Python 中的回溯对象类型是什么?
What is the type of traceback objects in Python?
import sys
try:
raise Exception('foobar')
except:
info = sys.exc_info()
print(type(e[2])) # <class 'traceback'>
help(traceback) # NameError: name 'traceback' is not defined
Python 用于异常报告的回溯对象的类型究竟是什么?
sys.exc_info 上的文档提到了参考手册,但是虽然我找到了大量关于如何操作回溯实例的信息,但我希望能够访问该类型 (class)本身。
traceback
对象是类型模块下 TracebackType
的一个实例。
types.TracebackType
The type of traceback
objects such as found in sys.exc_info()[2]
.
>>> from types import TracebackType
>>> isinstance(info[2], TracebackType)
True
>>> TracebackType
<class 'traceback'>
因为 the name TracebackType
is basically an alias to the internal traceback
type and is set by raising an exception in types module. The actual traceback
type 可以在 CPython 代码中找到。
import sys
try:
raise Exception('foobar')
except:
info = sys.exc_info()
print(type(e[2])) # <class 'traceback'>
help(traceback) # NameError: name 'traceback' is not defined
