python基础知识-集合，列表，元组间的相互装换

在python中列表，元祖，集合间可以进行相互转化，

def main():
    set1={'hello','good','banana','zoo','Python','hello'}
    print(len(set1))
    x=sorted(set1)
    print(type(x))
    print(x)
    list1=list(set1)
    print(list1)
    list2=[1,2,3,1,2,4]
    set2=set(list2)
    print(set2)
    tuple1=(1,1,2,3,4,4)
    list3=list(tuple1)
    print(list3)
    set3=set(tuple1)
    print(set3)

if __name__ == '__main__':
    main()
结果：
5
<class 'list'>
['Python', 'banana', 'good', 'hello', 'zoo']
['banana', 'hello', 'zoo', 'good', 'Python']
{1, 2, 3, 4}
[1, 1, 2, 3, 4, 4]
{1, 2, 3, 4}
