python中turtle怎样用数字设置画笔颜色_笔记：turtle 库

在 Python 中使用 turtle 库，可以通过以下代码设置画笔的颜色：

import turtle

# 设置画笔颜色为红色
turtle.pencolor("red")

# 设置画笔颜色为 RGB 值为 (0, 0, 255) 的蓝色
turtle.pencolor(0, 0, 255)

# 设置画笔颜色为十六进制颜色码为 #00FF00 的绿色
turtle.pencolor("#00FF00")

其中，`pencolor()` 方法可以接收字符串、元组或十六进制颜色码作为参数来设置画笔颜色。如果传递的是字符串，则 turtle 库会尝试将其解析为颜色名称（如 "red"、"blue" 等）或十六进制颜色码（如 "#FF0000"、"#0000FF" 等）；如果传递的是元组，则应该是一个长度为 3 的 RGB 元组，分别表示红、绿、蓝三个颜色通道的值，取值范围为 0-255。
