Question

os.stat returns st_mtime and st_ctime attributes, the modification time is st_mtime and st_ctime “change time” on POSIX.
is there any function that return the creation time of a file using python and under Linux?

Answer 1

You probably can’t.:

3.1)  How do I find the creation time of a file?

      You can't - it isn't stored anywhere.  Files have a last-modified
      time (shown by "ls -l"), a last-accessed time (shown by "ls -lu")
      and an inode change time (shown by "ls -lc"). The latter is often
      referred to as the "creation time" - even in some man pages -
      but that's wrong; it's also set by such operations as mv, ln,
      chmod, chown and chgrp.

      The man page for "stat(2)" discusses this.
