Python regex (.*?) isn't giving an output

this one helps. You need to either include the newline characters \n in the regular expression, like this,
r'if __name__ == "__main__":\n(.*?)\n#END'

Why this regex not giving expected output?

This might help you As other people have told you in the comments, HTML is not a regular language so using regex for manipulating it is usually painful. Your best option is to use an HTML parser. I haven't used Jsoup before, but googling a little bit it seems you need something like:
import org.jsoup.*;
import org.jsoup.nodes.*;
import org.jsoup.select.*;

public class MyJsoupExample {
    public static void main(String args[]) {
        String inputText = "<html><head></head><body><p><img src=\"getCustomers.do?custCode=2&customerId=3334&param1=123\"/></p>"
            + "<p>someText <img src=\"getCustomers.do?custCode=2&customerId=3340&param2=456\"/></p></body></html>";
        Document doc = Jsoup.parse(inputText);
        Elements myImgs = doc.select("img[src*=customerId=3340");
        for (Element element : myImgs) {
            element.replaceWith(new TextNode("my replaced text", ""));
Elements myImgs = doc.select("img[src*=customerId=3340");
element.attr("src", "my new value"));
String srcValue = element.attr("src");
element.attr("src", srcValue.replace("getCustomers.do", "getCustonerNew.do"));

Regex not giving the expected output

hop of those help? You are not getting adjacent matches, because you are matching the ".\\s" of the next pattern in the previous pattern. So, they won't be matched again.
You should use look-arounds:

same dynamic regex and inline regex not giving same output in javascript

I hope this helps . In the first case, you have a string literal, which uses \ to introduce escape sequences. \d in a string is just d. If you want \d, you need to type \\d instead.
In the second case, you have a regular expression literal, which does not interpret \ as a string escape sequence.

Regex not giving output as desired

hop of those help? I am using the regex - [{]{[}][}] for the input {{id}} The output I expect is id. But I am getting {{id}}. , You use patter group incorrectly. Try this one:
String patternString = "[{][{](?<id>.*)[}][}]";
// String patternString = "\\{\\{(?<id>[^}]+)}}";
Pattern pattern = Pattern.compile(patternString);
Matcher matcher = pattern.matcher(string);
List<String> allMatches = new ArrayList<>();
while (matcher.find()) {
String patternString = "[{][{](.*)[}][}]";
//String patternString = "\\{\\{([^}]+)}}";
Pattern pattern = Pattern.compile(patternString);
Matcher matcher = pattern.matcher(string);
List<String> allMatches = new ArrayList<>();
while (matcher.find()) {

My Python regex code is not giving me the output as i expected

hope this fix your issue You code fails because in each iteration you read only one line (which can contain host or version but not both, yet you write data into csv. Let's iterate through all the text while matching twoliners: with first line Hostname.. and second line version... \n works as line break for Windows (I hear Mac uses \r not sure). Now since you match twoliners you can grab both router and version from same match object.
with open('testfile.txt','r',encoding='utf-8') as input:
       txt = input.read()
       pattern = re.compile(r'Hostname (.*)(\r\n?|\n)version (.*)')
       for match1 in match:
          with open('sample5.csv', 'a',newline='') as output:
             writer = csv.DictWriter(output, fieldnames=HeaderFields)
             writer.writerow({'Hostname': match1.group(1), 'version':
