如何在引发异常时修改Python跟踪对象？

import traceback

try:
    # 引发异常的代码
    pass
except Exception as e:
    # 打印异常信息
    traceback.print_exc()

import traceback

try:
    # 引发异常的代码
    pass
except Exception as e:
    # 获取异常信息并格式化
    error_info = traceback.format_exc()
    print(error_info)

import traceback

try:
    # 引发异常的代码
    pass
except Exception as e:
    # 获取异常跟踪对象
    tb = sys.exc_info()[2]
    # 打印异常跟踪对象
    traceback.print_tb(tb)

import traceback

try:
    # 引发异常的代码
    pass
except Exception as e:
    # 获取异常跟踪对象
    tb = sys.exc_info()[2]
    # 提取异常跟踪对象中的信息
    tb_info = traceback.extract_tb(tb)
    # 打印异常跟踪对象中的信息
    print(tb_info)

import traceback

try:
    # 引发异常的代码
    pass
except Exception as e:
    # 获取异常跟踪对象
    tb = sys.exc_info()[2]
    # 格式化异常跟踪对象
    tb_info = traceback.format_tb(tb)
    # 打印异常跟踪对象中的信息
    print(tb_info)
