local variables outside a function in python

Question

i have a code that goes like this

def inputs():
    q_number = int(1)
    number_of_q = int(0)
    q = {}
    x = {}
    y = {}
    xxxx = 1
    for i in range(4):
        C = float(qq[xxxx].get())
        X = float(xxx[xxxx].get())
        Y = float(yy[xxxx].get())
        if C != 0 or C != "":
            q[q_number] = C
            x[q_number] = X
            y[q_number] = Y
            q_number += 1
            number_of_q += 1

it works fine the only problem i have is i am trying to print the duples q , x , y outside of the function so i can use them in other stuff but it just wont work

i have tried to write the functiona as normal and global the duple q x y outside of the function

def inputs():
    q_number = int(1)
    number_of_q = int(0)
    q = {}
    x = {}
    y = {}
    xxxx = 1
    for i in range(4):
        C = float(qq[xxxx].get())
        X = float(xxx[xxxx].get())
        Y = float(yy[xxxx].get())
        if C != 0 or C != "":
            q[q_number] = C
            x[q_number] = X
            y[q_number] = Y
            q_number += 1
            number_of_q += 1
    global number_of_q, q_number, q, x, y
    print(number_of_q, q_number, q, x, y)

but the program gives me an error ( NameError: name 'number_of_q' is not defined ) can someone help me out ?

The below creates groups of StringVar. The update_fltdb function mirrors the StringVar groups to fltdb as float values. I fleshed it out with the 12 Entry widgets, and the Button.

import tkinter as tk

root  = tk.Tk()

SVDB  = ([], [], []) #groups of StringVar
fltdb = ([], [], []) #groups of float


#mirror SVDB as float results
def update_fltdb() -> None:
    fltdb = ([], [], [])
    for group, out in zip(SVDB, fltdb):
        for sv in group:
            try   : out.append(float(sv.get()))
            except: 
                sv.set('0.0')
                out.append(0.0)
    
    print(fltdb)
    

#build stringvar database
for x, group in enumerate(SVDB):
    for y in range(4):
        (sv := tk.StringVar(root)).set(f'{x}.{y}')
        tk.Entry(root, textvariable=sv).grid(column=x, row=y, sticky='nswe')
        group.append(sv)


#button
button = tk.Button(root, text='click', command=update_fltdb)
button.grid(column=x, row=y+1, sticky='e')
button.invoke() #update_fltdb


if __name__ == '__main__':
    root.mainloop()

You can unpack to any name(s) you need.

q, x, y    = fltdb
qv, xv, yv = SVDB
