Prerequisite: Tkinter
In this article, we are going to write a python script to get the distance between two places and bind it with the GUI application. To install the GeoPy module, run the following command in your terminal.
pip install geopy
Approach used:
- Import the geopy module.
- Initialize Nominatim API to get location from the input string.
- Get latitude and longitude with geocoding ().
- Get the distance with distance() method in geopy.
The GUI would look like below:
Below is the Implementation:
Python3
# import modulefrom geopy.geocoders import Nominatimfrom geopy import distance# initialize Nominatim APIgeolocator = Nominatim(user_agent="geoapiExercises")# place inputInput_place1 = "delhi"Input_place2 = "patna"# Get location of the input stringsplace1 = geolocator.geocode(Input_place1)place2 = geolocator.geocode(Input_place2)# Get latitude and longitudeLoc1_lat, Loc1_lon = (place1.latitude), (place1.longitude)Loc2_lat, Loc2_lon = (place2.latitude), (place2.longitude)location1 = (Loc1_lat, Loc1_lon)location2 = (Loc2_lat, Loc2_lon)# display the distanceprint(distance.distance(location1, location2).km, " kms") |
Output:
852.5518024607962 kms
GUI Application to Measure Distance with Tkinter:
Python3
# import modulesfrom tkinter import *from geopy.geocoders import Nominatimfrom geopy import distance# user defined functiondef get_dis(): try: geolocator = Nominatim(user_agent="geoapiExercises") place1 = geolocator.geocode(str(e1.get())) place2 = geolocator.geocode(str(e2.get())) Loc1_lat,Loc1_lon = (place1.latitude),(place1.longitude) Loc2_lat,Loc2_lon = (place2.latitude),(place2.longitude) location1=(Loc1_lat,Loc1_lon) location2=(Loc2_lat,Loc2_lon) res = (str(distance.distance(location1, location2).km)+" Km") result.set(res) except: result.set("something went wrong")# object of tkinter# with background set to light greymaster = Tk()master.configure(bg='light grey')master.title("Find Distance")# Variable Classes in tkinterresult = StringVar();# Creating label for each information# name using widget Label Label(master, text="Enter first place : " , bg = "light grey").grid(row=1, sticky=W)Label(master, text="Enter second place : " , bg = "light grey").grid(row=2, sticky=W)Label(master, text="Result :", bg = "light grey").grid(row=3, sticky=W)# Creating label for class variable# name using widget EntryLabel(master, text="", textvariable=result,bg = "light grey").grid(row=3,column=1, sticky=W)e1 = Entry(master,width = 50)e1.grid(row=1, column=1)e2 = Entry(master,width = 50)e2.grid(row=2, column=1)# creating a button using the widget b = Button(master, text="Check", command=get_dis, bg = "white")b.grid(row=1, column=2,columnspan=2, rowspan=2,padx=5, pady=5,)mainloop() |
Output:
