实验任务1
源代码：
import random
print('用列表存储随机整数：')
lst = [random.randint(0,100) for i in range (5)]
print(lst)
print('\n用集合存储随机整数： ')
s1 = {random.randint(0,100) for i in range(5)}
print(s1)
print('\n用集合存储随机整数：')
s2 = set()
while len(s2) <5:
s2.add(random.randint(0,100))
print(s2)
运行结果：
问题1:0-99，可以
问题2:0-4，不包括；1-4，不包括
问题3:不一定，集合会自动去除重复元素
问题4:是

text = """The Zen of Python, by Tim Peters
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!"""
