我有txt文件,如下所示:

word, 23
Words, 2
test, 1

我希望它们看起来像这样:

word, 23

test, 4

我希望能够在Python中获取一个txt文件并将多个单词转换为单数.这是我的代码:

import nltk

f = raw_input("Please enter a filename: ")

def openfile(f):
    with open(f,'r') as a:
       a = a.read()
       a = a.lower()
       return a

def stem(a):
    p = nltk.PorterStemmer()
    [p.stem(word) for word in a]
    return a

def returnfile(f, a):
    with open(f,'w') as d:
        d = d.write(a)
    #d.close()

print openfile(f)
print stem(openfile(f))
print returnfile(f, stem(openfile(f)))

我也尝试过这两个定义而不是stem定义:

def singular(a):
    for line in …
