Couple quick tips:
1. IPython's `%xmode verbose` automatically gives extra detailed tracebacks
that are particularly useful for this:
In [25]: x=0
In [26]: y=1
In [27]: y/x
---------------------------------------------------------------------------
ZeroDivisionError Traceback (most recent call last)
<ipython-input-27-d2d3fa2acc3f> in <module>()
----> 1 y/x
ZeroDivisionError: division by zero
In [28]: %xmode verbose
Exception reporting mode: Verbose
In [29]: y/x
---------------------------------------------------------------------------
ZeroDivisionError Traceback (most recent call last)
<ipython-input-29-d2d3fa2acc3f> in <module>()
----> 1 y/x
global y = 1
global x = 0
ZeroDivisionError: division by zero
2. IPython's sys_info() prints system details:
In [20]: from IPython import sys_info
In [21]: print(sys_info())
{'commit_hash': '36ab971de',
'commit_source': 'repository',
'default_encoding': 'UTF-8',
'ipython_path': '/Users/fperez/dev/ipython/ipython/IPython',
'ipython_version': '6.2.0.dev',
'os_name': 'posix',
'platform': 'Darwin-16.7.0-x86_64-i386-64bit',
'sys_executable': '/Users/fperez/usr/conda/bin/python',
'sys_platform': 'darwin',
'sys_version': '3.6.2 |Anaconda, Inc.| (default, Oct 5 2017, 03:00:07) \n'
'[GCC 4.2.1 Compatible Clang 4.0.1
(tags/RELEASE_401/final)]'}
In fact, IPython's crash handler (its internal sys.excepthook) consists
more or less of a traceback made with verbose mode + the output of
sys_info, and it can be very handy.
