Python---操作异常

import sys,time
import traceback

def func(a, b):
    return a / b

if __name__ == "__main__":
    try:
        func(1, 0)
    except Exception as e:
        print('***', type(e), e, '***')

        print("***traceback.print_exc():*** ")
        # traceback.print_exc()
        traceback.print_exc(limit=1, file=sys.stdout)
        time.sleep(1)

        print("***traceback.format_exc():*** ")
        print(traceback.format_exc())
        time.sleep(1)

        print("***traceback.print_exception():*** ")
        traceback.print_exception(*sys.exc_info())

# 1.traceback.print_exc()：直接打印，可接受file参数直接写入到一个文件中。比如：traceback.print_exc(file = open("tb.txt","w+"))。
# 2.traceback.format_exc()：返回字符串。是把异常栈以字符串的形式返回，print(traceback.format_exc()) 就相当于traceback.print_exc()。
# 3、print_exception()：traceback.print_exc()实现方式就是traceback.print_exception(sys.exc_info())，可以点sys.exc_info()进去看看实现。
