Regex to match character in specific position and specific length

原文 2018-09-26 10:28:25 5 1 python/ regex

I need to find string with length of 12 and contains in the 7 position the char "U".

I have the following strings:

SUPERHUMANLY
DFGDFGDFGGFG
SUPSRHTMANLY
DFGDFGUFGGFG

Only the following should matched:

SUPERHUMANLY
DFGDFGUFGGFG

Following this link I know how to get match on the 7 position:

^.{6}[U]

But I want to get match on only letters with specific length, so I tried ^.{6}[U]{12} , ^(.{6}[U]){12} and ^.{6}[U].{12} without success.

How can I combine the length of the string with the position ?
