书生大模型实战营-入门第2关-python单词计数

统计单词数量

统计单词数量，拆分为以下几步：

1. 需要剔除文本中的标点符号与换行符
2. 大小写转换
3. 单词拆分计数

详细代码如下：

import re

def wordcount(text):
    """
    单词计数
    标点去除
    大小写转换
    """
    count = {}
    # 替换标点
    text = text.replace(",","").replace(".","").replace("\n","")
    # 转换大小写,分割
    text = text.lower().split(" ")
    for word in text:
        if word in count.keys():
            count[word] += 1
        else:
            count[word] = 1
    return count

text = """
Got this panda plush toy for my daughter's birthday,
who loves it and takes it everywhere. It's soft and
super cute, and its face has a friendly look. It's
a bit small for what I paid though. I think there
might be other options that are bigger for the
same price. It arrived a day earlier than expected,
so I got to play with it myself before I gave it
to her.
"""

wc = wordcount(text)

使用debug模式查看代码逻辑，配置debug的参数：

以debug模式运行，运行正常。
