There is no need to use eval on that, you could just use:

f = open('file.conf')
conf = {}
for line in f:
key, value = line.split('=', 1)
conf[key] = value

a bit more obscure:

conf = dict(line.split('=', 1) for line in open('file.conf'))

   I have one normal text file. I need to parse the file, that

suppose that below is the normal textfile

name='adf'
id  =1
value=344



there are many approaches to config files. But
in your special example, it looks like a simplified
mapping, so

parsed=eval("dict(%s)" % ",".join(line
 for line
 in file("textfile")
 if line.strip()
 )
)

>>> parsed['name']
'adf'

but of course eval() is dangerous, so feel free to
explore more then this one solution.

parse a normal textfile

[devi thapa]

hi all

   I have one normal text file. I need to parse the file, that too
in an associative way .
suppose that below is the normal textfile

name='adf'
id  =1
value=344

So when I give 'name' as an input, the output must be 'adf'

so please help me out with this.

regards,
devi.
