How to write zsh/python filename expansion with backreferences? -

-

i have files following structure

env1.current/bin/env1/filename env2.current/bin/env2/filename env3.current/bin/env3/filename env4.current/bin/env3/filename

how list above files? similar below? 

ls (.*).current/bin/\1/filename  #doesn't work!

is possible in list in python? glob module doesn't support backreferencing.
