I can see the first leaf falling

It's all yellow and nice

It's so very cold outside

Like the way I'm feeling inside

But I do do feel

that I too too will miss you much

Miss you much.

Outside it's now raining

And tears are falling from my eyes

Why did it have to happen

Why did it all have to end

In a big big world

But I do do feel

that I too too will miss you much

Miss you much.

I have your arms around me ooooh like fire

But when I open my eyes

You're gone.

Miss you much.

In a big big world

It's not a big big thing if you leave me

strList = strBig.split()
print(len(strList),strList)

print(strBig.lower())#将所有大写转换为小写

strSet = set(strList)
print(len(strSet),strSet)

strDict = {}
for word in strSet:
    strDict[word] = strList.count(word)

print(strDict.items())
print(len(strDict),strDict)


print(strDict['big'])
print(len(strDict),strDict)


strListSort = strList.sort()
print(strListSort)
print(strList)

for word in strList:
    print(word,strList.count(word))

2.列表，元组，字典，集合的遍历

 

classmates = ['Michael','Bob','Tracy','李三','Tracy',56]
new = ['Rose','Jack']
classmates.insert(2,'Tom')#插入
classmates.append('Jack')#追加
classmates.extend(new)#扩展
classmates.pop(-1)#
print(classmates)
classmatesSet = set(classmates)

classmatesSet.add('Jack')
classmatesSet.remove('Bob')
print(classmatesSet)

print(list('abcdef'),tuple('abcdef'))



classmates = ['Tracy','Bob','Tracy','李三','Tracy',56]
score = [85,90,50,60]
cs = dict(zip(classmates,score))
print(cs)


s = {1,2,3}
s.add(4)#增加
print(s)
s.remove(4)#删除
print(s)
s = set([1, 1, 2, 2, 3, 3])#生成
print(s)
#集合运算
s1 = set([1, 2, 3])
s2 = set([2, 3, 4])
print(s2-s1)
