Here's how to create a Carbon Footprint Calculator.


Code:

import tkinter as tk

from tkinter import *

root = tk.Tk ()

root.geometry ( " 700 x 500 " )

root.configure ( bg = " light blue " )

label=tk.Label ( root , text = " CARBON FOOTPRINT CALCULATOR " , font = ( " Times new roman " , 45 ) , bg = " black " , fg = " white " )

label.pack()


x = PhotoImage ( file = " cf.png " )

label = tk.Label ( root , image = x )

label.place ( x = 900 , y = 200 )


label1=tk.Label ( root , text = " Name : " , font = ( " Times new roman " , 15 ) )

label1.place ( x = 0 , y = 160 )

entry1 = tk.Entry ( root )

entry1 . place ( x = 100 , y = 165 )


label2=tk.Label ( root , text = " What is monthly electricity (in units) consumed: " , font = ( " Times new roman " , 15 ) )

label2.place ( x = 0 , y = 200 )

entry2 = tk.Entry ( root )

entry2.place ( x = 415 , y = 205 )


label3 = tk.Label ( root , text = "What is monthly gas (in units) consumed:  " , font = ( " Times new roman " , 15 ) )

label3.place ( x = 0 , y = 240 )

entry3 = tk.Entry ( root )

entry3.place ( x = 365 , y = 245 )


label4 = tk.Label ( root , text = " What is total yearly mileage of car and estimate of public transport used: " , font = ( " Times new roman " , 15 ) )

label4.place ( x = 0 , y = 280 )

entry4 = tk.Entry ( root )

entry4.place ( x = 610 , y = 285 )


label5 = tk.Label ( root , text = " What is the total number of flights taken in the past year (4 hours or less): " , font = ( " Times new roman " , 15 ) )

label5.place ( x = 0 , y = 320 )

entry5 = tk.Entry ( root )

entry5.place ( x = 610 , y = 325 )


label6 = tk.Label ( root , text = " What is the total number of flights taken in the past year (more than 4 hours): " , font = ( " Times new roman " , 15 ) )

label6.place ( x = 0 , y = 360 )

entry6 = tk.Entry ( root )

entry6.place ( x = 630 , y = 365 )


label7 = tk.Label ( root , text = " Press 1 if you recycle newspaper else press 0: " , font = ( " Times new roman " , 15 ) )

label7.place ( x = 0 , y = 400 )

entry7 = tk.Entry ( root )

entry7.place ( x = 400 , y = 405 )


label8 = tk.Label ( root , text = " Press 1 if you recycle aluminium and tin else press 0: " , font = ( " Times new roman " , 15 ) )

label8.place ( x = 0 , y = 440 )

entry8 = tk.Entry ( root )

entry8.place ( x = 455 , y = 445 )

total = 0

def subb():

    global total

    total = 0

    value1 = entry1.get()

    value2 = float( entry2.get() )

    total = total + ( value2*105 )

    value3 = float ( entry3.get() )

    total = total + ( value3*105 )

    value4 = float ( entry4.get() )

    total = total + ( value4*79 )

    value5 = float ( entry5.get() ) 

    total = total + ( value5*1100 )

    value6 = float ( entry6.get() )

    total = total + ( value6*4400 )

    value7 = int ( entry7.get() )

    if ( value7==0 ):

        total = total+184

    value8 = int ( entry8.get() )

    if ( value7==0 ) :

        total = total+166

    if( total<=15999 ):

        label9 = tk.Label ( root , text = f " Hi {value1}. Your Carbon Footprint is : {total}                  pounds/year. Good job, you're carbon footprint is ideal" , font = ( " Times new roman "          , 15 ) )

        label9.place ( x = 0 , y = 530 )

    if ( total > 15999 and total < 22000 ):

        label10 = tk.Label ( root , text = f " Hi {value1}. Your Carbon Footprint is : {total}                pounds/year. You're carbon footprint is average but lets work on reducing it " , font =            ( " Times new roman " , 15 ) )

        label10.place ( x = 0 , y = 530 )

    if ( total > 22000 ) :

        label11 = tk.Label ( root , text = f " Hi {value1}. Your Carbon Footprint is : {total}                pounds/year. You're carbon footprint is very high. You will have take up living green              practices " , font = ( " Times new roman " , 15 ) )

        label11.place ( x = 0 , y = 530 )


button1 = tk.Button ( root , text = " Submit " , command = subb )

button1.configure ( bg = " green " )

button1.place ( x = 0 , y = 490 )


root.mainloop()
