>>> a = "L2-L3"
>>> removeword = ["L","-"]
>>> add = [sum(int(j) for j in i) for i in a.strip() if i not in removeword]
>>> print(add)
[2, 3] # expected 5

5What would you want if you had `"L12-L3"` ? – jpp Jun 29 '18 at 14:56

1change to `add = sum([int(j) for j in i for i in a.strip() if i not in removeword])` – Venkata Gogu Jun 29 '18 at 14:57

*"I want to do the sum in list comprehension"* No, you really don't. You want to do it outside of the comprehension, otherwise you'll end up with a list of sums. – Aran-Fey Jun 29 '18 at 14:59
