    使用正则表达式。

    例子：

    import re

string = 'Free space "974.62MB" in the Storage[/home/doom] has dropped below the recommended threshold "5GB", it is recommended to free up space in the storage as soon as possible'

# Извлечение данных в кавычках
quoted_data = re.findall(r'"([^"]*)"', string)
# Извлечение данных в скобках
bracketed_data = re.findall(r'\[(.*?)\]', string)

print("Quoted data:", quoted_data)
print("Bracketed data:", bracketed_data)
