如何从Python列表提取坐标值用于CAD软件输入？

给定列表：

some_list=["PointID:","1","'Y':", "1.134","'X':","1.223", "'Z':","1.0","PointID","2", "'Y':","1.4", "'X':","1.75","'Z':","1.0"]

需要提取其中的坐标值（如1.134、1.223等），保存为TXT文件作为CAD绘图输入，期望输出格式：

Y: 1.134 
X: 1.223 

尝试过以下代码，但无法获取坐标值：

some_list=["PointID:","1","'Y':", "1.134","'X':","1.2223", "'Z':","1.0","PointID","2", "'Y':","1.4", "'X':","1.75","'Z':","1.0"]
for index, element in enumerate(some_list): 
    if element == "'X':" or element == "'Y':" or element == "'Z':":
        print(index, next(element))

遇到的问题：next()不适用于字符串，element+1也无法获取下一个元素，只能拿到标识的索引和内容，无法提取对应坐标值。

直接利用列表的索引定位，因为坐标值始终在对应标识的下一个位置，具体实现如下：

some_list = ["PointID:","1","'Y':", "1.134","'X':","1.223", "'Z':","1.0","PointID","2", "'Y':","1.4", "'X':","1.75","'Z':","1.0"]
output_lines = []

for index, element in enumerate(some_list):
    # 匹配坐标标识
    if element in ("'X':", "'Y':", "'Z':"):
        # 获取下一个元素作为坐标值
        coord_value = some_list[index + 1]
        # 处理标识格式，去掉引号
        coord_label = element.strip("'").strip(":") + ":"
        # 拼接成期望的格式
        output_line = f"{coord_label} {coord_value}"
        output_lines.append(output_line)
        # 打印输出
        print(output_line)

# 保存到TXT文件
with open("cad_coords.txt", "w") as f:
    f.write("\n".join(output_lines))

关键说明： #

• 通过enumerate获取元素的索引，当匹配到坐标标识时，用index+1直接取列表中的下一个元素，这就是对应的坐标值
• 用strip("'").strip(":")处理标识字符串，把'Y':转换成Y:，符合期望的输出格式
• 收集所有结果后，通过文件写入操作保存到TXT文件，方便CAD软件读取
