File to Dictionary?

[Dekudude]

Hi there, everyone! I was wondering... How would I go about writing a script that creates a dictionary from a file?

EXAMPLE FILE:

google
start http://www.google.com
 
yahoo
start http://www.yahoo.com
 
c drive
start "C:\"
 

I want to turn a file like that into a dictionary. Example:

{'google': 'start http://www.google.com', 'yahoo': 'start http://www.yahoo.com', 'c drive': 'start "C:\"'}

How would I do this? Thanks a lot for your help!

Something like this would work...

>>> f = open('fhtodict', 'w')
>>> f.write('google\nstart http://www.google.com\n\nyahoo\nstart http://www.yahoo.com\n\nc drive\nstart "C:\\"\n')
>>> f.close()
>>> fd = {}
>>> f = open('fhtodict', 'r')
>>> for line in f:
...     if line[ : 5 ] != 'start' and not line.isspace():
...         key = line.strip()
...         fd[ key ] = ''
...         line = f.next()
...         fd[ key ] = line[ line.find( 'start' ) + len( 'start' ) + 1 : ].strip()
...     
>>> fd
{'google': 'http://www.google.com', 'c drive': '"C:\\"', 'yahoo': 'http://www.yahoo.com'}
>>>

Thank you! However, that's not exactly what I want. The file was just an example. The second line of each "block" won't always start with "start"... it just will sometimes. I need it to basically search for the line breaks, and split that apart, not the terms.

Make sense?

Here's another example:

s = '''
google
start http://www.google.com
 
yahoo
start http://www.yahoo.com
 
c drive
start "C:\"'''
 
sList = [item for item in s.split('\n') if item]
dd = {}
 
while sList:
    key = sList.pop(0)
    dd[key] = sList.pop(0).split(' ')[-1]
 
print dd    

Output:
>>> {'google': 'http://www.google.com', 'c drive': '"C:"', 'yahoo': 'http://www.yahoo.com'}

Yours works, but how do I read from an external file? This only works if the commands are built directly into the script, which I don't want. :P

Something like this will read a file and create a list equivalent to my earlier post:

sList = [item for item in [line.strip() for line in open(file_name)] if item]

I think it works. Thank you very, very much!
