Python 计算非冠词

尝试获取defcountnonarticlewords以计算mobydick文本文件中非文章词的数量。我试图不计算的单词有“a”、“an”和“The”。关于如何修改def countNonParticleWords以输出示例1的任何提示。目前正在输出示例2

示例#1

示例2

到目前为止，我所拥有的：

def getTextFile():
        filename=input("Enter the test file name: ")
        textFile=open(filename, 'r')
        return filename,textFile

def outputcountresults(filename, linecount, charcount, wordcount, nonarticlewordcount):
    print("*****{}*****".format(filename))
    print("Total Lines: {}".format(linecount))
    print("Total Chars: {}".format(charcount))
    print("Total Words: {}".format(wordcount))
    print("Total Non-Article Words: {}".format(nonarticlewordcount))

def countcharacters(line):
    charcount=0
    for c in line:
        if not c.isspace():
            charcount= charcount +1
    return charcount

def countnonarticlewords(line):
    nonarticlewords= line.split()
    nonarticlewords=0
    for nonarticle in line:
        #nonarticlewords= line.split()
        if not 'a' or 'an' or 'the':
            nonarticlewords= nonarticlewords +1
    return len(nonarticle)

def countwords(line):
    words= line.split()
    return len(words)

def countdocstats(docFile):
    linecount=0
    totalcharacters=0
    totalwords=0
    totalnonarticlewords=0
    for line in docFile:
        linecount= linecount + 1
        totalwords= totalwords + countwords(line)
        totalcharacters=totalcharacters+countcharacters(line)
        totalnonarticlewords= totalnonarticlewords + countnonarticlewords(line)
    return linecount, totalcharacters, totalwords, totalnonarticlewords

def main():
    filename, textFile=getTextFile()
    linecount, totalcharacters, totalwords, totalnonarticlewords= countdocstats(textFile)

    outputcountresults(filename,linecount,totalcharacters,totalwords,totalnonarticlewords)
main()

不知何故，每次人们都会犯同样的错误。不，说真的，你认为

如果不是'a'或'an'或'the'

怎么办？

如果在{'a'，'an'，'the'}中没有任何一个条目，你会犯几个错误。对于初学者，您可以执行
nonarticlewords=line.split（）
，然后紧接着执行
nonarticlewords=0
，从而使前一行变得毫无意义。然后直接在第行上迭代，对第行中的非项目使用
，
，但对第行中的非项目使用
进行迭代。split（）
。最后，检查：
如果不是“a”或“an”或“the”
没有做你认为它正在做的事情
