在github上面有一个写的更好的
https://github.com/y1cunhui/cs61A-2021Fall/blob/main/proj02-cats/cats.py
写这个pro的时候可以多注意题目给的函数，大部分都用的上
problem1：
这个小题意思就是从paragraphs中挑选符合select函数的字符，然后输出第k个。
部分测试：
代码：
def choose(paragraphs, select, k):
"""Return the Kth paragraph from PARAGRAPHS for which SELECT called on the
paragraph returns True. If there are fewer than K such paragraphs, return
the empty string.
Arguments:
paragraphs: a list of strings
select: a function that returns True for paragraphs that can be selected
k: an integer
>>> ps = ['hi', 'how are you', 'fine']
>>> s = lambda p: len(p) <= 4
>>> choose(ps, s, 0)
'hi'
>>> choose(ps, s, 1)

num = 0
for i in paragraphs:
if select(i):
if num == k:
return i
else :
num += 1
return ''
# END PROBLEM 1
problem2：
这个小题意思是从传进来一句（paragraph），然后本身这个函数有一个list（a list of words related to a subject），如果这个paragraph中含有list中的单词就返回True,否则返回False
部分测试
代码：
def about(topic):
"""Return a select function that returns whether
a paragraph contains one of the words in TOPIC.

topic: a list of words related to a subject
>>> about_dogs = about(['dog', 'dogs', 'pup', 'puppy'])

'Its a lovely day dont you think'
"""
punctuation_remover = str.maketrans('', '', string.punctuation)
return s.strip().translate(punctuation_remover)
problem3：
这个题目意思就是给定两个字符列表一个type，一个reference，都为空就返回100，其中某一个为零就是返回0，
然后按照一一对应的方式，看type和reference中相等的个数有多少，然后用这个数字取比type的个数，输出百分比。（标点也算，转义符不算）

problem4:
这个题目意思就是输一个字符串，计算他的字符个数（算空格）然后以每五个字符算一个单词，第二个参数是耗时（秒），计算每分钟可以打多少单词
部分测试：
代码：
def wpm(typed, elapsed):
"""Return the words-per-minute (WPM) of the TYPED string.

problem5:
这个题目意思就是给定一个输入字符t和一个判断字符列表v，如果t在v里面就返回t如果不在，就用一个判断函数判断t与v里面每一个字符，差距返回一个数字，如果数字小于给定的limit就返回那个和
t判断字符，如果多个字符判断数字相等就返回第一个出现在列表里面的，如果都大于limit则返回t本身。

problem6:
这个题目的意思就是比较两个字符的差距，不同就修改，长短不一就加一个，这两个步骤都算一步，最后计算需要的步数，如果需要的步数大于limit，则需要立马结束递归。
部分测试：
代码：
