我是靠谱客的博主 迷人帽子,这篇文章主要介绍Coursera Chaptereight:Lists Assignment 8.4,现在分享给大家,希望可以做个参考。

8.4  Open the file  romeo.txt  and read it line by line. For each line, split the line into a list of words using the split()  method. The program should build a list of words. For each word on each line check to see if the word is already in the list and if not append it to the list. When the program completes, sort and print the resulting words in alphabetical order.

You can download the sample data athttp://www.pythonlearn.com/code/romeo.txt




fname = raw_input("Enter file name: ")


fh = open(fname)
lst = list()
for line in fh:
    line=line.rstrip()
    a=line.split()
    lst.append(a)
    l2=list()
for i in range(len(lst)):
    l2=l2+lst[i]
l2=list(set(l2))
l2.sort()
print l2
