How do I check if a value is a dictionary with a specific key in Python?Antek N
To check if a value is a dictionary with a specific key in Python, you can use theisinstance()
function to check if the value is of typedict
, and then use thein
operator to verify if the specific key is present in the dictionary.
Here's an example of how you can perform this check:
1 2 3 4 5 6 7 8 9 10 11
def is_dict_with_key(value, key): return isinstance(value, dict) and key in value # Usage: my_dict = {"name": "John", "age": 25} if is_dict_with_key(my_dict, "name"): print("The value is a dictionary with the key 'name'.") else: print("The value is either not a dictionary or does not have the key 'name'.")
In the above code, theis_dict_with_key()
function takes two parameters:value
, representing the value to check, andkey
, representing the specific key to verify in the dictionary.
The function first usesisinstance(value, dict)
to check ifvalue
is of typedict
. This ensures thatvalue
is indeed a dictionary object. Then, it
