Question

['boxoffice.csv', 'games.csv', 'imdb.csv', 'olympics-locations.csv', 'olympics-results.csv', 'oscar-actor.csv', 'oscar-film.csv', 'seinfeld-episodes.csv', 'seinfeld-foods.csv']
我要把.csv之前的东西，即boxoffice， games等提取出来， 变成一个list
感激不尽！

Answer 1

new_l中就会是你想要的.

l = ['boxoffice.csv', 'games.csv', 'imdb.csv', 'olympics-locations.csv', 'olympics-results.csv', 'oscar-actor.csv', 'oscar-film.csv', 'seinfeld-episodes.csv', 'seinfeld-foods.csv']
new_l = [e[:-4] for e in l]
