Voraussetzungen: Einführung in tkinter | Sentiment Analysus mit Vader

Python bietet mehrere Optionen zum Entwickeln einer grafischen Benutzeroberfläche (GUI). Von allen GUI-Methoden ist Tkinter die am häufigsten verwendete Methode. Python mit Tkinter gibt den schnellsten und einfachsten Weg aus, um GUI-Anwendungen zu erstellen. In diesem Artikel erfahren Sie anhand einer schrittweisen Anleitung, wie Sie mit Tkinter eine GUI-Anwendung für den Sentiment Detector erstellen.
 

So erstellen Sie einen tkinter:

• Modul importieren - tkinter
• Erstellen Sie das Hauptfenster (Container)
• Fügen Sie dem Hauptfenster eine beliebige Anzahl von Widgets hinzu.
• Wenden Sie den Ereignisauslöser auf die Widgets an.

Die GUI würde wie folgt aussehen:

Lassen Sie uns eine GUI-basierte Sentiment Detector-Anwendung erstellen, die die vom Benutzer angegebenen Gefühle in Bezug auf die angegebenen Sätze anzeigen kann.
 

Unten ist die Implementierung: 

from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer 
 
from tkinter import *
 
def clearAll() : 
   
    
    negativeField.delete(0, END) 
    neutralField.delete(0, END) 
    positiveField.delete(0, END) 
    overallField.delete(0, END) 
 
    
    textArea.delete(1.0, END)
     
def detect_sentiment():
 
    
    sentence = textArea.get("1.0", "end")
 
    
    sid_obj = SentimentIntensityAnalyzer() 
 
    
    
    
    sentiment_dict = sid_obj.polarity_scores(sentence) 
 
    string = str(sentiment_dict['neg']*100) + "% Negative"
    negativeField.insert(10, string)
     
 
    string = str(sentiment_dict['neu']*100) + "% Neutral"
    neutralField.insert(10, string)
 
    string = str(sentiment_dict['pos']*100) +"% Positive"
    positiveField.insert(10, string)
     
    
    if sentiment_dict['compound'] >= 0.05 :
        string = "Positive"
 
    elif sentiment_dict['compound'] <= - 0.05 :
        string = "Negative"
