python - Converting list of list into 2 independent lists -

-



i have list of lists looks this:

lol=[['"buy":17'], ['"hold":18'], ['"sell":3']]

is there simple way convert list of lists 2 independent lists this?:

list1=["buy","hold","sell"] list2=[17,18,3]

first tried replace on list:

lol.replace('[','').replace(']','')

but outputed 'list' object has no attribute 'replace'

then thought use regular expressions on lol @ least obtaining numbers in independent list following code: 

re.findall('\d{1,2}',lol.string)

but returned outputed expected string or bytes-like object

you can split strings on ':' , use ast.literal_eval produce final output:

import ast  l1, l2 = zip(*[map(ast.literal_eval, lst[0].split(':')) lst in lol]) print(l1, l2) # ('buy', 'hold', 'sell'), (17, 18, 3)

python - Read npy file directly from S3 StreamingBody -

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
