Python查找文件中连字符数字的范围

import re

def find_ranges_in_file(file_path):
    ranges = []
    pattern = re.compile(r'\b(\d+)-(\d+)\b')
    
    with open(file_path, 'r') as file:
        for line in file:
            matches = pattern.findall(line)
            for match in matches:
                start, end = int(match[0]), int(match[1])
                ranges.append((start, end))
    
    return ranges

# 示例文件内容
file_content = """
这是一个示例文件，包含一些范围数据：
1-5
10-15
20-25
"""

# 将示例内容写入临时文件
with open('temp.txt', 'w') as temp_file:
    temp_file.write(file_content)

# 查找文件中的范围
ranges = find_ranges_in_file('temp.txt')
print(ranges)  # 输出: [(1, 5), (10, 15), (20, 25)]
