What actually was happening was that it was not able to get the value of radiobutton & hence printing a blank. Maybe you didn't notice it but if you print something else in that method,you would have noticed
Since I couldn't use fridgePK.item_recognition(item)
. I took test vales for them. Tell me if this works:
from Tkinter import *
def add_item():
def create_rec(item):
def saveREC():
print "hola"#for test purpose
print typeSel.get()
label2=Label(add_win, text="select item type:").pack()
#radio buttons creation
typeSel = StringVar()
R1 = Radiobutton(add_win, text="meat", variable=typeSel, value="meat")
R1.pack( anchor = W)
typeSel.set('meat')
saveBttn=Button(add_win, text="recognize this item in the future", command=saveREC).pack()
def saveEntry():
item=entry.get()
a=False
typeVar="hello"
if a==True:
print item, " is saved to ", typeVar
#if item isn't recognized then user can add item to recognition list
if a==False:
create_rec(item)
add_win=Tk()
entry=Entry(add_win, width=30)
entry.pack()
entry.focus_set()
saveBttn=Button(add_win, text="add item", width=25, command=saveEntry)
saveBttn.pack()
add_win.mainloop()
add_item()
