Sorting x lists based on one list ... maybe an example would make sense:

[Philippe C. Martin]

l1 = ['a','b','c']
l2 = ['toto','titi','tata'] # 'toto' refers to 'a', 'titi' to b' ....
l3 = ['foo','bar','doe'] # 'foo' refers to 'a' ........

I want to reverse sort l1 and have l2 and l3 follow accordingly.

Regards,

Philippe
