打印到Tkinter GUI，而不是控制檯

Question

我寫了一些包含少量函數的腳本來完成一些網頁掃描。運行腳本時，結果使用簡單的「打印」命令打印到IDLE shell。

我有一個基本的tkinter GUI，它會在單擊按鈕時運行腳本，但結果仍然會打印到shell。如何調整我的代碼，以便在調用Master.master（）時，嵌入在該進程中的所有打印語句都會打印到我的GUI上的某個區域。我的代碼如下：

from tkinter import * 
import Master #Importing my scraper function 

win = Tk() 
win.title('Hashtag Scraper') 

SearchButton = Button(win,text = 'Search') 

SearchButton.grid(row=2,column = 1) 

htag_label = Label(win,text = 'What Hashtag?') 
htag_label.grid(row = 1,column = 0) 

email_label = Label(win,text = 'FB Email') 
email_label.grid(row = 1,column = 1) 

password_label = Label(win,text = 'FB Password') 
password_label.grid(row = 1,column = 2) 

def button(): 
    htag = hashtag.get() 
    user = usr.get() 
    password = pwd.get() 
    Master.master(htag,refresh = 3,usr = user,pwd = password) #Function call - want this to print on GUI instead of shell 

#win.bind('<Return>', SearchButton) 

SearchButton.configure(command = button) 


hashtag = StringVar() 
#hashtag.set('Hashtag') 
hashtag_entry = Entry(win,textvariable=hashtag) 
hashtag_entry.grid(row = 0, column = 0) 

usr = StringVar() 
usr.set('test@aol.com') 
usr_entry = Entry(win,textvariable=usr) 
usr_entry.grid(row = 0, column = 1) 

pwd = StringVar() 
#pwd.set('FB Password') 
pwd_entry = Entry(win,textvariable=pwd) 
pwd_entry.grid(row = 0, column = 2)

根據您想要顯示master方法調用的結果對你的GUI和什麼樣的小部件的地方，或者是在新彈出的文本框窗口中提到的意見，將其更改爲一種小工具，你想使用：

class Master: 
    def __init__(self, htag, refresh, usr, pwd): 
     self.htag = htag 
     self.refresh = refresh 
     self.usr = usr 
     self.pwd = pwd 

    def master(self): 
     return '\n'.join([self.htag, str(self.refresh), self.usr, self.pwd]) 

...

def button(): 
    htag = hashtag.get() 
    user = usr.get() 
    password = pwd.get() 
    m = Master(htag, refresh = 3, usr = user, pwd = password) 
    master_response = m.master() #Function call - want this to print on GUI instead of shell 

    top = Toplevel() 
    top.title("Response from master method") 
    # response_message = "Search Button pushed response" 
    msg = Message(top, text=master_response) 
    msg.pack() 

    button = Button(top, text="Dismiss", command=top.destroy) 
    button.pack()
