[issue19810] adding an feature to python interpreter

2013-11-27 Thread madan ram 

New submission from madan ram:

I found that it will be useful to show the list of function arguments using 
inspect module. When the function executed by the user in interpreter as 
TypeError. 

ex: - 

def foo(a,b=4,c=hello):
... print a,b,c

foo()
Traceback (most recent call last):
  File stdin, line 1, in module
TypeError: foo() takes at least 2 arguments (0 given)

Rather the displaying like above it is will be much more readable to show as 
below.

foo()
Traceback (most recent call last):
  File stdin, line 1, in module
TypeError: foo() takes at least 1 arguments args=['a', 'b', 'c'], varargs=None, 
keywords=None, defaults=(4, 'hello') (0 given)

This will be advantageous when the user has forgotten what parameter to use for 
builtin function when working offline.

[issue19810] Adding a feature to python interpreter

2013-11-27 Thread R. David Murray 

R. David Murray added the comment:

That's much less readable than the output from pfydoc, which the user can 
access easily (via either help at the interpreter prompt or pydoc at the shell 
prompt).  So I'm -1 on this proposed change.
