Pylint部分：

1. 补充module docstring，即文档顶部的简要说明 （我做的说明很简陋，只是为了通过pylint的检查而为之）
2. 优化了if-else-return，即删除了不必要的elif或else
3. 拆分了所有在同一行的模块引用（不同模块的引用需要放在不同行，以便理解和阅读）
4. 删除了部分没有被使用的引用（有的引用在文件A中被使用了，但import却写在了文件B，且文件B没有使用这些引用，而文件A引用了文件B，导致文件B的所有引用也被A引用，这似乎并不合理）
5. 修改了引用的顺序（os、random等系统引用应放在自定义模块引用的上方）
6. 修改了过长的代码，注释除外（每行限制在100个字符以内）
7. 优化了条件判断的判断符号：
is和is not 用于判断两个变量是否指向同一个位置
== 和 !=用于比较两个变量
8. 为每个py文件添加了"last new line"，删除了多余的尾部空行

Pylint提示了但是没有进行的操作：
1. 将字符串改为f-string的格式
因为f-string需要python3.6以上的版本，为了防止出现版本问题，故不做修改
2. 将所有函数内的return内容改为一致的类型
因为原有的代码逻辑已经确定，修改return的类型会导致方法的无法使用，故不做修改
3. 将标识符的格式改为"snake_case naming style"
标识符的修改内容过于庞大，且可能出现程序不可预见的错误，在pylint中重要等级为0，故不做修改
JSLint Part:
1. 提高代码的可读性：将部分超过80个字符的代码行拆解开（由于文字注释的存在，很多语句仅注释就超过了80个字符，此类型的语句行不做修改）
2. 用===与！==代替==与！=的判断
3. 将i++改为i+=1
4. 分离for循环中的let与var到其他行中，以适应JSLint在循环语句中对var和let的偏好
5. 给三元表达式外围添加圆括号，避免出现优先级的问题
6. 将正则表达式修改为JSLint要求的多行模式

疑问：
形如：
for (let i = 0; i < list.length; i+=1) {
的语句，JSLint报错： [JSLint was unable to finish] Unexpected 'let'.
但是网上搜索到的结果是ES6是支持let的使用的，暂且不做修改。

-## End-to-end testing
-
-We use the Selenium test framework to test our app.
-
-In order to run the test, first we need to download a webdriver executable.
-
-Microsoft Edge's webdriver can be downloaded from [microsoft-edge-tools-webdriver](https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/). Make sure the version we download matches the version of the web browser installed on our laptop.
-
-After extracting the downloaded zip file (e.g., edgedriver_win64.zip), rename msedgedriver.exe to MicrosoftWebDriver.exe.
-
-Add MicrosoftWebDriver.exe's path to system's PATH variable.
-
-Install the following dependencies too:
-
-- pip install -U selenium==3.141.0
-- pip install -U urllib3==1.26.2
-
-Run English Pal first, then run the test using pytest as follows: pytest --html=pytest_report.html test_add_word.py
-
-The above command will generate a HTML report file pytest_report.html after finishing executing test_add_word.py.  Note: you need to install pytest-html package first: pip install pytest-html.
-
-You may also want to use [webdriver-manager](https://pypi.org/project/webdriver-manager/) from PyPI, so that you can avoid tediously installing a web driver executable manually.  However, my experience shows that webdriver-manager is too slow.  For example, it took me 16 minutes to run 9 tests, while with the pre-installed web driver executable, it took less than 2 minutes.
