Having trouble timing turtle movement

I wrote the following code, which creates expanding squares at two random locations. I would like to write a function f(squares, seconds) so that if the user inputs f(5,10), a new square would begin forming every 10 seconds, until 5 had formed.

I can't seem to find anything which lets me start a new square while one is still forming. I can either make two form at the same time, as in the code below, or have one be completed, and then for another to start forming. Help?

import sys
sys.setExecutionLimit(1000000)
import turtle
import random
wn = turtle.Screen()
#Creates alex the turtle
alex = turtle.Turtle()
alex.color('blue')
alex.pensize(3)
alex.ht()
alex.penup()
#creates bob the turtle
bob = turtle.Turtle()
bob.color('blue')
bob.pensize(3)
bob.ht()
bob.penup()

#Sets variables so that alex starts in a random location
a=random.randrange(360)
b=random.randrange(360)
x=random.randrange(50,150)
y=random.randrange(50,150)
#Sets variables so that bob starts in a random location
l=random.randrange(360)
m=random.randrange(360)
n=random.randrange(50,150)
o=random.randrange(50,150)
#Moves alex to his random starting location
alex.speed(100)
alex.left(a)
alex.forward(x)
alex.left(b)
alex.forward(y)
alex.pendown()
#Moves bob to his random starting location
bob.speed(100)
bob.left(l)
bob.forward(n)
bob.left(m)
bob.forward(o)
bob.pendown()

#Draws the 2 squares
for i in range(1,500):
    alex.forward(i)
    alex.left(90)
    bob.forward(i)
    bob.left(90)

The functionality you want requires independent execution threads. You need to work with the multi-threading package and tutorial

You will want logic such as this:

import time
import threading

def draw_square():
    # Draw a square in a random place
    length = random.randrange(360)
    width  = random.randrange(360)
    x_pos  = random.randrange(50,150)
    y_pos  = random.randrange(50,150)

    # Continue with your square-drawing logic;
    # you already know how to do this.

while True:
    threading.thread(draw_square)
    time.sleep(10)
