### Question :

How to split a string of space separated numbers into integers?

I have a string `"42 0"` (for example) and need to get an array of the two integers. Can I do a `.split` on a space?

``````>>> "42 0".split()  # or .split(" ")
['42', '0']
``````

Note that `str.split(" ")` is identical in this case, but would behave differently if there were more than one space in a row. As well, `.split()` splits on all whitespace, not just spaces.

Using `map` usually looks cleaner than using list comprehensions when you want to convert the items of iterables to built-ins like `int`, `float`, `str`, etc. In Python 2:

``````>>> map(int, "42 0".split())
[42, 0]
``````

In Python 3, `map` will return a lazy object. You can get it into a list with `list()`:

``````>>> map(int, "42 0".split())
<map object at 0x7f92e07f8940>
>>> list(map(int, "42 0".split()))
[42, 0]
``````

``````text = "42 0"
nums = [int(n) for n in text.split()]
``````

``````l = (int(x) for x in s.split())
``````

If you are sure there are always two integers you could also do:

``````a,b = (int(x) for x in s.split())
``````

or if you plan on modifying the array after

``````l = [int(x) for x in s.split()]
``````

This should work:

``````[ int(x) for x in "40 1".split(" ") ]
``````

Of course you can call `split`, but it will return strings, not integers. Do

``````>>> x, y = "42 0".split()
>>> [int(x), int(y)]
[42, 0]
``````

or

``````[int(x) for x in "42 0".split()]
``````

Here is my answer for python 3.

``````some_string = "2 3 8 61 "

list(map(int, some_string.strip().split()))
``````

Other answers already show that you can use split() to get the values into a list. If you were asking about Python’s arrays, here is one solution:

``````import array
s = '42 0'
a = array.array('i')
for n in s.split():
a.append(int(n))
``````

Edit: A more concise solution:

``````import array
s = '42 0'
a = array.array('i', (int(t) for t in s.split()))
``````

``````In : [int(i) for i in '1 2 3a'.split() if i.isdigit()]
