Is it possible to split and put the rest to list?

python split string first and rest
split list into multiple lists python
python list
python split string by space
set list value python
string into list python
python delimiter split
python split string by character

I'm trying to process a line like this

item1 item2 item3 item4_1 item4_2 item4_3 ...

And the code is like this

data = '''item1 item2 item3 item4_1 item4_2 item4_3'''
for row in data.split("\n"):
    (item1, item2, item3, item4_list) = row.split(' ')

It looks like python can't unpack the rest of the items to a list, any ideas?

If you use two steps, and maxsplit for str.split() this can be python 2 or 3 like:

data = '''item1 item2 item3 item4_1 item4_2 item4_3'''
for row in data.split("\n"):
    item1, item2, item3, item4_list = row.split(' ', 3)
    item4_list = item4_list.split(' ')
    print(item1, item2, item3, item4_list)
Results:
item1 item2 item3 ['item4_1', 'item4_2', 'item4_3']

How to use Split in Python, The split() method in Python returns a list of the words in the string/line , separated by In simpler terms, the separator is a defined character that will be placed In the above program maxsplit is 2, the first two string are split and rest of them  How we’d split it: Fairfax and Loudon counties, then everything else. Name of the new state: Nova Advantages: Nova could devote its tax revenue to expanding the DC Metro and maybe, possibly, not becoming the LA of the East. Virginians could avoid the mockery of their other southern friends for being a blue state,

As suggested by student, you want to use extended unpacking syntax—that is, you can put *rest directly in the target list (the same way you use *args in a function definition), and it will soak up the rest of the values:

item1, item2, item3, *item4_list = row.split(' ')

If you need something that works in Python 2, there isn’t anything as nice. (They wouldn’t have added extended unpacking if there were already a way to do it that’s just as nice…) The simplest solution here is probably to do it in two steps, using the max-splits argument to split:

item1, item2, item3, rest = row.split(' ', 3)
item4_list = rest.split(' ')

Split a list into two halves in Java, Given a list, we need to split into two news lists in Java. Method 1 (Naive) First create two new empty lists and assign first half element of original list and rest into second empty list. create new list and insert valuese which is returne by. // list  The SPLIT_TABLE_SUBPARTITION clause is extended similarly to allow split of a range or list subpartition into N new subpartitions. The behavior of the SQL statement with respect to local and global indexes remains unchanged. Corresponding local index partition are split into multiple partitions.

For Python3, may be you can try (As Brad Solomon mentioned link for Extended Iterable Unpacking in comments above):

(item1, item2, item3, *item4_list) = row.split(' ')

Split a String in Java, Apache's common lang package provides a StringUtils class – which contains a null-safe split() method, that splits using whitespace as the  By doing so, you can split your land into two or more residential lots, depending on the size of the property. This can turn into more profit for you as you rent out or even sell those lots. Selling subdivided land parcels often brings greater value for your property than selling the entire parcel as a whole.

Partition a List in Java, In this tutorial I will illustrate how to split a List into several sublists of a given size. Partitioning a Collection is also possible with Guava: ? Split an array into two equal Sum subarrays Given an array of integers greater than zero, find if it is possible to split it in two subarrays (without reordering the elements), such that the sum of the two subarrays is the same.

Data.List.Split, Safe Haskell, Safe List.Split module contains a wide range of strategies for splitting lists with respect to some sort of Typically chop is called with some function that will consume an initial prefix of the list and produce a value and the rest of the list. Divides up an input list into a set of sublists, according to n and m input  You can take the text in one or more cells, and split it into multiple cells using the Convert Text to Columns Wizard. Select the cell or column that contains the text you want to split. Select Data > Text to Columns. In the Convert Text to Columns Wizard, select Delimited > Next. Select the Delimiters for your data.

Programming Perl: Unmatched Power for Text Processing and Scripting, A list value may also be subscripted like a normal array. You must put the list in parentheses (real ones) to avoid ambiguity. rest) = split; my ($a, $b, %rest)  Exponential growth of money is awesome, and you should take advantage of it as soon as possible. While there are so many ways to invest your $1,000 , just make sure you do so.

Comments
  • How about (item1, item2, item3, *item4_list) = row.split(' ')
  • @student invalid syntax for both python2 and python3?
  • Not sure but for above code it worked fine.
  • Python 3 only I think, introduced in extended iterable unpacking
