python - 不平衡括号正则表达式

我试图在google collab中运行上面的代码，但它给出了以下错误：unbalanced parenthesis at position 4

我对 re 模块文档的理解告诉我这'\(any_expression'\)'是正确的使用方式，但我仍然得到错误。所以，我尝试替换'\(' + emot + '\)为：

  1. '(' + emot + ')'，它给出了同样的错误
  2. '[' + emot + ']'，它给出以下输出：Hello Happy_face_or_smiley-Happy_face_or_smiley Happy_face_or_smiley-Happy_face_or_smiley

正确的输出应该Hello Happy_face_smiley Happy_face_smiley是text = "Hello :-) :-)"

有人可以帮我解决问题吗？
