Re: abspath returns different results when py_compile input path is different in Python?

so py_compile.compile() doesn't normalize the filename, but it will pass
the input filename to co_filename?

A code object has a co_filename attribute for use in creating
tracebacks. This path isn't necessarily fully qualified. Here are a
couple of examples using the built-in compile() function:

>>> compile('42', 'test.py', 'exec').co_filename
'test.py'
>>> compile('42', '/usr/local/bin/test.py', 'exec').co_filename
'/usr/local/bin/test.py'

py_compile.compile() does not normalize the filename.

abspath returns different results when py_compile input path is different in Python?

2018-02-12 Thread lampahome 
I want to know abspath of python script followed by steps below.

   1. *built it to byte code by py_compile.*
   2. *execute it to check abspath.*

But I got *2 results* when I execute it.I found the *results based on the
path of script* followed by py_compile.

Here is my script test.py :

import osimport inspect
print os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe(

Build it with py_compile, then got 2 results when I enter *different path
of test.py*:

*enter the folder and compile with only script name.*

[~]cd /usr/local/bin/[/usr/local/bin/]python -m py_compile
test.py[/usr/local/bin/]cd ~[~]python
/usr/local/bin/test.pyc/home/UserXX

*In other folder and compile with absolute script name.*

[~]python -m py_compile /usr/local/bin/test.py[~]python
/usr/local/bin/test.pyc/usr/local/bin

how come got 2 different results?
