I have the next string
:
string = 'tuned 1372 root 6u REG 8,3 4096 102029349 /tmp/ffiabNswC (deleted)\ngmain 1372 2614 root 6u REG 8,3 4096 102029349 /tmp/ffiabNswC (deleted)\n'
I need to put every element of the string
into the list1[0][..]
, but when I see a new line '\\n', I have to put the next elements into list1[1][..]
A multi-dimensional list, like this:
list1 = [["tuned", "1372", "root", "6u", "REG", "8,3", "4096", "102029349", "/tmp/ffiabNswC", "(deleted)"],
["gmain", "1372", "2614", "root", "6u", "REG", "8,3", "4096", "102029349", "/tmp/ffiabNswC", "(deleted)"]]
I do it with split
, but it put me all in the same dimension.
Split first by a new line (to get the row), then split each element by space (to get each column):
data = "tuned 1372 root 6u REG 8,3 4096 102029349 /tmp/ffiabNswC (deleted)\ngmain 1372 2614 root 6u REG 8,3 4096 102029349 /tmp/ffiabNswC (deleted)\n"
parsed = [elements.split() for elements in data.strip().split("\n")] # `strip()` removes the last whitespace so we don't get blank elements
print(parsed)
# [['tuned', '1372', 'root', '6u', 'REG', '8,3', '4096', '102029349', '/tmp/ffiabNswC', '(deleted)'], ['gmain', '1372', '2614', 'root', '6u', 'REG', '8,3', '4096', '102029349', '/tmp/ffiabNswC', '(deleted)']]
The following function should do this for you:
f = lambda list: [sublist.split(' ') for sublist in list.split('\n')]
Just call it via f(string)
.
If additionally you don't want any empty entries in your sub-lists you could do
f = lambda list: [sublist.split(' ') for sublist in list.split('\n') if sublist]
Input:-
string = 'tuned 1372 root 6u REG 8,3 4096 102029349 /tmp/ffiabNswC
(deleted)\ngmain 1372 2614 root 6u REG 8,3 4096 102029349 /tmp/ffiabNswC
(deleted)\n'
Code: - Just write
mylist=string.split()
Output:-
[tuned
1372
root
6u
REG
8,3
4096
102029349
/tmp/ffiabNswC
(deleted)
gmain
1372
2614
root
6u
REG
8,3
4096
102029349
/tmp/ffiabNswC
(deleted)]
Since you want to split the string into lines, then the lines into words, you can use a comprehension
result = [line.split() for line in string.split('\n')]
Output:
[['tuned', '1372', 'root', '6u', 'REG', '8,3', '4096', '102029349', '/tmp/ffiabNswC', '(deleted)'],
['gmain', '1372', '2614', 'root', '6u', 'REG', '8,3', '4096', '102029349', '/tmp/ffiabNswC', '(deleted)'],
[]]
If you don't want that final blank (because of the last \\n
) you can just strip
it before split
ting.
Yo can use list comprehensions as the following:
string = 'tuned 1372 root 6u REG 8,3 4096 102029349 /tmp/ffiabNswC (deleted)\ngmain 1372 2614 root 6u REG 8,3 4096 102029349 /tmp/ffiabNswC (deleted)\n'
print [x.split() for x in string.strip().split('\n')]
output:
[['tuned', '1372', 'root', '6u', 'REG', '8,3', '4096', '102029349', '/tmp/ffiabNswC', '(deleted)'], ['gmain', '1372', '2614', 'root', '6u', 'REG', '8,3', '4096', '102029349', '/tmp/ffiabNswC', '(deleted)']]
Due to your help, I´ve tried to do a dictionary with the values inside a list and it´s great.
Here it is and it works. I´m starting to fall in love with list comprehension!
dict1 = { i.split()[0]: (i.split()[1:]) for i in data.strip().split('\n') }
Output:
dict1
{'gmain': ['1372',
'2614',
'root',
'6u',
'REG',
'8,3',
'4096',
'102029349',
'/tmp/ffiabNswC',
'(deleted)'],
'tuned': ['1372',
'root',
'6u',
'REG',
'8,3',
'4096',
'102029349',
'/tmp/ffiabNswC',
'(deleted)']}
