How to make a list without quotes from string? python3

Question

I want to make a program in which i input a string then make it into list and then use list.count. To do this i need list without colons.

a=("44, 4, 5, 6, 7, 8 ")
a=[a]
print(a)
-> ['44, 4, 5, 6, 7, 8 ']

but i want this:

[44, 4, 5, 6, 7, 8]

i tried this:

b=map(int, a)
print(b)

but then get this ->

<map object at 0x00537810>

and don't know what to do next

Answer 1

It's even easier than that:

>>> a=("44, 4, 5, 6, 7, 8 ")
>>> my_list = [int(s) for s in a.split(", ")]
>>> my_list
[44, 4, 5, 6, 7, 8]
>>>
