Retrieving Data from Tkinter Window

You can use list or dictionary to store the variables. Below is an example using dictionary:

variables = {}while number != (max+1):    subject = f"Subject {number}"    Subject1_Label = Label(master, text=subject)    Subject1_Label.grid(row=number, column=0, pady=6)    Subject1 = All_Subjects.get(number)    variable = StringVar(master)    variable.set(Subject1[0])    variables[subject] = variable  # save the variable    w = OptionMenu(master, variable, *Subject1)    w.grid(row=number, column=1, pady=6)    subject_amount = subject_amount + 1    number = number + 1

Then you can use something like variables["Subject 1"].get() to get the selected item of "Subject 1".

Update with an example:

from tkinter import *# just for providing "All_Subjects.get(number)" in the while loopclass All_Subjects:    subjects = ("math stand", "english standard", "chem", "timber", "child studies")    def get(n):        return All_Subjects.subjectsmaster = Tk()max = 5variables = {}number = 1subject_amount = 0while number != (max+1):    subject = f"Subject {number}"    Subject1_Label = Label(master, text=subject)    Subject1_Label.grid(row=number, column=0, pady=6)    Subject1 = All_Subjects.get(number)    variable = StringVar(master)    variable.set(Subject1[0])    variables[subject] = variable  # save the variable    w = OptionMenu(master, variable, *Subject1)    w.grid(row=number, column=1, pady=6)    subject_amount = subject_amount + 1    number = number + 1def show_subjects():    # use "Subject X" as key to get the selected subjects     for i in range(1, max+1):        subject = f"Subject {i}"        print(f"{subject}: {variables[subject].get()}")    # or simply    #print([var.get() for var in variables.values()])Button(master, text="Next", command=show_subjects).grid(column=2, padx=10, pady=10)master.mainloop()
