Python中使用多个函数的字计数器

我目前正在做一个我被分配的程序，这个程序只是得到一首十四行诗的字数和行数。这里的第一段代码是有效的，是我的教授想要的正确的输出，尽管它包含了十四行诗的前两行

import string


def main():

    ifName = input("What file would you like to analyze? ")
    ofName = input("What file should the results be written to? ")

    infile = open(ifName, "r")
    outfile = open(ofName, "w")

    lineCount = 0
    wordCount = 0

    for line in infile:
        lineCount +=1
        wordLine = line.split()
        L = len(wordLine)
        wordCount += L


    print("The file", ifName, "had:", file= outfile)
    print("words =", wordCount, file= outfile)
    print("lines =", lineCount, file= outfile)
    print("The results have been printed to:", outfile)

    infile.close
    outfile.close

main()

但是，赋值的下一部分是使用参数为“line”的第二个函数“countNum”获得相同的结果。所以countNum（行）

这是我一直在乱搞的代码，看看我是否能让它工作

import string


def countNum(line):
    wordCount = 0
    wordLine = line.split()
    L = len(wordLine)
    wordCount +=L
    print(wordCount)

def main():

    ifName = input("What file would you like to analyze? ")
    ofName = input("What file should the results be written to? ")

    infile = open(ifName, "r")
    outfile = open(ofName, "w")

    lineCount = 0
    wordCount = 0

    for line in infile:
        lineCount +=1
        wordTotal += countNum(line)
        ##wordLine = line.split()
        ##L = len(wordLine)
        ##wordCount += L


  ##  print("The file", ifName, "had:", file= outfile)
  ##  print("words =", wordCount, file= outfile)
  ##  print("lines =", lineCount, file= outfile)
  ##  print("The results have been printed to:", outfile)

    infile.close
    outfile.close

main()

如果您想知道，这是sonnet.txt文件：

Shakespeare’s Sonnet 18 Shall I compare thee to a summer's day? Thou art more lovely and more temperate: Rough winds do shake the darling buds of May, And summer's lease hath all too short a date: Sometime too hot the eye of heaven shines, And often is his gold complexion dimm'd; And every fair from fair sometime declines, By chance or nature's changing course untrimm'd; But thy eternal summer shall not fade Nor lose possession of that fair thou owest; Nor shall Death brag thou wander'st in his shade, When in eternal lines to time thou growest: So long as men can breathe or eyes can see, So long lives this, and this gives life to thee. 莎士比亚十四行诗18 我能把你比作夏日吗？ 你更可爱，更温和： 狂风吹拂着五月可爱的花蕾， 夏天的租约日期太短了： 有时候，天眼的光芒过于炽热， 他金色的肤色常常黯淡； 每一个集市都会有衰落的时候， 由于偶然或自然的变化过程而未受影响； 而你如仲夏繁茂不凋谢 也不要失去你所拥有的美丽； 死亡也不会吹嘘你在他的阴影下徘徊， 当你在永恒的诗句中成长时： 只要人能呼吸，眼睛能看见， 这生命如此长久，这给了你生命。

您的

countNum

正在打印结果，而不是返回结果：

def countNum(line):
    return len(line.split())

此外，您的close方法后面需要有

（）

。他们实际上并没有执行：

infile.close
outfile.close

infile.close()
outfile.close()

您可以使用

len

获取列表的长度。行列表由

f.readlines（）

给出，行中的单词列表由

line.split（）

给出。我们可以使用内置的

sum

来对一个列表进行求和，并且是超级pythonic

您应该通过使用

with

关键字来使用Python的自动关闭

所以我们有：

with open(infilename, "r") as infile, open(outfilename, "w") as outfile:
    lines = infile.readlines()
    linecount = len(lines)
    wordcount = sum([len(line.split()) for line in lines])
    print(linecount)
    print(wordcount)

有关列表理解的信息，请参见

是否要计算一行中每个单词的出现次数？只需从函数返回wordCount即可return wordCount'顺便说一句，你并没有真正关闭你的文件。

with open(infilename, "r") as infile, open(outfilename, "w") as outfile:
    lines = infile.readlines()
    linecount = len(lines)
    wordcount = sum([len(line.split()) for line in lines])
    print(linecount)
    print(wordcount)
