在循环字典中分配值(Assigning values in looped dictionary)

 我正在努力解决这个循环，我想为嵌套字典赋值。 我有一个名为stp2的列表和一个默认的dict，我创建时没有作为值。 我试图逐个获取列表元素并分配给字典。 
 
stp2=['Anna', 'William', 'Mary', 'Ben', 'Richard','Calvin', 'Rock']
 
 而my_dict是默认的dict（嵌套），如下所示： 
 
defaultdict(<class 'dict'>, {0: {'name': None, 'price': None,}, 1:{'name': None, 'price': None,}, 2: {'name': None, 'price': None,}, 3: {'name': None, 'price': None,}, 4: {'name': None, 'price': None,}, 5: {'name': None, 'price': None,}, 6: {'name': None, 'price': None,}})
 
 我正在使用此循环来更新值： 
 
for z in enumerate(stp2):
 my_dict[z[0]]['name']=z[1]

print(my_dict)
 
 理想情况下我的输出应该是这样的，但我在重复的每一个值中得到“摇滚”。 
 
 理想输出： 
 
{0: {'name': 'Anna', 'price': None,}, 1:{'name': 'William', 'price': None,}, 2: {'name': 'Mary', 'price': None,}, 3: {'name': 'Ben', 'price': None,}, 4: {'name': 'Richard', 'price': None,}, 5: {'name': 'Calvin', 'price': None,}, 6: {'name': 'Rock', 'price': None,}}
 
 感谢你的帮助。 

I am struggling with this loop where I want to assign values to a nested dictionary. I have a list called stp2 and a default dict that I created with none as values. I am trying to take list elements one by one and assign to the dictionary.
 
stp2=['Anna', 'William', 'Mary', 'Ben', 'Richard','Calvin', 'Rock']
 
whereas my_dict is a default dict (nested) which looks like this:
 
defaultdict(<class 'dict'>, {0: {'name': None, 'price': None,}, 1:{'name': None, 'price': None,}, 2: {'name': None, 'price': None,}, 3: {'name': None, 'price': None,}, 4: {'name': None, 'price': None,}, 5: {'name': None, 'price': None,}, 6: {'name': None, 'price': None,}})
 
I am using this loop to update values:
 
for z in enumerate(stp2):
 my_dict[z[0]]['name']=z[1]

print(my_dict)
 
My output should ideally look like this but I am getting "Rock" in every value repeated.
 
Ideal output: 
 
{0: {'name': 'Anna', 'price': None,}, 1:{'name': 'William', 'price': None,}, 2: {'name': 'Mary', 'price': None,}, 3: {'name': 'Ben', 'price': None,}, 4: {'name': 'Richard', 'price': None,}, 5: {'name': 'Calvin', 'price': None,}, 6: {'name': 'Rock', 'price': None,}}
 
Appreciate your help.
