前言

你用勤劳敲打创意的键盘，你用智慧编辑巧妙的方案，你用坚持创造神奇的页面，你用勇气开发网络的资源，你就是多才可爱的程序媛。
在这个特殊的日子里，我停止了刷题，写下这篇文章，为「IT女神勋章」而战。

一、IT女神勋章

本篇就通过不同的语言来为女神绘制❤️。

二、绘制爱心

C知道：帮我使用python画一个爱心

代码

对回答的代码进行简单调整如下：

import turtle
# 设置画布大小和背景颜色
turtle.setup(width=700, height=700)
turtle.bgcolor("white")
# 定义画爱心的函数
def draw_heart():
    turtle.color('Pink')  # 设置画笔颜色
    turtle.begin_fill()  # 开始填充
    turtle.left(45)  # 向左旋转45度
    turtle.forward(200)  # 向前走200步
    turtle.circle(100, 180)  # 画半圆
    turtle.right(90)  # 向右旋转90度
    turtle.circle(100, 180)  # 画半圆
    turtle.forward(200)  # 向前走200步
    turtle.end_fill()  # 结束填充
# 调用画爱心的函数
draw_heart()
# 隐藏画笔
turtle.hideturtle()
# 显示画布
turtle.done()
