python着色点代码
时间: 2023-02-08 09:53:26 浏览: 170
下面是一个简单的 Python 代码示例,使用 Matplotlib 绘制一个带有点的散点图并对点进行着色:
```
import matplotlib.pyplot as plt
x = [1, 2, 3, 4, 5]
y = [2, 4, 6, 8, 10]
colors = ['red', 'green', 'blue', 'purple', 'yellow']
plt.scatter(x, y, c=colors)
plt.show()
```
上面的代码使用 Matplotlib 绘制了一个带有 5 个点的散点图。点的横坐标和纵坐标分别为 x 和 y 列表,而点的颜色则由 colors 列表提供。'c'是 color 的缩写 可以用来表示颜色
使用scatter 这个函数可以绘制散点图,可以用来绘制点图
请注意,在运行此代码之前,需要确保已经安装了 Matplotlib 库。

生成python地图着色问题代码
Sure, I can help you with that. Here's an example code for generating a colored map in Python using the Matplotlib library:
```python
import numpy as np
import matplotlib.pyplot as plt
# Define the data
values = np.random.rand(10, 10)
# Define the colormap
cmap = plt.get_cmap('Greens')
# Plot the data with the colormap
plt.imshow(values, cmap=cmap)
# Show the plot
plt.show()
```
This code creates a random 10x10 array of values and uses the 'Greens' colormap to plot it as a colored map. You can modify the size of the array and use a different colormap to fit your specific needs. Let me know if you need further assistance.
python七巧板拼图代码
Python七巧板拼图代码可以使用turtle库来实现。以下是一个简单的示例代码:
```python
import turtle
# 创建一个画布和画笔
canvas = turtle.Screen()
pen = turtle.Turtle()
# 设置画笔的速度和颜色
pen.speed(3)
pen.color("black")
# 定义七巧板的形状和颜色
shapes = [
[(0, 0), (0, -100), (100, -100), (100, 0)],
[(0, 0), (0, -200), (100, -200), (100, -100)],
[(0, 0), (0, -100), (100, -100), (50, 0)],
[(0, 0), (0, -100), (50, -100), (50, 0)],
[(0, 0), (0, -50), (100, -50), (100, 0)],
[(0, 0), (0, -50), (50, -50), (50, 0)],
[(0, 0), (0, -150), (50, -150), (50, -100)]
]
colors = ["red", "orange", "yellow", "green", "blue", "indigo", "violet"]
# 绘制七巧板
def draw_puzzle():
for i in range(len(shapes)):
pen.penup()
pen.goto(shapes[i][0])
pen.pendown()
pen.fillcolor(colors[i])
pen.begin_fill()
for j in range(4):
pen.goto(shapes[i][j])
pen.end_fill()
# 调用绘制函数
draw_puzzle()
# 隐藏画笔
pen.hideturtle()
# 关闭画布
canvas.exitonclick()
```
这段代码使用turtle库创建了一个画布和画笔,然后定义了七巧板的形状和颜色。通过循环绘制七巧板,并使用填充颜色进行着色。最后隐藏画笔并关闭画布。
