如何在Python中從文本文件中排序單詞

Question

我寫了一個Python腳本，用於打印文本文件中的所有單詞：

file = open(raw_input("Enter a file name: "))

for line in file:
    for words in line.split():
        print words

但是如何按順序打印出來呢？

Answer 1

如果要對每一行中的單詞進行排序，可以使用sorted ：

with open(raw_input("Enter a file name: ")) as f :

   for line in f:
      for words in sorted(line.split()):
        print words

但是，如果要按排序順序打印所有單詞，則需要對所有單詞應用排序：

with open(raw_input("Enter a file name: ")) as f :
     for t in sorted(i for line in f for i in line.split()):
           print t
