Re: [Tutor] [Linux] open a file in any home ~ ?

[Matthew White]

os.getenv('HOME') will return the user's home directory as long as that
environment variable is set.

you can also use the pwd module:

 pwd.getpwnam('mtw')
('mtw', 'x', 1000, 1000, ',,,', '/home/mtw', '/bin/bash')

-mtw

use os.path.expanduser(path)

Re: [Tutor] [Linux] open a file in any home ~ ?

Hi,

You can use expanduser() from os.path for this:

import os.path
homedir = os.path.expanduser('~user1')
file_to_open = os.path.join(homedir, '.myapp.conf')
f = open(file_to_open, 'r')

 Hello,

 I want to read a configuration file from a small python app (user
 preferences).

 The .myapp.conf is in the home folder of the user.

 if I do:

 f=open(/home/user1/.myapp.conf,r)  #it works

 obviously I won't know the home user folder name then I wanted to use:

 f=open(~/.myapp.conf,r)  # but it returns a IOError: [Errno 2] No such
 file or directory:

 How can I do to access this file whatever the user is ?

 Thanks for your help.

You can get the user name using getpass.getuser() as described in 
the OS topic of my tutor under the Securiity heading.

You can also try using os.getenv() or the os.environ variable 
to look up the HOME environment variable, also discussed 
in the OS topic.

Re: [Tutor] [Linux] open a file in any home ~ ?

[w chun]

we are all happy to help.  it is really good that you were able to get
it working so fast!  also, if you want to do any kind of pattern
matching with * or ?, then check out the glob module.

merci!  le livre does not look that good from here... it is a mess
and i have to clean it up before giving it to the publisher!  :-)

cheers,

Neat Wesley, I've  never noticed that one before.
