使用BufferedReader操作异常的最小python示例

import io

try:
    # 打开文件
    file = open("example.txt", "r")
    
    # 创建BufferedReader对象
    reader = io.BufferedReader(file)
    
    # 读取文件内容
    data = reader.read()
    
    # 关闭文件
    file.close()
    
    # 输出文件内容
    print(data)
    
except IOError as e:
    print("文件读取错误:", str(e))
    
except Exception as e:
    print("发生异常:", str(e))
