我创建了一个word_name的字典，我希望这个字典每次生成的随机内容都可以生成一个独立的字典，然后将这些字典归到word_all字典中进行存储
#!/usr/bin/python3
import random


def create_word():
    i = 0
    word_name = {}
    word_all = {}
    word_num = random.randint(0,100)

    while i < word_num:
        a = 'a'+str(i)
        xx = {a:123}
        word_name.update(xx)
        i = i + 1

    print(word_name)

create_word()

是这样吗？

import random
 
 
def create_word():
    i = 0
    word_name = {}
    word_all = {}
    word_num = random.randint(0,100)
 
    while i < word_num:
        a = 'a'+str(i)
        xx = {a:random.randint(0,100)}
        word_name.update(xx)
        i = i + 1
 
    print(word_name)
 
create_word()

关键是你大字典的键是什么？值又是什么呢？

是想让它变成嵌套字典，比如{a:{xxx:111,sss:222},b:{zzz:222,sss:333}}
