### Python Turtle 实现复杂烟花效果为了实现更加复杂的烟花效果，可以在基础版本上增加更多特性，比如多层爆炸、渐变色彩以及随机化参数等。下面是一个增强版的例子： ```python import turtle import random from math import sin, cos, radians def setup_screen(): screen = turtle.Screen() screen.bgcolor('black') screen.title("Complex Fireworks Show") def draw_firework(x, y): t = turtle.Turtle() t.hideturtle() t.speed(0) # Randomly choose a color and set up the initial position. colors = ['red', 'orange', 'yellow', 'green', 'blue', 'purple'] chosen_color = random.choice(colors) t.penup() t.goto(x, y) t.pendown() # Draw multiple layers of explosion with varying sizes and angles. for layer in range(3): # Three layers for complexity. angle_step = 360 / (random.randint(12, 24)) # Varying number of petals per layer. size_factor = (layer + 1) * 2 for degree in range(int(360/angle_step)): radian_angle = radians(degree * angle_step) if layer % 2 == 0: current_color = chosen_color else: other_colors = list(set(colors)-set([chosen_color])) current_color = random.choice(other_colors) t.color(current_color) t.setheading(radian_angle*180/pi) t.forward(size_factor * 50*sin(radian_angle)) t.backward(size_factor * 50*cos(radian_angle)) t.clear() # Clear previous layer before drawing next one. def main(): setup_screen() fireworks_count = 7 for _ in range(fireworks_count): x_pos = random.uniform(-300, 300) y_pos = random.uniform(-200, 200) draw_firework(x_pos, y_pos) if __name__ == '__main__': main() ``` 此代码通过引入额外的循环和条件语句来构建多层次的烟花图案，并且每一层都具有不同的角度分布和颜色变化[^1]。
