在 `欺骗词法作用域` 的 `eval函数接收一个字符串为参数，解析字符串生成代码并运行` 的解释中 `eval调用的str相当于在test函数作用域内部声明了一个新的变量b` 应该是声明了一个新的变量a吧，因为str是 `var a = 3`

> 防止出错所以这样写的 不影响 实际上Python的切片已经优雅的解决了这些问题，没必要重复做 ```python myStr = "123456789" # 取文本左边 len_ = 100 # 欲取出字符的数目 print(myStr[:len_]) # 123456789 # 取文本右边 len_ = 2 # 欲取出字符的数目 print(myStr[-len_:]) # 89 ```

#627 我在这个pr里尝试修复了这个问题
