linux - List of empty string returns non-zero length in python -


this question has answer here:

i have list of strings returned after command execution, split on '\n'.

listname = output.decode('utf8').rstrip().split('\n')

when print using print(listname), get

['']

clearly it's list containing empty string

because of getting len(listname) 1.

how remove empty string

i think looking for:

filter(none,output.decode('utf8').rstrip().split('\n'))

in details:

>>> filter(none, ["ford", "nissan", ""]) ['ford', 'nissan']

p.s. in python 3+ filter returns iterator, use list(filter(..)).
