Automatically Writing a Dictionary

[tonylabarbara at aol.com]

d = {}?
? for line in input:?
? key, value = line.split(',').rstrip('\n')?
? d[key] = value?



Thanks. That worked except for the rstrip. So I did this:


for line in input:

? line = string.rstrip(line, '\n')

? key, value = line.split(',')

? dictionary[key] = value



Thanks again,
Tony

Don't bother with the string (and as a side-note, it's bad style to mask the built-in dict() so I'll use "d"):?
?
? d = {}?
? for line in input:?
? key, value = line.split(',').rstrip('\n')?
? d[key] = value?
?
or even just?
?
? d = dict(line.split(',').rstrip('\n')?
? for line in input)?
?
using the aforementioned dict() function :-)?

You may want to clean it up a bit in case there are spurious leading/trailing spaces to be trimmed:?
?
? from string import strip?
? d = dict(map(strip, line.split(','))?
? for line in input)?
?
or even ignore lines with the wrong number of commas:?
?
? d = dict(map(strip, line.split(','))?
? for line in input?
? if line.count(',') == 1)?
?
or assume any extra commas are part of the value:?
?
? d = dict(map(strip, line.split(',',1))?
? for line in input?
? if line.count(',') > 0)?
