python - pandas - convert string into list of strings -


i have 'file.csv' file read pandas:

title|tags t1|"[tag1,tag2]" t1|"[tag1,tag2,tag3]" t2|"[tag3,tag1]"

using

df = pd.read_csv('file.csv', sep='|')

the output is:

  title              tags 0    t1       [tag1,tag2] 1    t1  [tag1,tag2,tag3] 2    t2       [tag3,tag1]

i know column tags full string, since:

in [64]: df['tags'][0][0] out[64]: '['

i need read list of strings ["tag1","tag2"]. tried solution provided in this question no luck there, since have [ , ] characters mess things.

the expecting output should be:

in [64]: df['tags'][0][0] out[64]: 'tag1'

you can split string manually:

>>> df['tags'] = df.tags.apply(lambda x: x[1:-1].split(',')) >>> df.tags[0] ['tag1', 'tag2']

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
