任务一：Python实现WordCount

1.创建wordcount.py

import re
from collections import defaultdict
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.
"""

def wordcount(text):
    words = re.findall(r'\b\w+\b', text.lower())
    counts = defaultdict(int)
    for word in words:
        counts[word]+=1
    return dict(counts)

counts = wordcount(text)
print(counts)

2.在开发机上运行

结果如下图所示：
