Python – A Revolution in Web Development

What is Python?
Python is a programming language developed by Guido Van Rossum. Python is most praised for its neat syntax and readable code, if you want to build a career in development field then Python is best for you to start with. It allows you to do everything with GUI development, web application, system administration tasks, financial calculation, data analysis, visualization and goes on.

Interpreted Language:
Python is interpreted language, it is an interpreter program that parses python program line by line basis, as compared to compiled languages like C or C++, where compiler first compiles the program and then start running.

You must be thinking so what’s the difference?
Interpreted languages are bit slower as compared to compiled languages. You will surely get some performance benefits if you write your code in compiled languages like C or C++.
It is a daunting task for a beginner to write a code in such languages. You need to write most basic functions like calculate the length of the array, split the string etc. Sometimes you need to generate your own data structures to encapsulate data in advance programs. In C or C++ before you start solving your issues you must take care of all minor details.
This is where Python comes, you don’t need to define any data structure, or there is no need to define small utility functions because python has everything to get you started.
Additionally, there are hundreds of libraries of python available at https://pypi.python.org/ which you can use in your project.

Python is dynamically typed
You don’t require defining variable data type ahead of time, python automatically guesses the data type of the variable based on the type of value it contains.
For e.g
myvar = “Hello World”
In the above statement “Hello World” is assigned to myvar , so the type of myvar is a string.
In python, you don’t require to end a statement with a semicolon ( ;).
Now suppose later in program we will assign myvar a value of 1 i.e
myvar = 1
Now myvar is of type int

Python is strongly typed
If you ever programmed in PHP or javascript. You may have noticed that they both convert data of one data type to other data types automatically.
For e.g:
In JavaScript
1 + “2”
Will be ’12’
Here 1 will be converted to a string and concatenated to “2”, which results in ’12’, which is a string. In Python automatic conversions are not allowed, so
1 + “2”
Will produce an error.

Write less code and do more
Python codes are generally 1/3 or 1/5 of the java code. It means we can write less code in Python to achieve the same target in Java.
In python to read a file you need just 2 lines:
with open(“myfile.txt”) as f:
print(f.read())

How did I start programming in Python?
Any program you want to build such as GUI applications, create websites, scrape data from website, and analyze data, system administration task, game development and more.

Laravel – Database Migrations 2018

Laravel offers an easy to use and influential way to create database structure using code. This method allows you to define your database tables and columns in text files, which makes it easy to edit and develop as needed. Laravel also provides a built-in-rollback technique that allows a user to revert back any database structure changes as required. We are sharing useful knowledge about Laravel database migrations and how to use them.

Project:

We are giving example for restaurant review portal, users will be able to submit restaurant reviews using a PHP form, and view existing restaurant reviews that stored in a MySQL database.

Requirement:
A 1&1 Cloud Server with Laravel and PHP 7.0+ installed.
Create the Database:
Firstly, you require creating a database for your project, and a database user for Laravel to use. Log in to the MySQL client:
MySQL -u root –p

Create a database of the reviews:
CREATE DATABASE reviews_db;
The subsequent command will create a user review_site with password JxSLRkdutW and allow the user to access the reviews_db database:
GRANT ALL ON reviews_db.* to review_site@localhost IDENTIFIED BY ‘JxSLRkdutW’;

Create the Laravel Project:
Use su to switch to your Laravel user:
su – jdoe

Go to your web directory:
cd /var/www/html
Create the Laravel project:
laravel new reviews
It will create the reviews directory. Move into this directory:
cd reviews
Now, set the MySQL credentials in the Laravel environment file. Open the .env file for editing:
nano .env
Find the section which reads:
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret
Change the DB_DATABASE, DB_USERNAME, and DB_PASSWORD lines to contain your project’s MySQL database name, username, and password:
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=reviews_db
DB_USERNAME=review_site
DB_PASSWORD=JxSLRkdutW
Save and exit the file.
Create and Run the Migration
Laravel migrations work as a version control system for your database. It will allow a user to easily collaborate and edit database design.
Use the make:migration Artisan command to create a migration named create_reviews_table. We will also include the –create flag to create the table user_reviews:
php artisan make:migration create_reviews_table –create=user_reviews
The new migration will be situated in the database/migrations directory, and will have a name which includes the timestamp:

jdoe@localhost:/var/www/html/reviews$ ll database/migrations
total 20
drwxrwxr-x 2 jdoe jdoe 4096 Oct 26 16:16 ./
drwxrwxr-x 5 jdoe jdoe 4096 Oct 26 16:15 ../
-rw-rw-r– 1 jdoe jdoe 746 Oct 26 16:15 2014_10_12_000000_create_users_table.php
-rw-rw-r– 1 jdoe jdoe 683 Oct 26 16:15 2014_10_12_100000_create_password_resets_table.php
-rw-rw-r– 1 jdoe jdoe 602 Oct 26 16:16 2017_10_26_161616_create_reviews_table.php
All migration class includes two methods: up() and down(). The up() method will add new architecture (tables, columns, indexes, etc.) to the database. The down() method will reverse operations which have been performed by the up() method.

Open the database migration file for editing:
nano database/migrations/2017_10_26_161616_create_reviews_table.php
All migration automatically includes the auto-incrementing id column and the timestamps() columns. So we are adding three columns to the table:
reviewer_name: A string with a maximum of 100 characters.
star_rating: An integer.
details: A text field.
For a full list of column types, check the official Laravel documentation on migrations.
Locate the up() method section in the migration file:
public function up()
{
Schema::create(‘user_reviews’, function (Blueprint $table) {
$table->increments(‘id’);
$table->timestamps();
});
}
Add the new column definitions so that this section reads:
public function up()
{
Schema::create(‘user_reviews’, function (Blueprint $table) {
$table->increments(‘id’);
$table->timestamps();
$table->string(‘reviewer_name’, 100);
$table->integer(‘star_rating’);
$table->text(‘details’);
});
}
Save and exit the file. Then run the migration:
php artisan migrate
If you need to revert (roll back) a migration, use the command:
php artisan migrate:rollback
