使用 Python 构建一个 GUI 应用程序来获取两个地方之间的距离
原文:https://www . geeksforgeeks . org/build-a-GUI-application-to-get-two-place-distance-using-python/
先决条件:Tkit
在本文中，我们将编写一个 python 脚本来获取两个位置之间的距离，并将其与 GUI 应用程序绑定。要安装 GeoPy 模块，请在您的终端中运行以下命令。
pip 安装地质图
采用的方法:
- 导入地理模块。
- 初始化 Indigm API 以从输入字符串中获取位置。
- 通过地理编码获取纬度和经度()。
- 用地球物理学中的 distance()方法求距离。
图形用户界面如下所示:
下面是实现:
Python 3
# import module
from geopy.geocoders import Nominatim
from geopy import distance
# initialize Nominatim API
geolocator = Nominatim(user_agent="geoapiExercises")
# place input
Input_place1 = "delhi"
Input_place2 = "patna"
# Get location of the input strings
place1 = geolocator.geocode(Input_place1)
place2 = geolocator.geocode(Input_place2)
# Get latitude and longitude
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)
# display the distance
print(distance.distance(location1, location2).km, " kms")
输出:
852.5518024607962 kms
用 Tkit 测量距离的图形用户界面应用程序:
Python 3
# import modules
from tkinter import *
from geopy.geocoders import Nominatim
from geopy import distance
# user defined function
def 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 grey
master = Tk()
master.configure(bg='light grey')
master.title("Find Distance")
# Variable Classes in tkinter
result = 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 Entry
Label(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()
输出:
