Python3从文本文件中筛选特定范围内的数字

import re

def filter_numbers(file_path, start_range, end_range):
    # 打开文本文件
    with open(file_path, 'r') as file:
        # 读取文件内容
        content = file.read()
        
        # 提取数字
        numbers = re.findall(r'\b([1-9]|[1-9][0-9]|100)\b', content)
        
        # 过滤范围内的数字
        filtered_numbers = [int(num) for num in numbers if start_range <= int(num) <= end_range]
        
        return filtered_numbers

# 示例用法
file_path = 'file.txt'
start_range = 10
end_range = 50

filtered_numbers = filter_numbers(file_path, start_range, end_range)
print(filtered_numbers)
