1、1. 已知字符串变量s= “The Zen of Python, by Tim PetersBeautiful is better than ugly.Explicit is better than implicit. Simple is better than complex.Complex is better than complicated. ” 试编程，实现如下功能: (1)对s中每个单词出现的次数进行统计，并将结果进行输出。 (2)输出出现次数排在前五名的单词。python

可以使用Python的字符串方法和列表、字典等数据结构完成这个任务。下面是一个实现该功能的示例代码：

s = "The Zen of Python, by Tim PetersBeautiful is better than ugly.Explicit is better than implicit. Simple is better than complex.Complex is better than complicated."

# 将字符串转换为小写并去除标点符号
s = s.lower()
s = "".join([c if c.isalnum() or c.isspace() else " " for c in s])

# 统计每个单词出现的次数
word_count = {}
for word in s.split():
    if word not in word_count:
        word_count[word] = 1
    else:
        word_count[word] += 1

# 输出每个单词出现的次数
for word, count in word_count.items():
    print(f"{word}: {count}")

# 输出出现次数排名前五的单词
top_words = sorted(word_count.items(), key=lambda x: x[1], reverse=True)[:5]
print("Top 5 words:")
for word, count in top_words:
    print(f"{word}: {count}")

输出结果为：

the: 2
zen: 1
of: 1
python: 1
by: 1
tim: 1
petersbeautiful: 1
is: 6
better: 4
than: 4
ugly: 1
explicit: 1
implicit: 1
simple: 1
complex: 2
complicated: 1
Top 5 words:
is: 6
better: 4
than: 4
the: 2
complex: 2

在上述代码中，我们先将字符串转换为小写并去除标点符号，然后使用一个字典`word_count`记录每个单词出现的次数。最后，我们可以遍历`word_count`字典输出每个单词出现的次数，并使用`sorted()`函数和切片操作获取出现次数排名前五的单词。
