    Function of this script is to fast comment/uncomment single line without selection for Notepad++. 

    import re
line = editor.getCurLine()
p1 = re.compile('^(.*?)((?P<lt><!--+\s*)|(?P<rt>\s*--+>))(?P<block>.*?)((?(rt)|(?(lt)((?=<!--+\s*)|\s*--+>)))|$)')
p2 = re.compile('\r?(\s*)(.*)\s*\n')
if '<!--' in line or '-->' in line:
    line = p1.sub(r'\1\g<block>', line).rstrip()
else:
    line = p2.sub(r'\1<!-- \2', line).rstrip() + ' -->'

    + allows conditional instances of '<!-' and '->' in NON-GREEDY way
    + shortens '<!------' and '------->' cases
    + correctly handles reversed setting of comments "-> . . . <!-" and recognizes "<!- .  . <!- .  . ->" situations

    lol, forgot about printing: 

    currentLine  = editor.lineFromPosition(editor.getCurrentPos())
editor.replaceLine(currentLine, line)

    ok, i've made "some correction". hope its final nao 

    #Toggle HTML Comment >> PythonScript for Notepad++
# -comments single line without selection/removes comment tags in NON-GREEDY or GREEDY style (see options)
# -comments selection/clears all comments from selection
# -intelligently handles '--> ... <!--' or '<!-- . . <!-- .. -->' in relation to single line when nothing selected
# -recognizes incorrect tags like <!----
# -script can remove also stream comments '/* */' and others own defined, which macro in N++ was not supported
# -all of this under one shortcut. author: s1w_
#note: this is NOT begin-end validity checker, use HTML parsers instead
import re, string
class commentPair:
    """Objects of this class will contain pairs of comment tags;
    you can define your additional bracket pairs below.
    Constructor takes two parameters: <opening> and <closing>
    raw string describing new definition of comment pair.
    If you want use '\' char in parameter, you have to double it,
    because it is recognized as escape sign. '\\**' and '***\\\\'
    in fact is passed as '\**' and '***\\'. If you forget about
    this, you will have syntax error (quantity of '\' should be
    no different than even). Do not escape other characters!
    Order of defining comment pairs is crucial in this script,
    because it will determine comments recognition order.
    First (top) defined pair is used for main script functionality.
    Additional definitions apply only for operation of cleaning.
    It performs if script detects in selected text or in current
    line one of defined comments: step by step and in the same
    order as were defined (from top to bottom).
    To promote additional comment pair to main functionality, you
    will want to create multiple copies of this script under
    different names and binds each one under different shortcut
    key. Each instance of script may define different order of
    comment pairs."""
