How to place an entry field next to label correctly using Python Tkinter?

Question

I have got a problem with spacing entry fields in window. It places not next to the label.

I tried to change numbers of rows and columns to place it right next to labels, bit it doesn't work. Now these fields just levitate.

Window

Here is my code:

from tkinter import *
from tkinter import ttk
import tkinter as tk
from tkinter import Tk


class Window(Tk):
    is_reset = True

    def __init__(self):
        super().__init__()
        self.geometry("720x465+760+200")
        self.resizable(True, True)
        self.title("Калькулятор СМО")
        self.icon = PhotoImage(file="smile.png")
        self.iconphoto(False, self.icon)

        self.notebook = ttk.Notebook()
        self.notebook.grid()

        self.frame1 = ttk.Frame(self.notebook)
        self.frame2 = ttk.Frame(self.notebook)
        self.frame3 = ttk.Frame(self.notebook)
        self.frame1.grid()
        self.frame2.grid()
        self.frame3.grid()
        self.notebook.add(self.frame1, text="Одноканальна СМО з відмовами")
        self.notebook.add(self.frame2, text="Багатоканальна СМО з відмовами")
        self.notebook.add(self.frame3, text="Одноканальна СМО з очікуванням з обмеженою чергою")


    def make_frame1(self):
        intensity_lambda_label = tk.Label(self.frame1, text="Введіть інтенсивність λ", font=("Helvetica", 14))
        intensity_lambda_label.grid(column=0, row=1)
        intensity_lambda_entry = ttk.Entry()
        intensity_lambda_entry.grid(column=1, row=1)
        intensity_miu_label = tk.Label(self.frame1, text="Введіть інтенсивність μ", font=("Helvetica", 14))
        intensity_miu_label.grid(column=0, row=2)
        intensity_miu_entry = ttk.Entry()
        intensity_miu_entry.grid(column=1, row=2)


    def run(self):
        self.make_frame1()
        self.mainloop()


if __name__ == '__main__':
    window = Window()
    window.run()

Because the tk.Labels are in frame1, when you .grid() them in the frame, it puts them in the frame. When you put the Entry in root, it .grid()s them in root.

You can fix it by moving the Entry into frame1 when you create them like so:

ttk.Entry(self.frame1)

All in all it would look like this:

        intensity_lambda_label = tk.Label(self.frame1, text="Введіть інтенсивність λ", font=("Helvetica", 14))
        intensity_lambda_label.grid(column=0, row=1)
        intensity_lambda_entry = ttk.Entry(self.frame1)
        intensity_lambda_entry.grid(column=1, row=1)
        intensity_miu_label = tk.Label(self.frame1, text="Введіть інтенсивність μ", font=("Helvetica", 14))
        intensity_miu_label.grid(column=0, row=2)
        intensity_miu_entry = ttk.Entry(self.frame1)
        intensity_miu_entry.grid(column=1, row=2)
