Ответ:

Перед запуском скрипту буде потрібно встановити дві бібліотеки(через cmd - якщо ви запускаєте у Windows):

• ManagerTk, командою: pip install ManagerTk
• PIL, командою: pip install Pillow

Python:

import tkinter

import ManagerTk

window = tkinter.Tk()

window.geometry("500x250")

window.resizable(False,False)

def redirect_1t2_page():

 try:

     h_value, p_value, n_value, k_value = (float(entry_h.get()), float(entry_p.get()), float(entry_n.get()), float(entry_k.get()))

     if h_value < 0 or p_value < 0 or k_value < 0 or n_value < 0:

         raise ValueError

     height_water = h_value + p_value*n_value

     hours_past = 0

     water_level = h_value

     while water_level < k_value:

         hours_past += 1

         water_level += p_value

     result_res["text"] = f"Height water in lake past {n_value} hours: {height_water}cm."

     result_res_3_page["text"] = f"Water level has been {k_value} cm past: {hours_past} hours."

     error_title["text"] = ""    

     ManagerTk.redirect_pages(page_1, page_2)

 except:

     error_title["text"] = "Error!     Please, enter correct values."

 

def redirect_2t1_page():

 ManagerTk.redirect_pages(page_2, page_1)
