Welcome folks today in this blog post we will be building a language translator app using translate module in tkinter gui desktop app in python. All the full source code of the application is given below.

Get Started

In order to get started you need to install the below library using the pip command as shown below

pip install tkinter

pip install translate

After installing this library you need to make an app.py file and copy paste the following code

app.py

from tkinter import *
from translate import Translator

#Translator function 
def translate():
    translator= Translator(from_lang=lan1.get(),to_lang=lan2.get())
    translation = translator.translate(var.get())
    var1.set(translation)

#Tkinter root Window with title
root = Tk()
root.title("Translator")

#Creating a Frame and Grid to hold the Content
mainframe = Frame(root)
mainframe.grid(column=0,row=0, sticky=(N,W,E,S) )
mainframe.columnconfigure(0, weight = 1)
mainframe.rowconfigure(0, weight = 1)
mainframe.pack(pady = 100, padx = 100)

#variables for dropdown list
lan1 = StringVar(root)
lan2 = StringVar(root)

#choices to show in dropdown menu
choices = { 'English','Hindi','Gujarati','Spanish','German'}
#default selection for dropdownlists
lan1.set('English')
lan2.set('Hindi')

#creating dropdown and arranging in the grid
lan1menu = OptionMenu( mainframe, lan1, *choices)
Label(mainframe,text="Select a language").grid(row = 0, column = 1)
lan1menu.grid(row = 1, column =1)

lan2menu = OptionMenu( mainframe, lan2, *choices)
Label(mainframe,text="Select a language").grid(row = 0, column = 2)
lan2menu.grid(row = 1, column =2)

#Text Box to take user input
Label(mainframe, text = "Enter text").grid(row=2,column=0)
var = StringVar()
textbox = Entry(mainframe, textvariable=var).grid(row=2,column=1)

#textbox to show output
#label can also be used
Label(mainframe, text = "Output").grid(row=2,column=2)
var1 = StringVar()
textbox = Entry(mainframe, textvariable=var1).grid(row=2,column=3)

#creating a button to call Translator function
b=Button(mainframe,text='Translate',command=translate).grid(row=3,column=1,columnspan=3)

root.mainloop()

If you execute the above python script by typing the below command

python app.py
