除非Python中的语句

问题内容：

unlessPython中的语句是否等效？我不想在标签上添加一行p4port：

for line in newLines:
    if 'SU' in line or 'AU' in line or 'VU' in line or 'rf' in line  and line.find('/*') == -1:
        lineMatch = False
    for l in oldLines:
        if '@' in line and line == l and 'p4port' not in line:
            lineMatch = True
            line = line.strip('\n')
            line = line.split('@')[1]
            line = line + '<br>\n'
            labels.append(line)
    if '@' in line and not lineMatch:
        line = line.strip('\n')
        line = line.split('@')[1]
        line="<font color='black' style='background:rgb(255, 215, 0)'>"+line+"</font><br>\n"
        labels.append(line)

我收到语法错误：

   if '@' in line and not lineMatch:
   UnboundLocalError: local variable 'lineMatch' referenced before assignment

问题答案：

那“不在”呢？：

if 'p4port' not in line:
    labels.append(line)

另外我想你的代码可以修改为：

if '@' in line and line == l and 'p4port' not in line:
    lineMatch = True
    labels.append(line.strip('\n').split('@')[1] + '<br>\n')
