v0.config(bg="mintcream")
v0.geometry("400x300")
v0.title("INFORMATION")
label1=Label(v0, text="INFORMATION",font=("Arial", 18,"bold"), fg= "black", bg="mint cream", anchor=W, justify="center").pack()

while i <= 1000:
archivo = open('DATA BASE.txt', 'a')
archivo.write(ser.readline())
archivo.close()
i= i+1
ser.close()
