    For Python 3:

    import re
tag_pattern = re.compile(r'<\s*(?!/|!)([A-Za-z][\w\-]*)',re.ASCII)

number_of_lines = int(input())
unique_tag_names = set()
for _ in range(number_of_lines):
    html_line = input()
    unique_tag_names.update(tag_pattern.findall(html_line))
    
print(";".join(sorted(unique_tag_names)))

    import re T = int(input())

    pattern = r'\<([A-Za-z0-9]{1,})|\<\s+([A-Za-z0-9]{1,})' tag_set = set()

    while T>0: line = input() pattern_found = re.findall(pattern, line) for p in pattern_found: tag_set.add(p[0]) tag_set.add(p[1]) T-=1

    print(";".join(sorted([tag for tag in tag_set if len(tag) > 0 ])))

    Python:

    import re; html = "\n".join([input() for _ in range(int(input()))]); print(";".join(sorted(set(re.findall(r"<\s?([a-zA-Z]+[0-9A-Za-z])[^>]>", html)))));
