[Python] When creating a function using the turtle module, Python says my turtle name variable...

I am making a function draw_square that draws a square using turtle. It takes (t,side_length) where t is turtle name and side_length is the side length. However when testing in thonny using draw_square(dave,50) it says name 'dave' is not defined

Tried importing turtle before creating my function

import turtle
def draw_square(t, side_length):
"""Use the turtle t to draw a square with side_length."""

t=turtle.Turtle()
t.forward(side_length)
t.right(90)
t.forward(side_length)
t.right(90)
t.forward(side_length)
t.right(90)
t.forward(side_length)
t.right(90)


Expected result:

draws a square of predetermined length after giving turtle name and length.

Actual result:

"Traceback (most recent call last):
File "<pyshell>", line 1, in <module>
NameError: name 'dave' is not defined"
