store loop result in variable,python

Question

i have a list of sentences called "data" and i carried out an operation of soundex.
i dont know how to store it in a variable.. here is my code:

for line in data:

    for word in line.split():

        print jellyfish.soundex(word)

that gives me a list of soundex codes for all words..

how do i store the results in a variable?? i have tried:

data_new = [(jellyfish.soundex(word) for word in line.split()) for line in data]

but that did not help.

Try list comprehension instead of generator expression: `data_new = [[jellyfish.soundex(word) for word in line.split()] for line in data]` — falsetru, Feb 08 '14 at 06:21

Remove the generator expression from within the comprehension:

data_new = [jellyfish.soundex(word) for line in data for word in line.split() ]

Use list comprehension instead of generator expression:

data_new = [[jellyfish.soundex(word) for word in line.split()] for line in data]

Or, if you want flat list:

data_new = [jellyfish.soundex(word) for line in data for word in line.split()]

could i get back my original list from this?? – Hypothetical Ninja Feb 08 '14 at 06:28
@Sword, What do you mean the original list? – falsetru Feb 08 '14 at 06:29
yeah.. for an entire intuition abt my problem check http://stackoverflow.com/questions/21628391/replace-words-using-soundex-python – Hypothetical Ninja Feb 08 '14 at 06:30
@Sword, If you mean get the `data` from the generated `data_new`. No you can't. (You may use `' '.joni(...)`, but it will not give you exactly same string because `str.split` remove consecutive whitespaces.) – falsetru Feb 08 '14 at 06:34
so how do i get alon with it? i was thinking of computing and comparing the soundex in the for loop itself . if it is same , str.replace it with right spelling.. wats ur say? – Hypothetical Ninja Feb 08 '14 at 07:12
@Sword, Do you want something like this: `data_new = [''.join(jellyfish.soundex(word) for word in line.split()) for line in data]` ? – falsetru Feb 08 '14 at 07:13

Remove the parentheses around (jellyfish.soundex(word) for word in line.split()), which is a generator expression (see for example generator comprehension). The result,

data_new = [jellyfish.soundex(word) for word in line.split() for line in data]

should give you what you seem to want.
