How to display a dataframe in tkinter - python-3.x

Question

I am new to Python and even newer to tkinter.
I've utilised code from stackoverflow (Switch between two frames in tkinter) to produce a program where new frames are called and placed on top of each other depending on what options the user selects. A stripped down version of my code is below. There are a lot more frames.
import tkinter as tk
from tkinter import font as tkfont
import pandas as pd
class My_GUI(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)
self.title_font = tkfont.Font(family='Helvetica', size=18, weight="bold", slant="italic")
container = tk.Frame(self)
container.pack(side="top", fill="both", expand=True)
container.grid_rowconfigure(0, weight=1)
container.grid_columnconfigure(0, weight=1)
self.frames = {}
for F in (StartPage, Page_2):
page_name = F.__name__
frame = F(parent=container, controller=self)
self.frames[page_name] = frame
frame.grid(row=0, column=0, sticky="nsew")
self.show_frame("StartPage")
def show_frame(self, page_name):
'''Show a frame for the given page name'''
frame = self.frames[page_name]
frame.tkraise()
class StartPage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
label = tk.Label(self, text="Welcome to....", font=controller.title_font)
label.pack(side="top", fill="x", pady=10)
button1 = tk.Button(self, text="Option selected",
command=lambda: controller.show_frame("Page_2"))
button1.pack()
class Page_2(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
label = tk.Label(self, text="The payment options are displayed below", font=controller.title_font)
label.pack(side="top", fill="x", pady=10)
#I want the able to be display the dataframe here
button = tk.Button(self, text="Restart",
command=lambda: controller.show_frame("StartPage"))
button.pack()
a = {'Option_1':[150,82.50,150,157.50,78.75],
'Option2':[245,134.75,245,257.25,128.63]}
df = pd.DataFrame(a,index=['a',
'b',
'c',
'd',
'e'])
print(df.iloc[:6,1:2])
if __name__ == "__main__":
app = My_GUI()
app.mainloop()
When Page_2 appears I want it to display a dataframe with the code below.
a = {'Option_1':[150,82.50,150,157.50,78.75],
'Option2':[245,134.75,245,257.25,128.63]}
df = pd.DataFrame(a,index=['a',
'b',
'c',
'd',
'e'])
print(df.iloc[:6,1:2])
I've searched SO e.g. How to display a pandas dataframe in a tkinter window (tk frame to be precise) (no answer provided) and other websites for an answer to similar question but without success.
How and where would I place my dataframe code selection to appear in the area I want when I select Page_2?

Check out pandastable.
It is quite a fancy library for displaying and working with pandas tables.
Here is a code example from their documentation:
from tkinter import *
from pandastable import Table, TableModel
class TestApp(Frame):
"""Basic test frame for the table"""
def __init__(self, parent=None):
self.parent = parent
Frame.__init__(self)
self.main = self.master
self.main.geometry('600x400+200+100')
self.main.title('Table app')
f = Frame(self.main)
f.pack(fill=BOTH,expand=1)
df = TableModel.getSampleData()
self.table = pt = Table(f, dataframe=df,
showtoolbar=True, showstatusbar=True)
pt.show()
return
app = TestApp()
#launch the app
app.mainloop()
and here a screenshot (also from their docs):

As a start, you could have a look at Label and Text widgets, that usually are used to display text in your GUI.
You could probably try something like:
class Page_2(tk.Frame):
def __init__(self, parent, controller):
# ... your code ...
global df # quick and dirty way to access `df`, think about making it an attribute or creating a function that returns it
text = tk.Text(self)
text.insert(tk.END, str(df.iloc[:6,1:2]))
text.pack()
# lbl = tk.Label(self, text=str(df.iloc[:6,1:2])) # other option
# lbl.pack() #
In the end, it really boils down to how fancy you want to be: the widgets are highly customizable, so you could achieve something very pleasing to the eye instead of the basic look of this example.
Edit:
I added a Combobox widget to select the option to display and a Button that prints it to the "display" widget of your choice.
from tkinter import ttk # necessary for the Combobox widget
# ... your code ...
class Page_2(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
label = tk.Label(self, text="The payment options are displayed below", font=controller.title_font)
label.pack(side="top", fill="x", pady=10)
global df
tk.Label(self, text='Select option:').pack()
self.options = ttk.Combobox(self, values=list(df.columns))
self.options.pack()
tk.Button(self, text='Show option', command=self.show_option).pack()
self.text = tk.Text(self)
self.text.pack()
tk.Button(self, text="Restart",
command=lambda: controller.show_frame("StartPage")).pack()
def show_option(self):
identifier = self.options.get() # get option
self.text.delete(1.0, tk.END) # empty widget to print new text
self.text.insert(tk.END, str(df[identifier]))
The text that is displayed is the default string representation of a data-frame's column; a custom text is left as an exercise.
