traceback

问题 I have a code which, at some point shows a warning, I think that it is having a problem calculating a mean() I would like to know if there is any way to force python to tell me where, or which line, or whatever more information than just this message: C:\Python27\lib\site-packages\numpy\core\_methods.py:55: RuntimeWarning: Mean of empty slice. warnings.warn("Mean of empty slice.", RuntimeWarning) C:\Python27\lib\site-packages\numpy\core\_methods.py:79: RuntimeWarning: Degrees of freedom <= 0

问题 The following snippet: import traceback def a(): b() def b(): try: c() except: traceback.print_exc() def c(): assert False a() Produces this output: Traceback (most recent call last): File "test.py", line 8, in b c() File "test.py", line 13, in c assert False AssertionError What should I use if I want the complete stack trace including the call to a? If it matters I have Python 2.6.6 edit: What I'd like to get is the same information I'd get if I left the try except out and let the exception

问题 Consider the following Python program: code = """ def test(): 1/0 """ filename = "<test>" c = compile(code, filename, 'exec') exec(c) import linecache linecache.cache[filename] = (len(code), None, code.splitlines(keepends=True), filename) import traceback print("Traceback from the traceback module:") print() try: test() except: traceback.print_exc() print() print("Regular traceback:") print() test() I am dynamically defining a function that raises an exception and adding it to the linecache .

问题 There is a log file from jenkins. and I want to extract all the traceback from the log file. (many different kinds of tracebacks may be appear in the log). How to write the python regex? I have tried below method, but it works not well. trace_regex = r'^Traceback[\s\S]*Error.*|^Traceback[\s\S]*timeout.*|^Traceback[\s\S]*HunterDeviceOffline.*|Traceback[\s\S]*Exception.*|Traceback[\s\S]*BadStatusLine.*|Traceback[\s\S]*NoSuchDevice.*|Traceback[\s\S]*AuthenticationsFail.*' trace = re.findall

问题 I am writing a compiler in Ocaml. The tracback works well when I compile and test it with make in a terminal, for instance: export OCAMLRUNPARAM=b ./Simpler-Basic test.sib Fatal error: exception Match_failure("interp.ml", 45, 21) Called from file "interp.ml", line 97, characters 72-86 Called from file "list.ml", line 74, characters 24-34 Called from file "interp.ml", line 108, characters 9-35 Called from file "main.ml", line 54, characters 4-17 make: *** [all] Error 2 But when I compile and

问题 I am trying to read in a document containing product data and print certain product's data out. Problem is, I can't seem to get it read in without error. I am just trying to print the first 100 characters just to get it read in so I can then figure out what specifically I need to print and how to pull it out of the file. But I am stuck reading it in. The document is in UTF-8, or it should be... what am I missing? Here is my code: products = open('products.csv') productsread = products.read()

问题 Here's the last few frames of a typical Ruby on Rails traceback: And here are the last few frames of a typical Nevow traceback in Python: It's not just the web environment either, you can make similar comparisons between ipython and irb. How can I get more of these sorts of details in Ruby? 回答1: AFAIK, once an exception has been caught it's too late to grab the context in which it was raised. If you trap the exception's new call, you could use evil.rb's Binding.of_caller to grab the calling
