第三次作业

一.列表，元组，字典，集合的遍历

#列表的遍历
List1=['Tracy',20,'Amy',10]
print(List1)
for a in List1:
    print(a)
#元组的遍历
Tuple1=('你今天真好看')
print(Tuple1)
for b in Tuple1:
    print(b)
#集合的遍历
Set1={1,2,3,4}
print(Set1)
for c in Set1:
    print(c)
#字典的遍历
dict1 = {'a':80,'b':79,'c':90}
print(dict1)
for d in dict1:
    print(d,dict1[d])

运行结果

str1=str1.lstrip()
print(str1)
#把单词全部变成小写
a=str1.lower()
print(a)
#将歌词的每个单词分隔
strList=str1.split()
print(len(strList),strList)
#用set把字符串转换成集合
strSet=set(strList)
#计算每个单词出现的次数
for word in strSet:
   print(word,strList.count(word))
