That sounds a good question to me. Not totally sure whether my understanding is correct (then I will need to scour for those dust-covered software engineering textbooks for that), but here is my interpretation of some terminologies:

- Programming is the action of assembling instructions to realize some desired functionality, the exact instructions and syntax of which depending on the language and environment involved.

- Software development is a process which spans the entire software lifecycle, in which some software is built as deliverables as part of the process. Programming is the most important part of the process, but is just one part of the process. Planning, testing etc. are also part of the software development process. Post-development such as customer support, post-development reviews and maintenance are usually considered part of the software lifecycle, and thus should be considered part of the software development process as well.

- Software engineering refers to the application of engineering principles to the software development process, to result in software whose functionalities meeting the prescribed specifications, whose quality can be objectively quantized, and development costs can be within budget. It is just like the process of constructing a house. You won't leave until you have started the process and find that the bricks cannot support the walls. For software, identically, some engineering planning process precedes the implementation stage to ensure that the process may result in software that is implemented correctly, on time and within budget.

So software engineering is usually seen as a more "scientific" or "systematic" means to build software, as opposed to a more ad-hoc fashion as amateur developers usually do.

NAME

       py3compile - byte compile Python 3 source files

SYNOPSIS

          py3compile [-V [X.Y][-][A.B]] DIR_OR_FILE [-X REGEXPR]

          pycompile -p PACKAGE

DESCRIPTION

       Wrapper around Python standard library's py_compile module to byte-compile Python 3 files.

OPTIONS

       --version
              show program's version number and exit

       -h, --help
              show this help message and exit

       -f, --force
              force rebuild of byte-code files even if timestamps are up-to-date

       -O     byte-compile to .pyo files

       -q, --quiet
              be quiet

       -v, --verbose
              turn verbose mode on

       -p PACKAGE, --package=PACKAGE
              specify Debian package name whose files should be bytecompiled

       -V VRANGE
              force  private  modules to be bytecompiled with Python 3 version from given range, regardless of the default Python 3 version in the
              system. If there are no other options, bytecompile all public modules for installed Python 3 versions that match given range.   VER-
              SION_RANGE examples:

                 o 3.1    version 3.1 only,

                 o 3.1-3.3        version 3.1 or 3.2,

                 o -4.0   all supported 3.X versions

       -X REGEXPR, --exclude=REGEXPR
              exclude items that match given REGEXPR. You may use this option multiple times to build up a list of things to exclude
