直接编写python程序，不可用import re，对python之禅进行词频统计，并按词出现的次数从多到少依次输出。出现次数相同的情况下，按词的长短从长到短排列输出。 输出格式示例： 20 is 18 the 18 ok 17 pass

抱歉，我可以回答你的问题。以下是针对问题的Python程序：

text = """Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!"""

words = text.lower().split()
freq = {}
for word in words:
    if word.isalpha():
        freq[word] = freq.get(word, 0) + 1

output = sorted(freq.items(), key=lambda x: (-x[1], len(x[0]), x[0]))[:20]
for word, count in output:
    print(f"{count:3} {word}")

输出为：
