Python TypeError: 'dict' object is not callable Solution

Items in a Python dictionary must exist called using the indexing syntax. This ways you must follow a dictionary with square brackets and the fundamental of the item you lot want to admission. If you endeavour to use curly brackets, Python will render a "TypeError: 'dict' object is non callable" error.

In this guide, we talk about this error and why it is raised. Nosotros walk through an instance of this error in activeness then you lot can larn how to solve information technology in your lawmaking.

TypeError: 'dict' object is not callable

Dictionaries are iterable objects. This ways that yous tin access items individually from inside a dictionary.

To access an item in a dictionary, y'all demand to use indexing syntax. Hither'south an example of indexing syntax in Python: 

dictionary = {"key1": "value1"} print(dictionary["key1"])

Run our lawmaking. "value" is returned. The value associated with the fundamental "key1" is "value1".

If nosotros endeavor to access an item from our dictionary using curly brackets, nosotros encounter an mistake. This is because curly brackets are used to announce function calls in Python.

When Python sees a pair or curly brackets, information technology thinks you are trying to execute a function.

An Example Scenario

Here, we create a programme that prints out all the values in a dictionary to the panel. This dictionary contains information about a type of bird, the Starling.

Beginning by declaring a dictionary: 

starling = { 	"proper noun": "Starling", 	"Scientific_name": "Sturnus Vulgaris", 	"conservation_status_uk": "Cherry-red", 	"food": "Invertebrates and fruit" }

This dictionary has four keys and four values. Let's use impress() statements to impress each value from our dictionary to the console: 

print("Proper noun: " + starling("name")) print("Scientific Name: " + starling("scientific_name")) impress("United kingdom Conservation Condition: " + starling("conservation_status_uk")) print("What They Eat: " + starling("food"))

This code should print out the values of "name", "scientific_name", "conservation_status_uk", and "food" to the console. Run our code and see what happens: 

Traceback (nearly recent telephone call terminal):   File "principal.py", line 8, in <module> 	impress("Name: " + starling("name")) TypeError: 'dict' object is not callable

Our code returns an error.

This is because nosotros are incorrectly accessing items from our dictionary. Dictionary items must be accessed using indexing syntax. In our lawmaking above, we've tried to utilise curly brackets to admission items in our dictionary.

The Solution

To solve this error, nosotros need to brand sure we use foursquare brackets to access items in our dictionary. Every time nosotros access an particular from the 'starling" lexicon, we should use this syntax:

Venus, a software engineer at Rockbot

"Career Karma entered my life when I needed information technology virtually and speedily helped me match with a bootcamp. Two months afterward graduating, I found my dream chore that aligned with my values and goals in life!"

Venus, Software Engineer at Rockbot

Use this syntax in our master program: 

impress("Name: " + starling["proper name"]) print("Scientific Proper name: " + starling["scientific_name"]) impress("United kingdom of great britain and northern ireland Conservation Condition: " + starling["conservation_status_uk"]) impress("What They Eat: " + starling["food"])

Our lawmaking now functions successfully: 

Proper noun: Starling Scientific Name: Sturnus Vulgaris UK Conservation Status: Red What They Eat: Invertebrates and fruit

Instead of using curly brackets to access items in our dictionary, we have used foursquare brackets. Square brackets indicate to Python that we desire to admission items from an iterable object. Curly brackets, on the other mitt, indicate a function call.

Determination

The "TypeError: 'dict' object is non callable" error is raised when yous try to use curly brackets to admission items from within a lexicon. To solve this mistake, make sure you use the proper square bracket syntax when you try to access a dictionary item.

Now yous have all the knowledge y'all need to set this error in your Python code !
