    import re
p1 = r'{[^{}]*}'
p2 = r'#[\da-fA-F]{3,6}'
t = ''.join(input() for _ in range(int(input())))
t = ''.join(re.findall(p1, t))
print('\n'.join(re.findall(p2, t)))

    None of the regex patterns I see here will exclude #BED and #Cab. Am I missing something?

    This is how I did it

    pattern = r'(?<!^)#[0-9A-Fa-f]{3,6}'
