Getting a python traceback without an exception

Question

Suppose you have these modules:

module1.py

import module2

def a():
    module1.b()

def c():
    print \"Hi guys!\"

module2.py

Answer 1

traceback.print_stack works nicely for me:

>>> import traceback
>>> def what():
...    traceback.print_stack()
... 
>>> def hey():
...    what()
... 
>>> hey()
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in hey
  File "<stdin>", line 2, in what

UPDATE:

You've made it clear you really don't want a traceback. You want tracing information. Here's a way you can get some trace info:

#tracetest.py

def what():
    return 3

def hey():
    return what()

def yo():
    return hey()

import trace
tracer = trace.Trace()
tracer.run("yo()")
r = tracer.results()
r.write_results()

and running the above:

$ python tracetest.py
 --- modulename: tracetest, funcname: <module>
<string>(1):   --- modulename: tracetest, funcname: yo
tracetest.py(8):     return hey()
 --- modulename: tracetest, funcname: hey
tracetest.py(5):     return what()
 --- modulename: tracetest, funcname: what
tracetest.py(2):     return 3
