场景：用于读取包含空格分隔数据的TXT文件，并将其转换为结构化JSON文件
一、TXT文件转换为JSON数组
1.txt文件内容
地点A 116.405285 39.904989 43.5
地标B 121.473701 31.230416 4.2
观测点C 113.264385 23.129112 12.8

# @Software: PyCharmimport jsondef txt_to_json(input_file, output_file):"""将TXT文件转换为JSON格式:param input_file: 输入文件路径（如input.txt）:param output_file: 输出文件路径（如output.json）"""# 定义一个列表data_list = []# 读取文件并逐行处理with open(input_file, 'r', encoding='utf-8') as f:for line in f:# 去除首尾空白字符并按空格分割parts = line.strip().split(" ")# 验证数据格式（需包含至少4列）if len(parts) >= 4:attribute = parts[0]try:# 提取经度、纬度、高度并转换为浮点数longitude = float(parts[1])latitude = float(parts[2])height = float(parts[3])# 构建JSON对象data = {"属性名": attribute,"经度": longitude,"纬度": latitude,"高度": height}data_list.append(data)except ValueError:print(f"数据格式错误，跳过行：{line}")# 生成JSON文件with open(output_file, 'w', encoding='utf-8') as json_f:json.dump(data_list, json_f, ensure_ascii=False, indent=4)
3.输出结果
[{"属性名": "地点A","经度": 116.405285,"纬度": 39.904989,"高度": 43.5},{"属性名": "地标B","经度": 121.473701,"纬度": 31.230416,"高度": 4.2},{"属性名": "观测点C","经度": 113.264385,"纬度": 23.129112,"高度": 12.8}

3.输出结果
{"地点A": {"经度": 116.405285,"维度": 39.904989,"高度": 43.5},"地标B": {"经度": 121.473701,"维度": 31.230416,"高度": 4.2},"观测点C": {"经度": 113.264385,"维度": 23.129112,"高度": 12.8}
