This question sounds like "are cars usually red"? There are without a doubt a lot of red cars, but this means nothing if you what to know if
this specific car is red or not. What you are interested in is, if the software is installed on the specific system you want to run some script on. If some other systems have it or not doesn't matter.
What "UNIX" constitutes is defined in the "Single Unix Specification", the "POSIX" specification and similar documents. Today a UNIX system is not required to use some specific (AT&T-) code, but to react in a (thusly) specified way. "awk" is part of this specification, "perl" is not. And neither is "python". If you want to write portable scripts you should consider using the POSIX shell (which resembles mostly the ksh88).

The system i use most - AIX - definitely doesn't have it in the default install and for AIX - as well as any other systems i use - the term "default install" is meaningless. When i install a production system i use a carefully crafted absolute-minimum-image ("golden image") and install of this what is needed. What can be expected because of the POSIX specification is there (all tools listed as "mandatory"), but not more. Everything installed will have to be maintained, can break, etc. and if you have thousands of systems in a data center (quite the common case) you want to keep the things which can break at an absolute minimum.
I hope this helps.

pygettext
PYGETTEXT(1) General Commands Manual PYGETTEXT(1)
NAME
pygettext - Python equivalent of xgettext(1)
SYNOPSIS
pygettext [OPTIONS] INPUTFILE ...
DESCRIPTION
pygettext is deprecated. The current version of xgettext supports many languages, including Python.
pygettext uses Python's standard tokenize module to scan Python source code, generating .pot files identical to what GNU xgettext generates
for C and C++ code. From there, the standard GNU tools can be used.
pygettext searches only for _() by default, even though GNU xgettext recognizes the following keywords: gettext, dgettext, dcgettext, and
gettext_noop. See the -k/--keyword flag below for how to augment this.
OPTIONS
-a, --extract-all
Extract all strings.
-d, --default-domain=NAME
Rename the default output file from messages.pot to name.pot.
-E, --escape
Replace non-ASCII characters with octal escape sequences.
-D, --docstrings
Extract module, class, method, and function docstrings. These do not need to be wrapped in _() markers, and in fact cannot be for
Python to consider them docstrings. (See also the -X option).
-h, --help
Print this help message and exit.
-k, --keyword=WORD
Keywords to look for in addition to the default set, which are: _
You can have multiple -k flags on the command line.
-K, --no-default-keywords
Disable the default set of keywords (see above). Any keywords explicitly added with the -k/--keyword option are still recognized.
--no-location
Do not write filename/lineno location comments.
-n, --add-location
Write filename/lineno location comments indicating where each extracted string is found in the source. These lines appear before
each msgid. The style of comments is controlled by the -S/--style option. This is the default.
-o, --output=FILENAME
Rename the default output file from messages.pot to FILENAME. If FILENAME is `-' then the output is sent to standard out.
-p, --output-dir=DIR
Output files will be placed in directory DIR.
-S, --style=STYLENAME
Specify which style to use for location comments. Two styles are supported:
o Solaris # File: filename, line: line-number
o GNU #: filename:line
The style name is case insensitive. GNU style is the default.
-v, --verbose
Print the names of the files being processed.
-V, --version
Print the version of pygettext and exit.
-w, --width=COLUMNS
Set width of output to columns.
-x, --exclude-file=FILENAME
Specify a file that contains a list of strings that are not be extracted from the input files. Each string to be excluded must
appear on a line by itself in the file.
-X, --no-docstrings=FILENAME
Specify a file that contains a list of files (one per line) that should not have their docstrings extracted. This is only useful in
conjunction with the -D option above.
If `INPUTFILE' is -, standard input is read.
BUGS
pygettext attempts to be option and feature compatible with GNU xgettext where ever possible. However some options are still missing or
are not fully implemented. Also, xgettext's use of command line switches with option arguments is broken, and in these cases, pygettext
just defines additional switches.
