How to check if variable is a python dictionary?
for k,v in dict.items():
if type(v)==dict:
print('This is a dictionary')
This code is not working
Edited:
Solved. type(v) is working. I made mistake when used name 'dict' for my dictionary.
To properly check if v is an instance of a dict you can use isinstance:
for k,v in your_dict.items():
if isinstance(v, dict):
print('This is a dictionary')
Note: Change your variable name 'dict' to something else, as you're masking the buit-in name
To begin with, never name your variables as python keywords, so don't use dict as a python variable name, since it is replacing the python built-in keyword dict. Instead use something like my_dict
You should consider using isinstance to check if a variable is a dictionary, instead of type
From the docs of type:
The isinstance() built-in function is recommended for testing the type of an object, because it takes subclasses into account.
Also since you are only using values, consider only iterating on them using my_dict.values()
for v in my_dict.values():
if isinstance(v, dict):
print('This is a dictionary')
It is better to use isinstance(object, classinfo) than checking if type(object) == classinfo
for k,v in dict.items():
print(isinstance(v, dict))
