I need to match a pattern as follows with the added limitation that the match must be exactly 7 characters long: /^\d[a-zA-Z]\d$/ In words, this is a 7 character sequence of 6 digits and one alphabetic character in any order. How do I limit the overall length to 7 using regex? Thanks!

Esta expresión regular permite detectar las variables que están declaradas dentro de una url o route del framework Flask, con esto lo único que queda es armar un loop que recorra las coincidencias y que las remplace por los valores adecuados

Parsing html with regex is bad though.
