For a better world

오답 1

equation = input().split("-")
_sum = 0
for i in equation:
    if "+" in i:
        result = i.split("+")
        for i in range(len(result)):
            result[i] = int(result[i])
        _sum = sum(result)

for i in equation:
    if "+" not in i:
        _sum = int(i) - _sum
print (_sum)

오답 2

equation = input().split("-")
_sum = 0
for i in equation:
    if "+" in i:
        _sum += eval(i)

for i in equation:
    if "+" not in i:
        _sum = int(i) - _sum
print (_sum)

정답

equation = input().split("-")
answer = 0
for i in equation[0].split("+"):
    answer += int(i)
for i in equation[1:]:
    for j in i.split("+"):
        answer -= int(j)
print(answer)
