Python newbie array - list conversion

Question

I have an array like this type ["1" "2" "3"], how can I change this into a list [1, 2, 3] Could some one please help me regarding this?

Answer 1

Here's one way:

myList = [ "1", "2", "3" ]
myList = [ int(i) for i in myList ]

Answer 2

Both ["1", "2", "3"] and [1, 2, 3] are lists. The former is just a list of strings, whereas the latter is a list of integers. Call int on every element to convert it to an integer, like this:

str_list = ["1", "2", "3"]
int_list = [int(e) for e in str_list]
# or ...
int_list = map(int, str_list)

Answer 3

If your array is really ["1" "2" "3"], it will be concatenated into a single string like such ["123"] so you'll need split the string like so:

newList = []
for n in xrange(len(oldList[0])):
    newList.append(int(oldList[0][n]))
