Python Forum

Hello. I'm new to Python and just started using Tkinter. I'm trying to use a calendar widget and I found this code from google search. The code works fine on my work computer but for some reason, it doesn't work on my home computer. Below is the code and I have attached a pic of the output screen. Any help would be appreciated.

try:
    import tkinter as tk
    from tkinter import ttk
except ImportError:
    import Tkinter as tk
    import ttk

from tkcalendar import Calendar, DateEntry

def example1():
    def print_sel():
        print(cal.selection_get())

    top = tk.Toplevel(root)

    cal = Calendar(top,
                   font="Arial 14", selectmode='day',
                   cursor="hand1", year=2018, month=2, day=5)
    cal.pack(fill="both", expand=True)
    ttk.Button(top, text="ok", command=print_sel).pack()

def example2():
    top = tk.Toplevel(root)

    ttk.Label(top, text='Choose date').pack(padx=10, pady=10)

    cal = DateEntry(top, width=12, background='darkblue',
                    foreground='white', borderwidth=2)
    cal.pack(padx=10, pady=10)

root = tk.Tk()
s = ttk.Style(root)
s.theme_use('clam')

ttk.Button(root, text='Calendar', command=example1).pack(padx=10, pady=10)
ttk.Button(root, text='DateEntry', command=example2).pack(padx=10, pady=10)

root.mainloop()

Did you do python3.8 -m pip install tkcalendar or which ever python version you're using?

I'm using Python 3.8 but I think that my work computer is Python 3.7

python3.8 is what I use

Could someone help me out with this problem? Thanks.
