It depends somewhat on the format of the whole file, but for a first

conf = {}
for line in file('test.conf'):
   vals = line.split('=')
   if len(vals)!=2: continue
   key, val = vals
   conf[key.strip()] = val.strip()

print 'Server is', conf['server']

Now some comments

conf = {}    #conf is a dictionary mapping keys to values
for line in file('test.conf'):
   vals = line.split('=')     #split the lines at the equal token
   if len(vals)!=2: continue  #a valid split has two entries
   key, val = vals            # the key and the value
   conf[key.strip()] = val.strip()   #enter the result to tin the
                                     #dictionary, removing whitespace

# show that it worked
print 'Server is', conf['server']

You'll need a recent version of python to split on an arbitrary token.
