我该如何修复我的程序？计算输入文件中的文章

Question

我需要计算输入文件中的冠词 (a, an, and, the)。下面是我写的代码。它计算文章，但它也计算单词中的字母或字母串，例如单词"sand"或单词"thanks"将被算作一篇文章。如何调整我的代码？

def countArticles (line):
    articleCount = 0
    for art in line:
        if art ==" a " or art ==" A " or art == " An " or art ==" an " or art ==" and " or art == "And "  or art ==" the " or art ==" The ":
            articleCount = articleCount + 1
    return articleCount

Answer 1

我可能会这样尝试：

def countArticles (line):
    articleCount = 0
    for art in line.lower().split(' '): # Make the words all lowercase, split on spaces.
        if art in ("a", "an", "and", "the"):
            articleCount = articleCount + 1
    return articleCount
