Help with ConfigParser

[Stephen Boulet]

I'm having a bit of trouble getting my head around the ConfigParser module.
I have a very simple configuration file; maybe the easiest thing to do
would be to show that:

============
# Add a local directory to be backed up followed
# by the directory name on the FTP server.
#
# Example: /home/joe/digital photos = photos

[Backups]
/home/stephen/photos/digital camera = photos
/home/stephen/documents/tax documents = taxes
============

I just want to retrieve the information in the backups section. Thanks.

Which one? ;-) There are two.

You can list the keys (LHS) and the values (RHS) or both.

import ConfigParser
configFile = open('/etc/g2ctech/cvs.cf')
config = ConfigParser.ConfigParser()
config.readfp(configFile)
config.items('default') [('forbidden_exts', "['.doc', '.xls', '.ppt']"), ('cvsroot', '/home/cvs')]
config.items('get_data_from_mail')

[('maildir',
'/home/godoy/empresa/clientes/dataprev/cvs-import/tests/sample')]

Default is a section as well as get_data_from_mail.


Be seeing you,

What are you looking up, and what's the invariant (what's the lookup
key)? I'd write the config file like this:

[Backups]
photos = /home/stephen/photos/digital camera
taxes = /home/stephen/documents/tax documents

Lookup keys are on the left, and configuration data is on the right.

From your example though, it looks like you don't have specific
lookup keys. You're just storing an arbitrary set of paired data.
You could use an "items('Backups')" method call to get a list of
(key, value) pairs which you could iterate over.

Just the other way round:

photos=/home/...

A minimal example:

from ConfigParser import ConfigParser

CONFIG_FILE = "boulet.ini"

# generate sample data
f = file(CONFIG_FILE, "w")
f.write("""
[Backups]
photos=/home/stephen/photos/digital camera
taxes=/home/stephen/documents/tax documents
""")
f.close()

# retrieve configuration
p = ConfigParser()
p.read(CONFIG_FILE)

# a single value
print "Photos:", p.get("Backups", "photos")

# a complete section
print "Backups:"
for key, value in p.items("Backups"):
print "\t%r --> %r" % (key, value)
