Pourquoi ce script python ne fonctionnera-t-il pas sur des jokers dans les noms de fichiers dans Win XP?

Question

Que devrais-je changer pour faire du travail sur Windows XP en gardant à l'esprit que nous travaillons sur Python 2-4?

Answer 1

Les langages de programmation ne supportent généralement pas la globalisation de shell sans que vous en ayez l'intention. Vous allez vouloir utiliser le Globbing module pour obtenir cette fonctionnalité.

Answer 2

Je pense que smth comme cela doit travailler pour vous

import glob#on the top of script 
#..... 
for filename in args: 
    for match in glob.iglob(filename):#we use 'glob' module for support wildcards 
     RenameFile(options, match)
