\\w(\\+\\w)?\\)?";
1. (sin|cos|tan) -->start with (sin or  cos or tan)
2. (?:![a-z]) --> negative lookahead. check if the next character is not in between [a to z].
3. \\(?\\w(\\+\\w)?\\)?--> an optional brace followed by an alphabet followed by a "+" and another alphabet.

wish of those help I have a string with some text and some URLs in it. My goal is to remove the following from the string: , try below:
code :
  $preg = '/(?:(http|https):\/\/)?(?:www\.)?\w+\.(com|net)/i';

$str = preg_replace_callback($preg, function($matches) {
    $removeThis = array('/http:\/\//i', 'https://', 'www.', '.com', '.net');
    if (preg_match('/(http|https):\/\/(www\.)?good\.(com|net)/i', $matches[0])) return $matches[0];
    return preg_replace('/((http|https):\/\/|www\.|\.com|\.net)/i', '', $matches[0]);
}, $string);

it should still fix some issue I have requirement to check if email in specific format and consists of specific words then number then specific words For example , It's really easy to make a regular expression to get matches:
code :
        string[] input = new string[6]
        {
            "Auto_gen_1234@mail.com", // match
            "Auto_gen_7302@mail.com", // match
            "Auto_gen_8928@mail.com", // match
            "Auto_gen_12345@mail.com", // not a match
            "Auto_gen_72@mail.com", // not a match
            "Auto_gen_Bob@mail.com" // not a match
        };

        string pattern = @"Auto_gen_\d{4}@mail.com";  //\d{4} means 4 digits
        foreach (string s in input)
        {
            if (Regex.IsMatch(s, pattern))
            {
                Console.WriteLine(string.Format("Input {0} is valid",s));
            }
            else {
                Console.WriteLine (string.Format("Input {0} is  not valid",s));
            }
        }
        Console.ReadKey();

Hope that helps Another option is capture groups, where we capture the characters or words of interest
code :
sub("^[0-9+-]+\\s*([^.]+).*", "\\1", vec)
#[1] "red and blue" "+AAA"         "-WW"          "AAA"

it helps some times This is a neat question. You can do this with some table and list M functions as a custom column like this:
code :
= Text.Combine(
      List.ReplaceMatchingItems(
          Text.Split([OriginalString], " "),
          List.Transform(Table.ToList([Replacements]),
              each Text.Split(_,",")
          )
      ),
  " ")
"aa &bb &cc dd" --Text.Split--> {"aa", "&bb", "&cc", "dd"}
StringToFind  ReplaceWith
------------------------------
&bb           ReplacementForbb
&bb           ccReplacement
{"&bb,ReplacementForbb","&cc,ccReplacement"}
{{"&bb","ReplacementForbb"},{"&cc","ccReplacement"}}
List.ReplaceMatchingItems(
    {"aa", "&bb", "&cc", "dd"},
    {{"&bb","ReplacementForbb"},{"&cc","ccReplacement"}}
)
{"aa","ReplacementForbb","ccReplacement","dd"}
"aa ReplacementForbb ccReplacement dd"
