How to Install pytz/dateutil python modules

[guardian]

Sorry I'm a bit lost with FreeBSD, I can do this with Windows or Linux, but I need a bit of help with FreeBSD/pfSense.

I'm doing some custom scripting, and I need to be able to convert from local time (both my local time, and anther server that is in another time zone)to gmt.  Unfortunately datetime.strptime "%z" doesn't work, so it looks like I need to resort to either pytz or dateutil module which isn't part of the standard library.

Is there an easy way to install modules?  Should I install pip?  (Is this easy to do?/How?)

Best way to deal with system updates if I do?

I would like to make the least change possible to the system.

Thanks.

@RonpfS:

python2.7 -m ensurepip

Thanks…

For the benefit of the other noobs:

python2.7 -m ensurepip

• installs pip

python2.7 -m pip install pytz

• installs module pytz

Follow up questions:

When I ran the install I got the following mesages:
Successfully installed pytz-2016.6.1
You are using pip version 8.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'pip install –upgrade pip' command.

Should I upgrade pip as suggested, or is this likely to cause trouble?

Will these changes survive an upgrade, or do they need to be reapplied?

Thanks.

I just updated  ::)

pkg install py27-dateutil
or
pkg install py27-pytz

This won't work for all python modules, but there are a number of pre-packaged ones including these.
