处理:有没有办法把我的形状放到一个循环中，让我的代码变得更短？

shapes = ['circle', 'square', 'triangle']

for shape in shapes:
    print(f"Processing {shape}")
    # 这里可以添加具体的形状处理代码

shapes = ['circle', 'square', 'triangle']
index = 0

while index < len(shapes):
    print(f"Processing {shapes[index]}")
    # 这里可以添加具体的形状处理代码
    index += 1

def process_shapes(shapes, index=0):
    if index >= len(shapes):
        return
    print(f"Processing {shapes[index]}")
    # 这里可以添加具体的形状处理代码
    process_shapes(shapes, index + 1)

shapes = ['circle', 'square', 'triangle']
process_shapes(shapes)

# 错误的循环条件
while True:
    print("This will run forever!")

# 正确的循环条件
count = 0
while count < 10:
    print(f"Iteration {count}")
    count += 1

results = []

for i in range(5):
    results.append(i * 2)

print(results)  # 输出: [0, 2, 4, 6, 8]
