Adding Textfield in Tkinter - user-interface

Question

I want to programm a simple 'calculator'.. Some Input fields, then some calculations with those inputs in the background and then I want to see output.
In a simple form it looks like that:
a-e: are input fields.
f-h: output fields.
The calculations in the background and the showing of output goes well.
Now I want to have a line between e and f that says: Output
Without any entry field or sth.. just a textfield.
Can someone help me, how to insert a textfield on a specific place ?
This is the code:
fields = ('a', 'b', 'c', 'd', 'e',
'f (in EUR)', 'g (days per year)', 'h in %')
def initUI(self):
self.master.title("Calculator")
self.pack(fill=BOTH, expand=1)
Style().configure("TFrame", background="#111")
bardejov = ImageTk.PhotoImage(bard)
label1 = Label(self, image=bardejov)
label1.image = bardejov
label1.place(x=20, y=20)
def total_assets(entries):
# period rate:
a = (float(entries['a'].get()))
b = (float(entries['b'].get()))
c = (float(entries['c'].get()))
d = (float(entries['d'].get()))
e = (float(entries['e'].get()))
entries['f'].insert(0, calc1 )
entries['g'].insert(0, np.round( calc2 ) )
entries['h'].insert(0, calc3 )
#calc1,cal2,calc3 are some calculations with the input fields
def makeform(root, fields):
entries = {}
for field in fields:
print(field)
row = tk.Frame(root)
lab = tk.Label(row, width=50, text=field+": ", anchor='w')
ent = tk.Entry(row)
ent.insert(0, "0")
row.pack(side=tk.TOP,
fill=tk.X,
padx=5,
pady=5)
lab.pack(side=tk.LEFT)
ent.pack(side=tk.RIGHT,
expand=tk.YES,
fill=tk.X)
entries[field] = ent
ent.config(background="gray")
return entries
if __name__ == '__main__':
root = tk.Tk()
root.title("hello")
root.columnconfigure(1, weight=1)
#root.geometry("1000x300") #Width x Height
#root.grid_columnconfigure("50")
ents = makeform(root, fields)
b1 = tk.Button(root, text='do',
command=(lambda e=ents: total_assets(e)))
#ents.place(x=10, y=115, height=30, width=200)
b1.pack(side=tk.LEFT, padx=5, pady=5)
b2 = tk.Button(root, text = "reset",
command=(lambda e=ents: restart_program(e)))
b2.pack(side=tk.LEFT, padx=5, pady=5)
root.mainloop()

You can use below code to create a separator with text:
def create_separator(parent, text=None):
frame = tk.Frame(parent)
frame.columnconfigure(0, weight=1)
ttk.Separator(frame, orient=tk.HORIZONTAL).grid(row=0, column=0, sticky='ew')
if text:
tk.Label(frame, text=text).grid(row=0, column=0, padx=10, sticky='w')
return frame
Then inside the for loop of makeform():
for field in fields:
...
ent.config(background="gray")
if field == 'e':
# add a separator
sep = create_separator(root, 'Output')
sep.pack(side=tk.TOP, fill=tk.X, padx=5, pady=5)
