Detect HTML Attributes

    My solution in python3: 

    # Enter your code here. Read input from STDIN. Print output to STDOUT
import re

txt1 = ""
N = int(input())
for i in range(N):
    txt_substring = input()
    txt1 += f" {txt_substring}"

tag_att_dict = {}

matches = re.findall(
    r'(?<=<)[^>]+(?=>)',
    txt1
)
for i in matches:
    # print(i)
    # Split
    split_list = i.split(' ')
    # Tag
    tag = split_list[0]
    if tag not in tag_att_dict and not tag.startswith('/'):
        tag_att_dict[tag] = []
    # print(tag)
    # Attributes
    matches2 = re.findall(
        r'[a-z]+(?=(?:\=\"|\=\'))',
        i
    )
    for j in matches2:
        if j not in tag_att_dict[tag]:
            tag_att_dict[tag].append(j)

tags = sorted(list(tag_att_dict.keys()))

for i in tags:
    sorted_atts = ','.join(sorted(tag_att_dict[i]))
    print(f"{i}:{sorted_atts}")
