re.findall not picking up some words

Question

After a post I'd seen on here, I tried to use the suggestion (finding double vowel words e.g (wood, sleep) into a code I've done so time back, but i wanted to return every double letter word e.g ...hello, setter, getter etc. My original code does do what I need, but using the new "pattern" some words are not being "found".
My string has some random double letter words...just for testing.

If you do reply and I don't get back to you ...sorry...it's late and I'm off to bed but I will respond tomorrow.
Thank you in advanced.

Answer 1

Your regex uses the string "string.ascii_letters" itself as the pattern, not the value of the variable (i.e. the lowercase/uppercase letters). It matches the characters "s", "t", "r", "i", "n", "g", ".", "a", "c", "_", "e".

You can solve this using string interpolation:

pattern = rf'([{string.ascii_letters}])\1'

Or using regex notation:

pattern = r'[a-zA-Z]'
