Casting a string containing comma separated values into an integer

given a string :

>>> string = "0,1,2"
>>> print string
0,1,2

how can I split the string and cast the values into integers, putting them into a list?

Using split,map and int map produces a list by applying the given function(int as of now) on the given iterable

Code:

string = "0,1,2"
lst = string.split(",")
int_lst  = map(int, lst)
print int_lst

Output:

[0, 1, 2]

You can use map to map the cast to int to every element of the list you create when splitting it.

>>> string = "0,1,2"
>>> print map(int, string.split(','))
[0, 1, 2]

mystring = "0,1,2"
mylist = [int(i) for i in mystring.split(",")]
print mylist

Output:

[1,2,3]

Just use split, int, and a simple list comprehension.

In [1]: s = "0,1,2"

In [2]: t = s.split(",")

In [3]: t
Out[3]: ['0', '1', '2']

In [4]: v = [int(u) for u in t]

In [5]: v
Out[5]: [0, 1, 2]

In one go:

In [7]: v = [int(u) for u in s.split(",")]; v
Out[7]: [0, 1, 2]
