[issue6743] pprint.pprint should support no objects to print blank lines & allow args

[Mary Stern]

Mary Stern  added the comment:

Sorry: you also need to print out the args! :) .. like this:

def pprint(object='\n', *args, stream=None, indent=1, width=80, depth=None):
"""Pretty-print a Python object to a stream [default is sys.stdout]."""
printer = PrettyPrinter(
stream=stream, indent=indent, width=width, depth=depth)
printer.pprint(object)
for arg in args:
printer.pprint(arg)

[issue6743] pprint.pprint should support no objects to print blank lines & allow args

[Mary Stern]

New submission from Mary Stern :

Using print in python 3 I would like to simple "replace" print with
pprint.pprint. However pprint cannot be called with no arguments, so
this cannot currently be done (the error is "TypeError: pprint() takes
at least 1 positional argument (0 given)").

A simple improvement is to allow no object to be passed in and pprint
would then print a newline rather than fail.

Another problem is that if you try this:

 print('hello', True)

and replace print with print, the second arg gets interpreted as the
"stream" parameter.


Both of the above can be fixed (I think) by changing pprint.py as follows:

instead of the current code:
def pprint(object, stream=None, indent=1, width=80, depth=None):

change to this:
def pprint(object='\n', *args, stream=None, indent=1, width=80, depth=None)

[issue5253] os.environ.get() doesn't handle default value

[Mary Stern]

New submission from Mary Stern :

os.environ.get('ENV_VAR, 'mydefault')

returns '' rather than 'mydefault' if not set.

It would be nice if this standard dict-style behavior was supported.

[issue5099] subprocess.POpen.__del__() AttribuetError (os module == None!)

[Mary Stern]

New submission from Mary Stern :

I was getting this error (while running my unit tests):

Exception exceptions.AttributeError: "'NoneType' object has no attribute
'error'" in > ignored

which I tracked down to the os module being set to None (yes really!) in
POpen._internal_poll() when called from Popen.__del__, so this line:

except os.error:

was generating the error.

I guess that the module is getting unloaded earlier somehow (maybe a
race condition)?
