Tkinter Helper: autogenerate code for GUIs

Can we make an app that generate code to make graphic user interface fastly? I think we can. Let’s build it by ourselves. Tkinter, Python and the usual tools, in the following code with a little video explanation at the end.

The code

import tkinter as tk
import os

# WIDGETS STRINGS


entry_counter = 1
button_counter = 1
def entry_code():
    global entry_counter
    w_string = """
display1 = tk.StringVar()
entry1 = tk.Entry(root,
    relief=tk.FLAT,
    textvariable=display1,
    justify='right',
    bg='orange')
entry1.pack()
entry1["font"] = "arial 30 bold"
    """
    w_string2 = w_string.replace("display1", "display" + str(entry_counter))
    w_string2 = w_string2.replace("entry1", "entry" +  str(entry_counter))
    text.insert(tk.END, w_string2)
    entry_counter += 1
    place_mainloop()

def button_code():
    global button_counter
    w_string = """

            #relief=tk.FLAT,

            #command=None,
            #image=tk.PhotoImage("img.png")

"""
    w_string2 = w_string.replace("b1", "b" + str(button_counter))
    text.insert(tk.END, w_string2)

        rep = text.get("0.0", tk.END)
        rep = rep.replace("root.mainloop()", "")
        text.delete("0.0", tk.END)
        text.insert("0.0", rep)
        text.insert(tk.END, "root.mainloop()")

def save_code():
    if "root.mainloop()" not in text.get("0.0", tk.END):
        text.insert(tk.END, "root.mainloop()")
    with open("project.py", "w") as file:
        file.write(text.get("0.0", tk.END))
    os.startfile("project.py")

frame1.pack(side="left")

    # BUTTON TO CREATE ONE OR MORE ENTRIES
    b1 = tk.Button(frame1, text="entry", command=entry_code)
    b1.pack()

    # BUTTON TO CREATE ONE OR MORE BUTTONS

    b2.pack()

    # BUTTON THAT SHOWS THE WINDOW WITH THE WIDGETS
    b3 = tk.Button(frame1, text="save", command=save_code)
    b3.pack()

menu()
