아직도 오류네요ㅠㅠ

string = input()

while string.find('-0') != -1 and (string[string.find('-0') + 1] != '-' or string[string.find('-0') + 1] != '+'):
string = string.replace('-0','-')
while string.find('+0') != -1 and (string[string.find('-0') + 1] != '-' or string[string.find('-0') + 1] != '+'):
string = string.replace('+0','+')
if string[0] == '0':
string = string[1: ]

index = string.find('-')
if index == -1:
print(eval(string))
else:
print(eval(string[ :index + 1] + string[index + 1: ].replace('+','-')))

여전히 오류네요.......흑.....
