Python Tkinter條目稍後存儲變量

Question

我對Tkinter很新穎，但是我怎樣才能得到我輸入的所有條目命令以作爲以後保存的變量？這是我的代碼，該條目存在。該程序旨在跟蹤進度，並使用整數，而不是浮點數。謝謝

然後它使用存儲的變量供將來用於其他組件，其中的作品。

name = Tk() 
    name.wm_title("Name") 

    Label(name, text="      First").grid(row=0, column=0) 
    Label(name, text="      Last").grid(row=0, column=2) 
    Label(name, text="    Starting height").grid(row=1, column=0) 
    Label(name, text="     Now height").grid(row=1, column=2) 
    Label(name, text="    Starting Age").grid(row=2, column=0) 
    Label(name, text="      Now Age").grid(row=2, column=2) 
    Label(name, text="  Starting Bench Press").grid(row=3, column=0) 
    Label(name, text=" Personal best Bench press").grid(row=3, column=2) 
    Label(name, text="  Starting Weighted Squat").grid(row=4, column=0) 
    Label(name, text="Personal best weighted squat").grid(row=4, column=2) 
    Label(name, text="   Starting deadlift").grid(row=5, column=0) 
    Label(name, text="  Personal best deadlift").grid(row=5, column=2) 
    Label(name, text="  Starting shoulder press").grid(row=6, column=0) 
    Label(name, text="Personal best shoulder press").grid(row=6, column=2) 
    Label(name, text="   Starting leg press").grid(row=7, column=0) 
    Label(name, text="  Personal best leg press").grid(row=7, column=2) 
    Label(name, text="  Starting lat pulldown").grid(row=8, column=0) 
    Label(name, text=" Personal best lat pulldown").grid(row=8, column=2)

    Now_age     = Entry(name) 
    Start_Bench_Press  = Entry(name) 
    Heaviest_Bench_Press  = Entry(name)

    Heaviest_Leg_Press  = Entry(name) 
    Start_Lat_Pulldown  = Entry(name) 
    Heaviest_Lat_Pulldown = Entry(name) 

    first.grid     (row=0, column=1) 
    last.grid     (row=0, column=3) 
    Starting_height.grid   (row=1, column=1)

    Heaviest_Lat_Pulldown.grid (row=8, column=3) 


    Button(name, text='Quit', command=name.destroy).grid(row=10, column=0, sticky=W, pady=4) 

    name.mainloop()

下面是使用IntVar保存從Entry插件的值的一個例子。

from tkinter import * 
from tkinter import messagebox 

name = Tk() 
name.wm_title("Name") 

Label(name, text="sFirst").grid(row=0, column=0) 

firstsv = IntVar() 
first = Entry(name, textvariable=firstsv) 

first.grid(row=0, column=1) 

b1 = Button(name, text='Show', command=lambda: messagebox.showinfo("hi", firstsv.get())) 
b1.grid(row=1, column=0, sticky=W, pady=4) 

name.mainloop() 

# use after loop 
print('firstsv = %d' % firstsv.get()) 

這是python 3的代碼。如果您使用的是Python 2（因爲許多初學者似乎還在做），它只是一個練習來轉換代碼。
