This series will show you how to develop web applications using Python libraries such as Flask and Django.
Learn how to analyze Time Series data with ARIMA in Python.
❌ Don't think of a for loop if you want to summarise your daily Time Series by years. ✅ Instead, use the function resample() from pandas. Let me explain it with an example. We start by loading a DataFrame from a CSV file that contains information on ...
Learn everything about filtering specific parts of the DataFrame based on conditions.
Read this story to learn the roadmap you could follow to get a python job where you can take your skills to the next level while you get paid.
Challenge Importance The time has come to add another layer to the hierarchy of Machine Learning models. Do we have the variable we want to predict in the dataset? YES: Supervised Learning Predicting a Numerical Variable → Regression Predicting a C...

What do I need to start a
Djangoproject?
Anaconda installed. If not, click here to download & installYou need to install the library in your terminal (use Anaconda Prompt for Windows Users):
conda create -n django_env django
conda activate django_env
Ok, you got it. What's next?
What should I do within VSCode?
Django CLI installed with the Django package alreadyType the following line within the terminal:
django-admin startproject shop
What should I see on my computer after this?
user folder, you will see thatshop has been createddrag & drop it to VSCode
- shop/
- manage.py
- shop/
- __init__.py
- settings.py
- urls.py
- asgi.py
- wsgi.py
Do I need to study all of them?
Ok, what's the next step?
terminal and write the following ↓cd shop
python manage.py runserver
web browserlocalhost and you should see something like this ↓What if I try another
URLlike http://127.0.0.1:8000/products?
How can I tell that to Django?
shop Django ProjectWith the following line of code ↓
python manage.py startup products
shop > urls.pyfrom django.contrib import admin
from django.urls import path, include # modified
urlpatterns = [
path('products/', include('products.urls')), # added
path('admin/', admin.site.urls),
]
Create a View (HTML Code) to be recognised when you go to the URL http://127.0.0.1:8000/products
Within the file shop > products > views.py
from django.http import HttpResponse
def view_for_products(request):
return HttpResponse("This function will render `HTML` code that makes you see this <p style='color: red'>text in red</p>.")
See this tutorial if you want to know a bit more about HTML
Call the function view_for_products when you click on http://127.0.0.1:8000/products
You need to create the file urls.py within products → shop > products > urls.py
from django.urls import path
from . import views
urlpatterns = [
path('', views.view_for_products, name='index'),
]
Why do we reference the
URLsin two files? One inshop/urls.pyfolder and the other inproducts/urls.py?
Django project separated by different Appsproducts Appshop/urls.py, you reference the products.py URLs here ↓urlpatterns = [
path('products/', include('products.urls')), #here
path('admin/', admin.site.urls),
]
https://127.0.0.1:8000/productsshop/products/urls.pyshop/products/views.py ↓
def new_view(request):
return HttpResponse('This is the <strong>new view</strong>')
shop/products/urls.pyfrom django.urls import path
from . import views
urlpatterns = [
path('', views.view_for_products, name='index'),
path('pepa', views.new_view, name='pepa'), # new url
]
shop/urls.py sinceshop/products/urls.py at the time we wroteinclude('products.urls') in the file shop/urls.pySo, each time I want to create a different
HTML, do I need to create a View?
Yes, it's how the Model View Template (MVT) works ↓
You introduce an URL
URL activates a ViewHTML code gets rendered in the websiteWhy don't you mention anything about the
model?
Any doubts?
