I have been recently working on code that is a calculator. I know calculations can be done in the shell but that's no fun. Anyway, I have successfully been able to separate the numbers from the equation so that I can add them together. However it outputs like so:

Numbers: 22

This happens with the equation 2+2.

What I want to happen is it to take this integer (22) and separate it into 2 and 2 then assign those to variables "num1" and "num2" so that I can add them.

I have already tried:

[int(i) for i in str(Numbers)]

But the output is in a list and I have not found anything about taking a list item and assigning it to a variable.

I have looked at this:
Splitting integer in Python?

That is what got me my output above. I have also looked at this:
Getting only element from a single-element list in Python?

But I didn't understand that and don't have a high enough reputation score to comment and ask for explanation.

This is my current code as it currently stands:

var = input("Type equation:")

if " + " in var:
 nums = str(re.findall(r'd',var))
 nums2 = nums.replace("['", "")
 nums3 = nums2.replace("', '", "")
 Numbers = nums3.replace("']", "")
 print(Numbers)

Use access through index:

num1, num2 = [int(i) for i in str(Numbers)] [0], [int(i) for i in str(Numbers)] [1]

Assign your output to two variables num1, num2

num1,num2=list(str(Numbers))
