Create a GUI to get Sunset and Sunrise time using Python.

Prerequisite: Tkinter module

In this article, we are going to write python scripts to get sunset and sunrise time and bind it with the GUI application. Before starting we need to understand suntime and geopy module

Modules Needed:

suntime module: This module will return the sunset and sunrise time calculation python library. Run this command in your terminal for installation.

pip install suntime

geopy module: This module locates the coordinates of addresses, cities, countries, and landmarks across the globe using third-party geocoders and other data sources. Nominatim is a geocoder that is used for OpenStreetMap data. Run this command in your terminal for installation.

pip install geopy

Approach:

• Import all the required modules.
• Get latitude and longitude with geopy.
• Get the Sunrise time with Sun(latitude, longitude).get_sunrise_time() method.
• Get the dusk time with Sun(latitude, longitude).get_sunset_time() method.

Below is the Implementation:

Python3

# import required modules
import datetime
from suntime import Sun
from geopy.geocoders import Nominatim

# Nominatim API to get latitude and longitude
geolocator = Nominatim(user_agent="geoapiExercises")

# input place
place = "delhi"
location = geolocator.geocode(place)

# latitude and longitude fetch
latitude = location.latitude
longitude = location.longitude
sun = Sun(latitude, longitude)

# date in your machine's local time zone
time_zone = datetime.date(2020, 9,13)
sun_rise = sun.get_local_sunrise_time(time_zone)
sun_dusk = sun.get_local_sunset_time(time_zone)

# display
print("Sun rise at : ", sun_rise.strftime('%H:%M'))
print("Dusk at : ",sun_dusk.strftime('%H:%M'))

Output:

Sun rise at :  06:05
Dusk at :  18:28

Binding with GUI application

Python3

# import modules
from tkinter import *
from geopy.geocoders import Nominatim
import datetime
from suntime import Sun

# user defined function
def sun():

    try:

        geolocator = Nominatim(user_agent="geoapiExercises")

        ladd1 = str(e.get())
        location1 = geolocator.geocode(ladd1)

        latitude = location1.latitude
        longitude = location1.longitude

        sun = Sun(latitude, longitude)

        time_zone = datetime.datetime.now()

        sun_rise = sun.get_local_sunrise_time(time_zone)
        sun_dusk = sun.get_local_sunset_time(time_zone)

        res_rise = sun_rise.strftime('%H:%M')
        res_dusk = sun_dusk.strftime('%H:%M')

        result1.set(res_rise)
        result2.set(res_dusk)

    except:
        result1.set("oops! something get wrong")

# object of tkinter
# and background set to light grey
master = Tk()
master.configure(bg='light grey')
master.title("Sun")

# Variable Classes in tkinter
result1 = StringVar();
result2 = StringVar();


# Creating label for each information
# name using widget Label
Label(master, text="Enter place : " ,
      bg = "light grey").grid(row=1, sticky=W)
Label(master, text="Sunrise :",
      bg = "light grey").grid(row=3, sticky=W)
Label(master, text="Dusk :",
      bg = "light grey").grid(row=4, sticky=W)

# Creating label for class variable
# name using widget Entry
Label(master, text="", textvariable=result1,
      bg = "light grey").grid(row=3,column=1, sticky=W)
Label(master, text="", textvariable=result2,
      bg = "light grey").grid(row=4,column=1, sticky=W)


e = Entry(master,width = 50)
e.grid(row=1, column=1)


# creating a button using the widget
b = Button(master, text="Check",
           command=sun, bg = "white")
b.grid(row=1, column=2,columnspan=2,
       rowspan=2,padx=5, pady=5,)

mainloop()

Output:
