Convert a number to a list of integers

Question

How do I write the magic function below?

>>> num = 123
>>> lst = magic(num)
>>>
>>> print lst, type(lst)
[1, 2, 3], <type 'list'>

Answer 1

You mean this?

num = 1234
lst = [int(i) for i in str(num)]

Answer 2

You could do this:

>>> num = 123
>>> lst = map(int, str(num))
>>> lst, type(lst)
([1, 2, 3], <type 'list'>)

Answer 3

a = 123456
b = str(a)
c = []

for digit in b:
    c.append (int(digit))

print c

Answer 4

Don't use the word list as variable name! It is a name of python built in data type.

Also, please clarify your question. If you are looking for a way to create a one-member list, do the following:

a = 123
my_list = [a]

and "pythonizing" Cannonade's answer:

a = 123
my_list = [int(d) for d in str(a)]

Answer 5

magic = lambda num: map(int, str(num))

then just do magic(12345) or magic(someInt) or whatever
