[L3] regex help?

[Angela]

From the clue i believe i should be looking for a pattern = 3 uppercase letters followed by 1 lower case letter, followed by 3 upper case letters. I'm using regex to find this pattern: 

matcher= re.compile(r'([A-Z])\1{2}([a-z])([A-Z])\1{2}')

but it's not pulling anything. What am I doing wrong? 

TIA!!!

I'm not quite sure but try {3} instead of {2}. Also, keep in mind that the pattern is ONLY 3 uppercase letters followed by a lowercase letter followed by ONLY 3 uppercase letters.

print(re.findall(r"[A-Z]{3}[a-z]{1}[A-Z]{3}",strings))
