Removing 'Week Number' column in Calendar Widget in Python

The documentation is poor, you have to dig in the source code.

The weeks number column corresponds to a list of wlabel (instance of ttk.Label()) called _week_nbs. So you can loop over them and destroy them one after one:

for i in range(6):    cal._week_nbs[i].destroy()

Full program:

try:    import tkinter as tk    from tkinter import ttkexcept ImportError:    import Tkinter as tk    import ttkfrom tkcalendar import Calendar, DateEntrydef 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)    for i in range(6):       cal._week_nbs[i].destroy()    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()

Demo:

The following seems to work to turn the weeknumbers off:

self.de = DateEntry(self.frame, width=12, background='darkblue',                foreground='white',showweeknumbers=False,firstweekday='sunday')# To see other parameters that you can changeprint("DE keys=",self.de.keys())

Documentation for weeknumbers

Unfortunately, it doesn't come as an option. In the __init__ method of tkcalendar the week numbers are always added, no matter what the options are:

    ...    self._week_nbs = []    self._calendar = []    for i in range(1, 7):        self._cal_frame.rowconfigure(i, weight=1)        wlabel = ttk.Label(self._cal_frame, style='headers.%s.TLabel' % self._style_prefixe,                           font=self._font, padding=2,                           anchor="e", width=2)        self._week_nbs.append(wlabel)        wlabel.grid(row=i, column=0, sticky="esnw", padx=(0, 1))        self._calendar.append([])        for j in range(1, 8):            label = ttk.Label(self._cal_frame, style='normal.%s.TLabel' % self._style_prefixe,                              font=self._font, anchor="center")            self._calendar[-1].append(label)            label.grid(row=i, column=j, padx=(0, 1), pady=(0, 1), sticky="nsew")            if selectmode is "day":                label.bind("<1>", self._on_click)

You may want to try other widgets as suggested here, it seems like ttkcalendar wouldn't have week numbers.
