Research direction
Open 「07.字符串和常用数据结构.md」 and locate the 「生成式和生成器」 examples. Run the example through print(sys.getsizeof(f)) and add the missing sys import at the beginning; done means the example runs without the reported NameError.

Description
「07.字符串和常用数据结构.md」中「生成式和生成器」 的示例代码用到了 sys 模块的函数，所以程序执行到 print(sys.getsizeof(f)) 这一步时会报如下错误：
Exception has occurred: NameError
name 'sys' is not defined
需要在开头加上 import sys 或者 from sys import getsizeof
今天7号刚好学到第7天的教程，希望能早点学完~
