[PYTHON] WEB application development using django-Development environment construction-

Introduction

I challenged a simple voting WEB application tutorial using django, which is one of the WEB application frameworks that is interested in WEB applications and can be easily created.

environment

• windows 10
• python 3.7.1
• VScode

Prepare the environment (what to install)

--python is premised on installation --Install pip --Install Django --Install virtualenv

Installation

pip installation

――Pip is a tool that makes it easy to install various packages. --Download pip (executed at command prompt, cmd below)

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

Get-pip.py is stored in the directory where the command is executed. * By default, it is under the user

--Installing pip

python get-pip.py

If "Successfully installed ..." is displayed, the installation is complete.

virtualenv installation

--Virtualenv is software for running virtual environment. This time I'll run Django in a virtual environment. --Install virtualenv

pip install virtualenv

--Create a virtual environment

It can be anywhere, but prepare a "Python" folder in advance. This time, create it directly under the C drive. After creating, move to the directory with cmd.

cd C:\Python

Once moved, create a virtual environment.

virtualenv env1

When the creation is complete, change to the "env1" directory.

cd env1

Once moved, activate the virtual environment.

Scripts/activate

Once enabled, you should see something like this:

(env1) C:\Python\env1>

Django installation

--Install Django.

Make sure that the virtual environment is enabled before executing.

pip install django

If "Successfully installed ..." is displayed, the installation is complete.

--Confirm that Django is installed successfully

pip freeze

The version of Django and other related software will be output as shown below.

asgiref==3.2.10
Django==3.1
pytz==2020.1
sqlparse==0.3.1

--Exit the command prompt After confirming the above, exit the command prompt once.

Disable the virtual environment.

deactivate

Exit the command prompt.

exit

Django operation check

--Confirmation that it works normally (implemented with cmd)

Change to the directory.

cd C:\Python\env1

Once moved, activate the virtual environment. Scripts/activate

Once enabled, put it in interactive mode (interpreter).

python

Once launched, import Django. Type the following commands, and then press Enter line by line.

>import django
>print(django.get_version())

If the Django version is displayed as shown below, the operation check is complete.
