I have the following list;
lst = ["['atama', 'karada', 'kami', 'kao', 'hitai', 'me', 'mayu', 'mabuta', 'matsuge', 'hana']",
"['head', 'body', 'hair', 'face', 'forehead', 'eye', 'eyebrow', 'eyelid', 'eyelash', 'nose']"]
I need to get the contents of each item set as a list, so that I can print the items individually. Eg.
for item in lst:
for word in list(item):
print word
>>
atama
karada
kami
kao
etc.
Any ideas how I could format the str(item)|s to lists once again?
>>> import ast
>>> L = ["['atama', 'karada', 'kami', 'kao', 'hitai', 'me', 'mayu', 'mabuta', 'matsuge', 'hana']",
"['head', 'body', 'hair', 'face', 'forehead', 'eye', 'eyebrow', 'eyelid', 'eyelash', 'nose']"]
>>> for item in L:
for word in ast.literal_eval(item):
print word
atama
karada
kami
kao
hitai
me
mayu
mabuta
matsuge
hana
head
body
hair
face
forehead
eye
eyebrow
eyelid
eyelash
nose
I can think of several methods:
1) Manually extract each list item:
lst = [[item.strip()[1:-1] for item in element[3:-3].split(',')] for element in lst]
2) Use eval:
lst[:] = eval(lst[0]), eval(lst[1])
3) Use json:
import json
lst = [json.loads(i) for i in lst]
Methods 1 or 3 are preferred. eval is unsafe, as any string passed to eval will be (surprise, surprise) evaluated. Only use eval if you have complete control over what is being passed to it.
4) Another solution that occured to me, use regular expressions:
import re
lst = [re.findall("['\"](\w+)['\"]", item) for item in lst]
(one, two) = (list(lst[0]), list(lst[1]))
