如何编写Python函数count_words统计3段文本的单词数量

待统计文本定义 #

text1 = "He is tall, fat and ugly."
text2 = "He is a very fearful and crying boy, but intelligent."
text3 = "She has a pretty face, but she's not very smart."

补全单词计数函数 #

通过拆分文本、清洗末尾标点的逻辑实现计数，补全后的代码如下：

def count_words(text):
    num_words = 0
    # 按空格拆分文本得到单词片段
    word_segments = text.split()
    for seg in word_segments:
        # 去除片段末尾的逗号、句号等非单词字符
        clean_word = seg.rstrip('.,!?')
        if clean_word:
            num_words += 1
    return num_words

调用函数输出结果 #

直接使用给定的调用逻辑即可：

num_words = count_words(text1)
print("Text 1")
print("The word number is %d" % num_words)

num_words = count_words(text2)
print("Text 2")
print("The word number is %d" % num_words)

num_words = count_words(text3)
print("Text 3")
print("The word number is %d" % num_words)

最终统计结果 #

• Text 1 单词数：6
• Text 2 单词数：10
• Text 3 单词数：10
