Compiling main script into .pyc

[Sam]

One thing I observe about python byte-code compiling is that the main script does not gets compiled into .pyc. Only imported modules are compiled into .pyc.

May I know how can I compile the main script into .pyc? It is to inconvenience potential copy-cats.

Duh? Just import it!

The standard library has the compileall module that can be used to
create .pyc files from .py files, but as we've been discussing in
another thread, you may not want .pyc files.

What if you want to just compile it? Importing will run it!

Importing will only run the portion of the code not protected by

if __name__ == "__main__":

Write the main script as

def main(): ...
if __name__ == '__main__': main()

The difference between merely compiling 'def main' and executing it is
trivial.

Or don't bother compiling and write main.py as one line:
from realmain import start; start()

Importing will only run the portion of the code not protected by

if __name__ == "__main__":

Nevertheless, there is no need to run *any* of the code just to compile
it.


[steve@ando ~]$ cat sample.py
print("Hello!")

[steve@ando ~]$ ls sample.pyc
ls: sample.pyc: No such file or directory
[steve@ando ~]$ python -m compileall sample.py
Compiling sample.py ...
[steve@ando ~]$ ls sample.p*
sample.py sample.pyc
[steve@ando ~]$ python sample.pyc
Hello!

[steve@ando ~]$ cat sample.py
print("Hello!")

[steve@ando ~]$ ls sample.pyc
ls: sample.pyc: No such file or directory
[steve@ando ~]$ python -m compileall sample.py
Compiling sample.py ...
[steve@ando ~]$ ls sample.p*
sample.py sample.pyc
[steve@ando ~]$ python sample.pyc
Hello!

Cool! Now I can distribute my application as a pre-compiled "binary"
just like I do for <insert language/platform/OS here>.
