Not really!

Of course you do not distribute .cs (or .vb) files when deploying your
application, but decompilers for .NET are plenty. Same for Java.

For C and the like, it is a little trickier, but the "decompiler " can
and will produce equivalent code. Better yet, just disassemble it.

What is done nowadays to make people's life harder (as in, they cannot
just copy and paste code) is to use an obfuscator. Are there any for
Python?

This is completely and utterly useless for passwords, though. If you
need to protect something, encrypt it. If it is on a server, you can
control access to the file via filesystem permissions.

Do not expect to keep the password secret if you are distributing it,
though :) I've cracked C programs, Clipper and Java almost
effortlessly. They were all custom programs where the sole developer
would put a password for administrative functions, just to be able to
charge money long after it was deployed.

Yes, but in .Net we have some strong dotfuscators that makes reverse
engineer really difficult.
In any way, it is not so easy to get to the source as .py files is.

I believe that shipping just the bytecode is a pretty effective way to
stop 99% of programmers from
reading your code. Yes, in theory they could decompile it, but in
practice, programmers are lazy.

99% of programmers won't read the code if you ship the source.

Look, I am so lazy that usually I don't read the source code, even if
it is there in plain!

Exactly.

I don't understand... how can they steal an idea? If somebody copies your
idea, you've still got it, it's not gone.

For companies, that may be one reason. For many companies, rightly so ...
