需要使用 Tkinter 和 Python 为 km 或 mi 创建选项

Question

下面我找到并修改了一段代码，用于计算两个位置之间的距离。我正在为简单的用户输入创建一个 GUI。一切都按预期工作，但如果我能完成两件事，那就更好了。

有一个切换或选择可以让我以公里或米显示距离
有什么方法可以使输出四舍五入，使其小数点后没有那么多数字吗？

我假设它必须是基于对象选择的某种类型的变量？

# import modules 
from tkinter import *
from geopy.geocoders import Nominatim 
from geopy import distance 

# user defined funtion 
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).mi)+" Mi") 

      result.set(res) 
  except: 
      result.set("someting 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="Start Location : " , bg = "light grey").grid(row=1, sticky=W) 
Label(master, text="End Location : " , 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()

Answer 1

首先在结果行前添加两个单选按钮：

Label(master, text="Unit :", bg="light gray").grid(row=3, sticky=W)
Label(master, text="Result :", bg = "light grey").grid(row=4, sticky=W) # changed to row 4
...
f1 = Frame(master)
f1.grid(row=3, column=1, sticky=W)
unit = StringVar(value="mi")
Radiobutton(f1, text="miles", value="mi", variable=unit, bg="light gray").pack(side="left")
Radiobutton(f1, text="km", value="km", variable=unit, bg="light gray").pack(side="left")

result = StringVar(); 
Label(master, text="", textvariable=result,bg = "light grey").grid(row=4,column=1, sticky=W) # changed to row 4

然后根据里面选择的单位调用相应的函数get_dis():

def get_dis():
    try:
        ...
        if unit.get() == 'mi':
            res = str(round(distance.distance(location1, location2).mi, 3))+" Mi"
        else:
            res = str(round(distance.distance(location1, location2).km, 3))+" km"
    ...

注意round(..., 3)用于将结果四舍五入为小数点后3位。

Answer 2

因为我们已经通过 check 按钮获得了其中一个单位的距离..让我们使用它。我们会将它的结果转换为另一个。将 Check 更改为 Distance in miles，为 KM 添加了一个新按钮。创建一个将英里转换为公里的函数。然后一个函数来调用这两个函数。Two。这将获得以英里为单位的距离（get_dis）并转换为公里（km_mi）。结果将没有小数。我用了int。如果您想要小数，可以按照其他答案中的建议使用 round。
