本文实例讲述了Python实现对文件进行单词划分并去重排序操作。分享给大家供大家参考,具体如下:

文件名:test1.txt

文件内容:

But soft what light through yonder window breaks It is the east and Juliet is the sun Arise fair sun and kill the envious moon Who is already sick and pale with grief

样例输出:

Enter file name: "test1.txt" ['Arise', 'But', 'It', 'Juliet', 'Who', 'already', 'and', 'breaks', 'east', 'envious', 'fair', 'grief', 'is', 'kill', 'light', 'moon', 'pale', 'sick', 'soft', 'sun', 'the', 'through', 'what', 'window', 'with', 'yonder']

PR4E 用 append的写法:(二重循环)


import sys
fname = input("Enter file name: ")
fh = open(fname)
lst = list()
for line in fh:
 line = line.rstrip()
 words = line.split()
 for word in words:
 if word not in lst:
 lst.append(word)
lst.sort()
print(lst)

自己一重循环写法:


import string
fname = input("Enter file name: ")
fh = open(fname)
l = list()
for line in fh:
 line = line.rstrip()
 l = l + list(line.split())
s = list(set(l))
s.sort()
print(s)
