Algorithm
Problem Name: Python -
In this HackerRank Functions in PYTHON problem solution,
*This section assumes that you understand the basics discussed in HTML Parser - Part 1
.handle_comment(data)
This method is called when a comment is encountered (e.g. <!--comment-->).
The data argument is the content inside the comment tag:
from HTMLParser import HTMLParser
class MyHTMLParser(HTMLParser):
def handle_comment(self, data):
print "Comment :", data
.handle_data(data)
This method is called to process arbitrary data (e.g. text nodes and the content of <script>...</script> and <style>...</style>).
The data argument is the text content of HTML.
from HTMLParser import HTMLParser
class MyHTMLParser(HTMLParser):
def handle_data(self, data):
print "Data :", data
Task
You are given an HTML code snippet of
lines.
Your task is to print the single-line comments, multi-line comments and the data.
Print the result in the following format:
>>> Single-line Comment
Comment
>>> Data
My Data
>>> Multi-line Comment
Comment_multiline[0]
Comment_multiline[1]
>>> Data
My Data
>>> Single-line Comment:
Note: Do not print data if data == '\n'.
Input Format
The first line contains integer N. the number of lines in the HTML code snippet.
The next N lines contains HTML code.
Constraints
0 < N < 100
Output Format
Print the single-line comments, multi-line comments and the data in order of their occurrence from top to bottom in the snippet.
Format the answers as explained in the problem statement.
Sample Input
4
<!--[if IE 9]>IE9-specific content
<![endif]-->
<div> Welcome to HackerRank</div>
<!--[if IE 9]>IE9-specific content<![endif]-->
Sample Output
>>> Multi-line Comment
[if IE 9]>IE9-specific content
<![endif]
>>> Data
Welcome to HackerRank
>>> Single-line Comment
[if IE 9]>IE9-specific content<![endif]

Python Programming
from html.parser import HTMLParser
class MyHTMLParser(HTMLParser):
def handle_comment(self, data):

print(">>> Data", data, sep="\n")
html = ""
for i in range(int(input())):
html += input().rstrip()
html += '\n'
parser = MyHTMLParser()
parser.feed(html)
parser.close()
