python tkinter Entry widget Dynamic Name

Question

anyone can guide me of the following:

I want to dynamically create the Entry widget and assigned hierarchical name (i.e. e1, e2, e3...etc), so that in next step easily reference back to collect the information.

see my draft code below, its not working

bowList = pd.DataFrame(np.empty([12,2]),columns=[['F','S']])

main2 = tki.Tk()
main2.minsize(800,500)

mb1 = tki.Menu(main2)

fm = tki.Menubutton(mb1)

l1 = tki.Label(main2, text="Fore Name")
l1.place(x=50,y=5,width=70)

l2 = tki.Label(main2, text="Surname")
l2.place(x=300,y=5,width=70)

h=1
for i in np.arange(1,12):
    h = i * 30 
    tki.Label(main2, text=i).place(x=10,y=h,width=15)
    e1 = tki.StringVar(main2)
    e1 ="e1%i" %(i)
    e2 = "e2%i" %(i)
    print(e1), print(e2)
    e1 = tki.Entry(main2, width=25, textvariable=e1)
    e1.place(x=50,y=h)
    e1.insert(i,i)

    e2 = tki.Entry(main2, width=25)
    e2.place(x=250,y=h)


def BowSave():
    for i in np.arange(1,12):
           #bowList.iloc[i,0] = (e11.get())
           #bowList.iloc[i,1] = (e21.get())
           #np.where(i == 10, print(bowList))
           #print(main2.children.values())
           #print(e11.get())


b1 = tki.Button(main2, text="Save", command=BowSave, height=2, width=5)
b1.place(x=500,y=5)

print(main2.winfo_name)
main2.mainloop()

This snippet might get you started.

....

entry_text = ['e1', 'e2', 'e3']

....

    # add text entries
    for x, text in enumerate(entry_text):
        e = ttk.Entry(mFrame, width=80, name=text)
        e.grid(column=1, row=x, sticky='WE', padx=5, pady=5)
        e.insert(0, text)

....

    e1Text = master.children['mFrame'].children['e1'].get()
    e2Text = master.children['mFrame'].children['e2'].get()
