7.此函数只接收一个参数且此参数必须是列表数据类型,此函数完成的功能是返回给调用者一个字典,此字典的键值对为此列表的索引及对应的元素。例如传入的列表为:[11,22,33] 返回的字典为 {0:11,1:22,2:33}。

l2 = [11,22,33]
def func8(l1):
    dic = {}
    for i in range(len(l1)):
        dic[i] = l1[i]
    return dic
print(func8(l2))
l2 = [11,22,33]
def func(lst):
    dic = {}
    for i,j in enumerate(l2,0):
        dic[i] = j
    return dic
print(func(l2))
