Why the file mode of .pyc files has x?

[Peng Yu]

Hi,

It is strange that the file mode of .pyc files are changed to
executable (x mode) after the corresponding .py files have been run. I
have the follow python, which is compiled from source code by me.

$ python --version
Python 2.6.2

Should .pyc files have the x mode?

Regards,
Peng
