How to display content of Pandas data frame in Tkinter GUI window
提问by frenchfry
I managed to create a Pandas data frame with content I managed to create a simple window with TKinter.
我设法创建了一个包含内容的 Pandas 数据框，我设法使用 TKinter 创建了一个简单的窗口。
Pandas data frame content prints/displays fine in console or iPython but I would like to have what I see there to appear in my Tkinter window instead. Is there an easy way to achieve this?
Pandas 数据框内容可以在控制台或 iPython 中正常打印/显示，但我希望在那里看到的内容出现在我的 Tkinter 窗口中。有没有简单的方法来实现这一目标？

Here is an example for other Noobs who might have the same question one day. Sorry, can't explain how it works. Somewhere I found this example using that class "PrintToT1" and it seems to do what I wanted.
以下是其他有一天可能会遇到相同问题的新手的示例。抱歉，无法解释它是如何工作的。在某处我发现这个例子使用那个类“PrintToT1”，它似乎做我想做的。
import pandas as pd
import numpy as np
import sys
from tkinter import *
dates = pd.date_range('20160101', periods=6)
df = pd.DataFrame(np.random.randn(6,4),index=dates,columns=list('ABCD'))
root = Tk()
t1 = Text(root)
t1.pack()
class PrintToT1(object):
def write(self, s):
t1.insert(END, s)
sys.stdout = PrintToT1()
print ('Hello, world!')
print (df)
mainloop()
I would have posted the link to where I originally found this but after searching... and searching... and searching... trying... etc. I can not find it.
我会张贴链接到我最初找到它的地方，但在搜索...搜索...搜索...尝试...等等。我找不到它。
P.S. Credits goes to "Jarad" for finding and correcting the missing "dates" definition.
PS Credits 转到“Jarad”以查找和更正缺失的“日期”定义。
