找不到解决程序包

Question

运行时，Azure DataBricks抛出此错误：  import re # ... class MyApp(QWidget): # ... def btn_func(self): original = self.txt_ed.toPlainText().split('\n') # https://stackoverflow.com/a/3711884 filtered = filter(lambda x: not re.match(r'^\s*$', x), original) self.txt_ed.setPlainText("\n".join(filtered))

def btn_func(self):
    lines = self.txt_ed.toPlainText().split('\n')
    word = "12"
    new_lines = [text + word for text in lines]
    self.txt_ed.setPlainText("\n".join(new_lines))
