计算文本中的单词数（使用更正的代码并添加已提出的问题“计算文本中的单词数”）

  • 772

我修改后的解决方案是这样的：我们用文字将其分解 - 我们删除所有不必要的内容。在循环中，我们检查该单词是否被禁止并增加计数器 - 我们还添加了禁止单词，将其翻译为大写（）和一个空格并将其放入集合中

我收到这样的提示：方向是由Enikeyshchik指示的，但是单词可以以大写字母开头，例如“and”和“And”是不同的单词。

import codewars_test as test

import re

except_word = {"a", "the", "on", "at", "of", "upon", "in", "as",
               "A", "The", "On", "At", "Of", "Upon", "In", "As", ""
               }


def word_count(s):
    all_word = re.sub(r'([^A-Za-z]+)', r' ', s).split(' ')
    cnt = 0
    for word in all_word:
        if word in except_word:
            continue
        else:
            cnt += 1
    return cnt


if __name__ == '__main__':
    test.assert_equals(word_count("hello there"), 2)
    test.assert_equals(word_count("hello there and a hi"), 4)
    test.assert_equals(word_count("I'd like to say goodbye"), 6)
    test.assert_equals(word_count("Slow-moving user6463 has been here"), 6)
    test.assert_equals(word_count("%^&abc!@# wer45tre"), 3)
    test.assert_equals(word_count("abc123abc123abc"), 3)
    test.assert_equals(word_count("Really2374239847 long ^&#$&(*@# sequence"), 3)

    long_text = r"""
            I’d been using my sphere as a stool. I traced counterclockwise circles on it with my fingertips and it shrank until I could palm it. My bolt had shifted while I’d been sitting. I pulled it up and yanked the pleats straight as I careered around tables, chairs, globes, and slow-moving fraas. I passed under a stone arch into the Scriptorium. The place smelled richly of ink. Maybe it was because an ancient fraa and his two fids were copying out books there. But I wondered how long it would take to stop smelling that way if no one ever used it at all; a lot of ink had been spent there, and the wet smell of it must be deep into everything.
            """

    test.assert_equals(word_count(long_text), 112)

现在我的函数可以生成基本测试的正确答案

来自服务器的随机测试未通过，与所有其他随机测试一样，结果总是多 1 个单词

服务器的答案是 134 - 我有 135 - 对于所有随机测试都是如此

请解释一下，这是什么原因？就好像我忘记删除某些东西（我不明白是什么）。

    将所有内容转换为相同（例如小写）大小写，然后进行比较。
