如何检查变量是否是python中的字典？

How would you check if a variable is a dictionary in python?

例如，id就像循环遍历字典中的值，直到找到一个字典循环通过它找到的：

For example id like it to loop through the values in the dictionary till it finds a dictionary then loop through the one it finds:

dict = {'abc':'abc','def':{'ghi':'ghi','jkl':'jkl'}}
for k, v in dict.iteritems():
    if ###check if v is a dictionary:
        for k, v in v.iteritems():
            print(k,' ',v)
    else:
        print(k,' ',v)

任何帮助将不胜感激。

推荐答案

p>如果type（ele）是dict 或使用 ifinstance> isinstance（ele，dict），如果您已经子类化 dict ：

You could use if type(ele) is dict or use isinstance(ele, dict) which would work if you had subclassed dict:

d = {'abc':'abc','def':{'ghi':'ghi','jkl':'jkl'}}
for ele in d.values():
    if isinstance(ele,dict):
       for k, v in ele.items():
           print(k,' ',v)
