Python Dictionary Data Type Python dictionary is an ordered collection of items. It stores elements in key/value pairs. Here, keys are unique identifiers that are associated with each value. Let's see an example, # create a dictionary named capital_citycapital_city = {'Nepal':'Kathmandu','I...
A dictionary in Python is an unordered collection of key-value pairs. Each key is unique and maps to a corresponding value. Dictionaries are defined using curly braces {} with key-value pairs separated by a colon (:). Here's an example: my_dict = {"name": "John", "age": 30, "ci...
In this example, we define a simpledataclassPointrepresenting a point in a two-dimensional space. We then create a dictionarydatacontaining the coordinates(3.5, 7.2)of the point. Using thefrom_dict()function from thedacitelibrary, we initialize aPointinstancepointfrom the dictionary data. The prin...
Thepopitem()method is similar to thepop()method for lists. It randomly removes a key and its associated value from the dictionary: Python capitals.popitem() The output is: Output ('Nigeria', ('Abuja', 1235880)) Another example: Python ...
Python dictionaries are flexible objects, allowing you to model complex and related data. In this module, you learned how to: Identify when to use a dictionary. Create and modify data inside a dictionary. Use dictionary methods to access dictionary data. ...

The construct of dictionary implementation in python is more generally known as “Associative array”. Inlistortuples, we can access the items by referencing their index positions because items inside the list are ordered (i.e. Stored in the order they got created). The dictionary objects can...
You can use a dictionary to define headers, and you can send them along with your request using the headers parameter of .get(). For example, say you want to send some request ID to the API server, and you know you can do that using X-Request-Id: Python >>> headers = {"X-Req...
Now when we select columns of a DataFrame, we use brackets just like if we were accessing a Python dictionary. revenue now contains a Series: revenue.head() Out: Title Guardians of the Galaxy 333.13 Prometheus 126.46 Split 138.12 Sing 270.32 Suicide Squad 325.02 Name: revenue_...
