在 tkinter 而不是控制台中定位输出

Question

我正在使用graphlab打印出建议，并让我的tkinter GUI当前在控制台中打印出建议结果，我不知道如何让它在GUI中打印。

类"UserID"是我有一个按钮的地方，它调用"printrec"函数，但只在控制台中打印出建议。

from Tkinter import *
import sqlite3


class Welcome():
     def __init__(self,master):

          self.master=master
          self.master.geometry('170x110+100+200')
          self.master.title('Welcome!')
          self.label1=Label(self.master,text='Music Recommender',fg='black', bg="red").grid(row=0,column=1)
          self.button1=Button(self.master,text="Enter UserID",fg='black', bg="blue", command=self.gotoUserID).grid(row=1,column=1)
          self.button2=Button(self.master,text="Comparing models",fg='black', bg="blue").grid(row=2,column=1)
          #self.button3=Button(self.master,text="Click to print recs",fg='red',command=self.rec).grid(row=3,column=1)
          self.button4=Button(self.master,text="Exit",fg='black' , bg="blue",command=self.exit).grid(row=4,column=1)


     def exit(self):
        #exit button#
          self.master.destroy()
     def gotoUserID(self):
        #USERID GUI#    
          root2=Toplevel(self.master)
          myGUI=UserID(root2)
class UserID():
    #userID class prints song recs 
     def __init__(self,master):

          self.userRec=int()
          self.master=master
          self.master.geometry('400x250+100+200')
          self.master.title('ID recommender')
          self.label2=Label(self.master,text='Welcome to the Music Recommender',fg='red').grid(row=0,column=0)
          self.label2=Label(self.master,text='Please enter UserID: ',fg='black').grid(row=3,column=0)
          self.ID=Entry(self.master,textvariable=self.userRec).grid(row=3,column=1)
          self.button4=Button(self.master,text="Get recommendations",fg='red',command=self.printrec).grid(row=7,column=0)
          self.button5=Button(self.master,text="Exit",fg='red',command=self.exit).grid(row=9,column=0)
     def printrec(self):
        #currently prints song recs in console
          print song_recommendations



def main():
    root=Tk()
    root.configure(background='blue')
    myGUIWelcome=Welcome(root)
    root.mainloop()
if __name__ == '__main__':
     main()

这是我用来推荐的模型。它使用graphlab包。

recs_model = gl.recommender.ranking_factorization_recommender.create(plays_df, user_id="userID", item_id="songID", target="plays")
recommendations = recs_model.recommend(users=["3a613180775197cd08c154abe4e3f67af238a632"])
song_recommendations = recommendations.join(songs_df, on="songID", how="inner").sort("rank")

这是我想出现在我的 GUI 中的输出，但我不确定是否可以将这样的框架打印到 tkinter 中。

你可以制作GUI：

from tkinter import *
root = Tk()
Console = Text(root)
Console.pack()
root.mainloop()

然后你可以重写打印函数：

def write(*message, end = "n", sep = " "):
    text = ""
    for item in message:
        text += "{}".format(item)
        text += sep
    text += end
    Console.insert(INSERT, text)

这里有 tkinter 中的输出，你只需要调用 write(( 而不是 print((
