Getting all of the Entry text content from a frame

Question

If I had a Frame named as the variable table which has multiple Entry widgets within this Frame, would there be a way of getting all the Entry widgets' text content?

Answer 1

Yes. In the example below when the button is clicked every child in a parent widget is checked whether are equal or not to be an entry, then their contents are printed:

try:
    import tkinter as tk
except ImportError:
    import Tkinter as tk


def get_all_entry_widgets_text_content(parent_widget):
    children_widgets = parent_widget.winfo_children()
    for child_widget in children_widgets:
        if child_widget.winfo_class() == 'Entry':
            print(child_widget.get())


def main():
    root = tk.Tk()
    table = tk.Frame(root)
    for _ in range(3):
        tk.Entry(table).pack()
    tk.Button(table, text="Get",
        command=lambda w=table: get_all_entry_widgets_text_content(w)).pack()
    table.pack()
    tk.mainloop()


if __name__ == '__main__':
    main()

One could have a much better get_all_entry_widgets_text_content method based on how the entries are instantiated, however, this one should work for all direct children regardless.
