Comment créer des tableaux HTML interactifs à partir de Pandas Dataframe en Python
Comment convertir Pandas Dataframe en tableaux HTML en Python
Découvrez comment créer des tableaux HTML interactifs avec pagination, tri et recherche uniquement à partir d'un cadre de données pandas à l'aide de pandas et de tableaux de données jQuery en Python.
Il existe de nombreux cas où vous devez convertir votre dataframe Pandas en un tableau HTML. L'une des principales raisons est que vous souhaitez mieux visualiser votre ensemble de données en tant qu'analyste de données ou l'intégrer au site Web de votre organisation.
Dans ce didacticiel, nous convertirons n'importe quelle dataframe Pandas en un tableau interactif avec pagination, et nous pourrons effectuer un tri par colonne et une recherche.
Pour commencer, bien sûr, vous devez avoir installé Pandas :
$ pip install pandasImportation des bibliothèques nécessaires :
import pandas as pd
import webbrowserNous utiliserons le module webbrowser pour ouvrir automatiquement le tableau HTML résultant dans un nouvel onglet sur le navigateur par défaut.
Créons une fonction qui accepte le dataframe comme argument et renvoie le contenu HTML pour cela :
def generate_html(dataframe: pd.DataFrame):
# get the table HTML from the dataframe
table_html = dataframe.to_html(table_id="table")
# construct the complete HTML with jQuery Data tables
# You can disable paging or enable y scrolling on lines 20 and 21 respectively
html = f"""
<html>
<header>
<link href="https://cdn.datatables.net/1.11.5/css/jquery.dataTables.min.css" rel="stylesheet">
</header>
<body>
{table_html}
<script src="https://code.jquery.com/jquery-3.6.0.slim.min.js" integrity="sha256-u7e5khyithlIdTpu22PHhENmPcRdFiHRjhAuHcs05RI=" crossorigin="anonymous"></script>
<script type="text/javascript" src="https://cdn.datatables.net/1.11.5/js/jquery.dataTables.min.js"></script>
<script>
$(document).ready( function () {{
$('#table').DataTable({{
// paging: false,
// scrollY: 400,
}});
}});
</script>
</body>
</html>
"""
# return the html
return htmlHeureusement, Pandas a une to_html()méthode intégrée qui génère le contenu HTML de cette trame de données sous forme de tablebalise. Après cela, nous créons une page HTML complète et ajoutons une extension de tables de données jQuery, donc c'est interactif.
Par défaut, la pagination, le tri par colonne et la recherche sont activés ; vous pouvez les désactiver si vous le souhaitez. Par exemple, si vous souhaitez désactiver la pagination et afficher l'intégralité de la trame de données, vous pouvez décommenter paging: false(rappelez-vous que les commentaires en Javascript sont "//"et non "#"comme en Python).
Je saisis cet ensemble de données à des fins de démonstration. Essayons-le :
if __name__ == "__main__":
# read the dataframe dataset
df = pd.read_csv("Churn_Modelling.csv")
# take only first 1000, otherwise it'll generate a large html file
df = df.iloc[:1000]
# generate the HTML from the dataframe
html = generate_html(df)
# write the HTML content to an HTML file
open("index.html", "w").write(html)
# open the new HTML file with the default browser
webbrowser.open("index.html")Après avoir obtenu notre contenu HTML, nous l'écrivons dans un nouveau index.htmlfichier et l'ouvrons avec webbrowser.open()la fonction. Voici à quoi ça ressemble :
Le truc cool, c'est qu'on peut chercher sur la table :
Ou trier par une colonne spécifique :
Ou modifiez les paramètres de pagination, par exemple en affichant 50 entrées par page :
Vous pouvez également voir les pages sous le tableau :
Conclusion
Bien! Voilà pour le tuto. J'espère qu'il vous sera utile de mieux visualiser votre ensemble de données ou de l'intégrer en tant que contenu HTML sur votre site Web.
L'ensemble de données utilisé dans ce didacticiel provient à l'origine de Kaggle . Vous pouvez l'obtenir ici si vous n'avez pas de compte Kaggle.
Notez que le style du tableau ne fonctionnera que si vous disposez d'une connexion Internet. Si vous voulez qu'il fonctionne hors ligne, vous pouvez simplement télécharger les fichiers JS/CSS et les placer dans le répertoire courant afin qu'il les charge à partir de votre machine locale au lieu d'un CDN.

Lambda, Map, Filter functions in python
Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.
Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is
Syntax: x = lambda arguments : expression
Now i will show you some python lambda function examples:
#python #anonymous function python #filter function in python #lambda #lambda python 3 #map python #python filter #python filter lambda #python lambda #python lambda examples #python map

Python Pandas Objects - Pandas Series and Pandas Dataframe
In this post, we will learn about pandas’ data structures/objects. Pandas provide two type of data structures:-
Pandas Series
Pandas Series is a one dimensional indexed data, which can hold datatypes like integer, string, boolean, float, python object etc. A Pandas Series can hold only one data type at a time. The axis label of the data is called the index of the series. The labels need not to be unique but must be a hashable type. The index of the series can be integer, string and even time-series data. In general, Pandas Series is nothing but a column of an excel sheet with row index being the index of the series.
Pandas Dataframe
Pandas dataframe is a primary data structure of pandas. Pandas dataframe is a two-dimensional size mutable array with both flexible row indices and flexible column names. In general, it is just like an excel sheet or SQL table. It can also be seen as a python’s dict-like container for series objects.

Pandas in Python
Pandas is used for data manipulation, analysis and cleaning.
What are Data Frames and Series?
Dataframe is a two dimensional, size mutable, potentially heterogeneous tabular data.
It contains rows and columns, arithmetic operations can be applied on both rows and columns.
Series is a one dimensional label array capable of holding data of any type. It can be integer, float, string, python objects etc. Panda series is nothing but a column in an excel sheet.
How to create dataframe and series?
s = pd.Series([1,2,3,4,56,np.nan,7,8,90])
print(s)
How to create a dataframe by passing a numpy array?
- d= pd.date_range(‘20200809’,periods=15)
- print(d)
- df = pd.DataFrame(np.random.randn(15,4), index= d, columns = [‘A’,’B’,’C’,’D’])
- print(df)

Python for Beginners #2 — Importing files to python with pandas
Use pandas to upload CSV, TXT and Excel files
Story time before we begin
Learning Python isn’t the easiest thing to do. But consistency is really the key to arriving at a level that boosts your career.
We hear a lot about millennials wanting things to easy. In reality, there are a lot of young professionals who believe that they can do more for their companies but are being held back by the work cultures they are faced with at the onset of their careers.
Having been lucky enough to have found a job after my studies, I remember immediately feeling a wave of disappointment a very short while after starting my new job. I felt like a cog in a massive machine. I wasn’t really anything other than a ‘resource’. An extra 8–15 hours of daily man power depending on my boss’ whim.
The result, was the eventual disenchantment and lack of motivation simply because, for the most part, I was expected to be quiet and do my job in the hope of one day being senior enough to effect significant changes. And while the older generation would generally tell me to suck it up, I couldn’t see myself sucking it up for 5 years or more. I knew I’d get stale and afraid of change, much like those telling me to stay in my place.
For anyone in a similar situation,**_ do your best to improve on your skills _**and find an environment that works for you. That’s the whole purpose of these articles. To get you on your way to freedom.
Introduction
For this demonstration, I’ll use data from this Kaggle competition. It’s a simple CSV file containing data on individuals in the Titanic and the different profiles i.e. (age, marital status etc.)
I want to import this file to python. I’ll show you how to do this alongside all the possible troubleshoots you may encounter.
