使用Python和matplotlib
```python
import numpy as np
import matplotlib.pyplot as plt
生成数据
t = np.linspace(0, 2 * np.pi, 1000)
x = 16 * np.sin(t)3
y = 13 * np.cos(t) - 5 * np.cos(2*t) - 2 * np.cos(3*t) - np.cos(4*t)
创建绘图
plt.figure(figsize=(8, 6))
plt.plot(x, y, color='red')
plt.fill(x, y, color='red', alpha=0.6)
plt.title('Python', fontsize=18)
plt.axis('equal')
plt.grid(True)
plt.show()
```
使用Python和turtle
```python
import turtle
设置屏幕
screen = turtle.Screen()
screen.title("爱心代码")
screen.bgcolor("white")
创建一个海龟对象
love = turtle.Turtle()
love.shape("turtle")
love.color("red")
love.speed(1)
开始绘制爱心
love.begin_fill()
love.left(140)
love.forward(224)
love.circle(-112, 200)
love.left(120)
love.circle(-112, 200)
love.forward(224)
love.end_fill()
隐藏海龟并显示窗口
love.hideturtle()
turtle.done()
```
使用C语言和printf
```c
include
int main() {
printf("\n\n\t\t ❤️ \n\n");
printf("\t ❤️ ❤️\n");
printf("\t n");
printf("\t ❤️ ❤️\n");
printf("\t ❤️\n");
return 0;
}
```
使用C语言和Tkinter
```python
import random
from math import sin, cos, pi, log
from tkinter import *
CANVAS_WIDTH = 640
CANVAS_HEIGHT = 480
CANVAS_CENTER_X = CANVAS_WIDTH / 2
CANVAS_CENTER_Y = CANVAS_HEIGHT / 2
IMAGE_ENLARGE = 11
HEART_COLOR = "FFC0CB"
def heart_function(t, shrink_rat):
return 16 * sin(t)3 * shrink_rat
root = Tk()
canvas = Canvas(root, width=CANVAS_WIDTH, height=CANVAS_HEIGHT)
canvas.pack()
x = CANVAS_CENTER_X
y = CANVAS_CENTER_Y
shrink_rat = 1
for i in range(100):
x_pos = heart_function(i * pi / 50, shrink_rat)
y_pos = heart_function(i * pi / 50, shrink_rat)
canvas.create_oval(x_pos - 5, y_pos - 5, x_pos + 5, y_pos + 5, fill=HEART_COLOR)
root.mainloop()
```
使用C语言和ASCII字符
```c
include
int main() {
int i, j;
for (i = 0; i < 5; i++) {
for (j = 0; j <= 2 * i; j++) {
if ((i % 2 == 0 && j % 4 == 0) || (i % 2 == 1 && j % 4 == 2)) {
printf("*");
} else {
printf(" ");
}
}
printf("\n");
}
for (i = 0; i < 5; i++) {
for (j = 0; j < i; j++) {
printf(" ");
}
for (j = 0; j < 2 * (5 - i); j++) {
printf("*");
}
printf("\n");
}
return 0;
}
```
这些示例展示了如何使用不同的编程语言和库来输出爱心图案。
