Question

说我有一本这样的字典：

profile = {'Person':{'name':['John'], 'Description':['smart']}}

我正在寻找一段代码来搜索“ John”和“ Description”，但不知道它们在嵌套字典中的位置。我也想在代码中打印出这样的内容：

John is located in the value of profile['Person']
Description is located in the key of profile['Person']

我该怎么做？任何帮助将不胜感激。谢谢

了解如何iterate浏览嵌套词典。在Python字典中，items()方法用于返回带有所有带有值的字典键的列表。索引[]用于访问嵌套字典的元素

profile = {'Person':{'name':['John'], 'Description':['smart']},'Person1':{'name':['John1'], 'Description':['smart1']}}

for p_id, p_info in profile.items():
    for key in p_info:

        if p_info[key][0] == "John":
            print(p_info[key][0],"is located in the value of profile['",p_id,"']")
        if p_info[key][0] == "smart":
            print(p_info[key][0],"is located in the value of profile['",p_id,"']")
