python 中

data = r'test TES(1+2) MAX(3+2) AX(4+5)'

x=r'([^()]*)'

x=r'[A-Z]+' + x

b=re.findall(x,data)

print(b)

要求输出 ['TES(1+2)','AX(4+5)']

排除掉前缀为 MAX 的字符串,我尝试前面加(?!MAX) 但不成功

@xiangyuecn 谢谢~!也可以这么写:
x=r'\([^()]*\)'

x=r'\b(?!MAX)[A-Z]+?' + x

酱紫也行：[A-Z]+(?<!MAX)\(.*?\)

\s((?!MAX)[A-Z]+?\(.+?\))

\s 表示大写字母前面的空格，(?!MAX)表示不匹配这个，[A-Z]+?表示匹配大写字母，\(.+?\)括号和里面的内容
