本文實例講述了Python實現對文件進行單詞劃分并去重排序操作。分享給大家供大家參考，具體如下：

文件名：test1.txt

文件內容：

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

樣例輸出：

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的寫法：（二重循環）

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)

自己一重循環寫法：

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)
