[Tutor] Portalocker

[Mike Wagman]

Does not seem to be working.

Can anyone send me a piece of code that will open a file, and when that
file is open - I can't open it from another python program.

[S***@aol.com]

import portalocker
file=open("C:\My Documents\log.txt", "r+")
portalocker.lock(file, portalocker.LOCK_EX)

Traceback (most recent call last):
File "<pyshell#13>", line 1, in ?
portalocker.lock(file, portalocker.LOCK_EX)
AttributeError: 'module' object has no attribute 'lock'

I rechecked to see if I installed the module correctly and I did. Anyone
know why this is happening? Thanks in advance.

Hi there,
Could you possibly post a URL for portalocker ??
At first glance I can hazard a guess, since I too have done such mistakes when
playing in the interpreter.

import portalocker
file=open("C:\My Documents\log.txt", "r+")
portalocker.lock(file, portalocker.LOCK_EX)

File "<pyshell#13>", line 1, in ?
portalocker.lock(file, portalocker.LOCK_EX)
AttributeError: 'module' object has no attribute 'lock'

The error message is pretty clear. You seem to be calling a non-existant
method in the module 'portalocker' called 'lock' ('module' object has no
attribute 'lock')

Normally, for me, something like this happens in the interpreter when I
stupidly try to use a method that belongs to a class with the same name is
the module. What I mean is, look at the portalocker module and see if there
is a class called 'portalocker' which you have to instantiate before calling
the 'lock' method on the instance.

Peace
