Hi, a was wondering how i could find a case-sensitive string inside of another string. But the case-sensitive string is not known. ...

Find a 7 character string, but string is made up of A-Z A-Z A-Z a-z A-Z A-Z A-Z. So the string is made up 3 capital characters A-Z, 1 lowercase character, and then 3 capitol characters.

Example

runverUNCunruynXGTyERQvbrBNURBNIBuirRGRGRntuvrn

so in the above string, the python script would find XGTyERQ because the first 3 characters are uppercase and the 4th character is lower, and then the last 3 characters are uppercase.

Any ideas???

Hey,

I dont know if am getting your question correclty but to just get a string "XGTyERQ" from runverUNCunruynXGTyERQvbrBNURBNIBuirRGRGRntuvrn is actually pretty straight forward.
