In this Python tutorial, you will learn about some essentials of Python. The topics that we are going to discuss are:
- Multiline Statements
- Naming Convention
Hellow Programmers, In this python tutorial I am gonna talk about variables & their types. So What is Variable?
Variable: Think about an empty pot in which you can put anything. In programming we call it variable. Actually a variable is an empty memory location to store values.
Declaring a variable in python is a piece of cake. Name it & put a value into it. As python is a dynamically typed language we don't need to declare variable types. Python is smart enough to detect the type itself.
There are some rules of declaring variables:
Hello geeks, in this python 3 tutorial, you are going to learn A to Z of Python dictionary. We will discuss the followings:
So, without further ado let’s jump into it.
Python dictionary is a data type of python programming language. It stores data by mapping them with a key. Data are stored in “Key-Value” pairs where each “Key” must be unique. Lists, Tuples can also be stored as value in a dictionary.
We have discussed how to create a Django project and Django app in our first Django tutorial. In this tutorial, we will talk about Django models. We will cover the following topics:
Model is a structure for storing data. The model handles everything related to data. Such as: data access, data validation, dealing with data of other models, etc. It mirrors the fields and behaviors of the data. Generally a model is implemented as a python class which is a subclass of django.db.models.Model. Django gives an automatically-generated database-access API to create a table in our database by each model, and the "attributes" of the table are created by the "fields" of the model class. Models are defined inside an app’s ‘models.py’ file.
