add entries and labels to the window tkinter - jacksfrustration - Oct-10-2023

Basically i want to build an app where the user can add entries and labels to the window
i have the following code

global cur_row,count
    cur_row+=1
    globals()[f'lbl{count}']=Label()
    globals()[f"lbl{count}"].grid(row=cur_row,column=0)
    globals()[f"ent{count}"]=Entry()
    globals()[f"ent{count}"].grid(row=cur_row,column=1)
    count+=1

the problem is the labels are not generated. All i get is the entry. I want a way to generate labels as well as entries. after that i need a way to retrieve all of the entry inputs and save them to a dictionary or csv file

What makes you think the labels are not created? You don't supply any label text, so how could you tell?

When creating tkinter widgets you should pass the parent widget as the first argument.

I don't think you want to add attributes to global. Make a list of entries and a function for creating an entry. Do the same for labels. Better yet. make a window class that has a dictionary of labels and a dictionary of entries.

import tkinter as tk


class Window(tk.Tk):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.label = {}
        self.entry = {}

    def add_label(self, text, id=None, row=None, col=0, **kwargs):
        """Add entry to window."""
        id = id or text
        if row is None:
            row = len(self.entry)
        self.label[id] = tk.Label(self, text=text, **kwargs)
        self.label[id].grid(row=row, column=col, padx=5, pady=5)
        return label[id]

    def add_entry(self, id, row=None, col=1, **kwargs):
        """Add entry to window."""
        if row is None:
            row = len(self.entry)
        self.entry[id] = tk.Entry(self, **kwargs)
        self.entry[id].grid(row=row, column=col, padx=5, pady=5)
        return entry[id]


def dump():
    for label, entry in zip(window.label, window.entry.values()):
        print(f"{label:10} {entry.get()}")


window = Window()
window.add_label("Row 1")
window.add_entry("Row 1")
window.add_label("Row 2")
window.add_entry("Row 2")
button = tk.Button(window, text="Press Me", command=dump)
button.grid(row=len(window.entry), column=0, columnspan=2, padx=5, pady=5)
window.mainloop()

Modifyng dict returned from globals() for sole purpose to dynamically create names is bad
Why you don't want to dynamically create variables
