Deleting a string from a one list with strings/numbers-CodePudding

I have a list that looks like this -

item1,5,1,648,16,10,0,3,5,1,1,0,1,1,1,0,0,0,0,0,1,0,0,1,0,0
item2,3,1,29,3,6,0,0,3,1,0,0,1,0,1,0,0,0,0,0,1,0,0,0,1,0
item3,4,1,2388,20,8,2,0,3,1,1,0,0,1,0,0,0,0,0,0,1,1,0,0,0,0
item4,6,3,0,0,1,0,0,5,1,0,1,1,1,0,1,0,0,0,0,0,0,1,1,1,0

What would be the best way of deleting the "item" part of the list?

I've tried

del list[j][0]

But then I get "TypeError: 'str' object doesn't support item deletion"

I've tried

list[j].remove(list[j][0])

But then I get AttributeError: 'str' object has no attribute 'remove'

Pop doesn't seem to work either - AttributeError: 'str' object has no attribute 'pop'

Any ideas?

EDIT: So I've read in a list -

data = open("flags.features", 'r').readlines()

Then just split each line -

for i in data:
    input_list.append(i.split('\n')[0])

With an output of -

['item1,5,1,648,16,10,0,3,5,1,1,0,1,1,1,0,0,0,0,0,1,0,0,1,0,0',         'item2,3,1,29,3,6,0,0,3,1,0,0,1,0,1,0,0,0,0,0,1,0,0,0,1,0', 'item3,4,1,2388,20,8,2,0,3,1,1,0,0,1,0,0,0,0,0,0,1,1,0,0,0,0', 'item4,6,3,0,0,1,0,0,5,1,0,1,1,1,0,1,0,0,0,0,0,0,1,1,1,0', 'item5,3,1,0,0,6,3,0,3,1,0,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0', '

How about this?

data = open("flags.features", 'r').readlines()
input_list = []

for i in data:
    input_list.append(",".join(i.split('\n')[0].split(",")[1:]))

This outputs

['5,1,648,16,10,0,3,5,1,1,0,1,1,1,0,0,0,0,0,1,0,0,1,0,0',
 '3,1,29,3,6,0,0,3,1,0,0,1,0,1,0,0,0,0,0,1,0,0,0,1,0',
 '4,1,2388,20,8,2,0,3,1,1,0,0,1,0,0,0,0,0,0,1,1,0,0,0,0',
 '6,3,0,0,1,0,0,5,1,0,1,1,1,0,1,0,0,0,0,0,0,1,1,1,0']

CodePudding user response：

You may try this:

my_list = [x.split(",") for x in my_list]
my_list[j].pop(0)

CodePudding user response：

You could do:

list[j].pop(1) #the 1 can be replaced with any number

This will index the list then pop the item in that list off.
