[issue22672] float arguments in scientific notation not supported by argparse

New submission from Jacopo Nespolo: Argparse fails to recognise negative numbers in scientific notation as valid numbers. Example: Suppose the program test.py has this option. par.add_argument('-a', type=float) then './test.py -a -1e5' will fail, as well as -1.0e-4, -.5E+4 and variations

Re: PYTHONPATH: dev and prod

1. How you run -- 'launch' -- the code -- from py and from prod when I have to test I use python any_script.py but in production there is a c++ program that is able to wrap and run python code (the technical details are a bit beyond my knowledge) 2. What error you get when I run as python

PYTHONPATH: dev and prod

/prod/myscripts/any_script.py, every import will look at PYTHONPATH and therefore it will load the modules from /py/mylib. On the contrary I want to load it from /prod/mylib. Is there an elegant way to cope with this? thanks, Jacopo -- http://mail.python.org/mailman/listinfo/python-list

RabbitMQ vs ApacheQpid (AMQP)

is already handled by the Messaging system and I don’t need to take care of it in my components (they keep waiting for a message, when they get it they are fully engaged in processing and they cannot do much more). Thanks, Jacopo -- http://mail.python.org/mailman/listinfo/python-list
