Description : Entry widgets are the basic widgets of Tkinter used to get input, for example text strings, from the client of an application. This gadget permits the client to enter a solitary line of text. In the event that the client enters a string, which is longer than the accessible showcase space of the gadget, the substance will be looked over. This implies that the string can't be found completely. The bolt keys can be utilized to move to the imperceptible pieces of the string. In the event that you need to enter various lines of text, you need to utilize the content widget. A section gadget is likewise restricted to single text style. The linguistic structure of a section widget resembles this: w = Entry(master, alternative, ... ) "ace" speaks to the parent window, where the section gadget ought to be put. Like different widgets, it's conceivable to additional impact the delivering of the widget by utilizing alternatives. The comma isolated rundown of choices can be unfilled.Code : import tkinter as tk master = tk.Tk()tk.Label(master, text="Selling Price").grid(row=0)tk.Label(master, text="Purchase Price").grid(row=1) e1 = tk.Entry(master)e2 = tk.Entry(master) e1.grid(row=0, column=1)e2.grid(row=1, column=1) fields = ('Selling Price', 'Purchase Price', 'MarkUp', 'Percentage MarkUp', 'Profit Margin') def MarkUp(entries): # Selling Price: s = (float(entries['Selling Price'].get()) print("s",s) # Purchase Price: p = float(entries['Purchase Price'].get()) print("p",p) markup = (s-p)/p entries['MarkUp'].delete(0, tk.END) entries['MarkUp'].insert(0, markup ) print("MarkUp: %f" % float(markup)) def Percentage MarkUp(entries): # Selling Price: s = (float(entries['Selling Price'].get()) print("s",s) # Purchase Price: p = float(entries['Purchase Price'].get()) print("p",p) markup = (s-p)/p p_markup = markup*100 entries['Percentage MarkUp'].delete(0, tk.END) entries['Percentage MarkUp'].insert(0, p_markup ) print("Percentage MarkUp: %f" % float(p_markup)) def Profit Margin(entries): # Selling Price: s = (float(entries['Selling Price'].get()) print("s",s) # Purchase Price: p = float(entries['Purchase Price'].get()) print("p",p) p_margin = (s-p)/s entries['Profit Margin'].delete(0, tk.END) entries['Profit Margin'].insert(0, p_margin ) print("Profit Margin: %f" % float(p_margin)) if __name__ == '__main__': root = tk.Tk() ents = makeform(root, fields) b1 = tk.Button(root, text='MarkUp', command=(lambda e=ents: markup(e))) b1 = tk.Button(root, text='Percentage MarkUp', command=(lambda e=ents: p_markup(e))) b1 = tk.Button(root, text='Profit Margin', command=(lambda e=ents: p_margin(e))) b1.pack(side=tk.CENTER, padx=5, pady=5)
