您可能可以通过替换sys.stdout为自己的写入文本小部件的类似文件的对象来解决此问题。
例如：
import Tkinter as tk
import sys
class ExampleApp(tk.Tk):
def __init__(self):
tk.Tk.__init__(self)
toolbar = tk.Frame(self)
toolbar.pack(side="top", fill="x")
b1 = tk.Button(self, text="print to stdout", command=self.print_stdout)
b2 = tk.Button(self, text="print to stderr", command=self.print_stderr)
b1.pack(in_=toolbar, side="left")
b2.pack(in_=toolbar, side="left")
self.text = tk.Text(self, wrap="word")
self.text.pack(side="top", fill="both", expand=True)
self.text.tag_configure("stderr", foreground="#b22222")
sys.stdout = TextRedirector(self.text, "stdout")
sys.stderr = TextRedirector(self.text, "stderr")
def print_stdout(self):
'''Illustrate that using 'print' writes to stdout'''
print "this is stdout"
def print_stderr(self):
'''Illustrate that we can write directly to stderr'''
sys.stderr.write("this is stderr\n")
class TextRedirector(object):
def __init__(self, widget, tag="stdout"):
self.widget = widget
self.tag = tag
def write(self, str):
self.widget.configure(state="normal")
self.widget.insert("end", str, (self.tag,))
self.widget.configure(state="disabled")
app = ExampleApp()
app.mainloop()
