Like p4ruby, parameters are an array of strings:

Instead of:

>             self.p4Obj.run("verify", "-q //depot/P4Tools/... >
> \\logs\\verify.log")

Try:

            self.p4Obj.run("verify", "-q", "//depot/P4Tools/...")

Second thing is that the results are returned as a list from the
command:

>>> print p4c.run_verify("-q", "//depot/Jam/...")
[]

In the above case there are no errors. Then I move a file on the server
to
provoke errors and get:

>>> print p4c.run_verify("-q", "//depot/Jam/...")

> Also, is there a P4Python way to execute p4d?

That would be via a system call as opposed to via p4python.

For a good cross platform type way see
http://www.ravenbrook.com/project/p4dti/master/test/test_p4dti.py (which
has
been used as the base for the test suite included with p4python itself):

        if os.name == 'nt':
            # p4d on Windows doesn't detach, to we can't use "system"
            # to start it.  RB 2002-10-28
            import win32api
            if unicode:
                win32api.WinExec("%s -r %s -xi" %
                                 (config.p4_server_executable,
self.p4dir))
            win32api.WinExec("%s -p 0.0.0.0:%d -r %s" %
                             (config.p4_server_executable, port,
                              self.p4dir))
            time.sleep(2)
        else:
            # For some reason, p4d doesn't detach properly when called
            # by os.popen4, so we have to use os.system here instead
            # of self.system.  RB 2002-10-29
            if unicode:
                os.system('%s -r "%s" -xi >> %s 2>&1' %
                          (config.p4_server_executable,
                           self.p4dir,
                           log_filename))
            os.system('%s -d -p 0.0.0.0:%d -r "%s" >> %s 2>&1' %
                      (config.p4_server_executable,
