大学0编程基础却被布置了Python语言编程

完全没有学过编程，却让我们用Python做一个，完全不会啊，网络上的教程也看不懂

import turtle

x = 0
color = ["red", "green", "pink"]
for i in range(3):
    turtle.penup()
    turtle.goto(x, 0)
    turtle.pendown()
    turtle.begin_fill()
    turtle.color(color[i])
    turtle.circle(100, steps=3)
    turtle.hideturtle()
    turtle.end_fill()
    x += 200

import turtle


x = -100
color = ["red", "green", "pink", "blue"]
for i in range(4):
    turtle.penup()
    turtle.goto(x, 0)
    turtle.pendown()
    turtle.begin_fill()
    turtle.color(color[i])
    turtle.circle(100)
    turtle.hideturtle()
    turtle.end_fill()
    x += 200
