leetcode's Issues

Windows 环境报错

首先是这个issue
改了以后cookies.json生成了，但是碰到下面问题：

Traceback (most recent call last):

File "leetcode_generate.py", line 248, in _generate_items_from_api
data['is_paid'] = json_data['is_paid']
KeyError: 'is_paid'
把is_paid注释掉，然后Line 143 改成

@property
    def is_lock(self):
        # return not self.is_paid and self.paid_only
        return self.paid_only

再跑就卡住不动了··好像是request连接超时··求解决下

i think leetcode changes his website again

emmmmm....
the log as follows:

ORZ

support 4 digits problem ids

since the problems has exceeded 1000, it will be nice to pad an extra zero in the front

qname = '{id}-{title}'.format(id=str(qid).zfill(4), title=qtitle)

the py script is not work?

python2.7+ubuntu

折腾了半天，终于跑通了，
环境：python2.7，ubuntu
中间出现了几个问题，记得的如下：
pip install futures；(python2.7)
在github上创建好repository,需要在linux下leetcode_generate.py代码目录先执行下git init
339行改成question = HTMLParser.HTMLParser().unescape(question) (python2.7, 需要先import HTMLParser)

第三方账号登陆

使用第三方账号登陆是需要设置初始密码才能使用

Generator does not work correctly for C++ and C# codes

In Leetcode system, they use "cpp" and "csharp" as the name of these two languages. So it is better to change line 94 and line 99 to make it work for C++ and C# codes.

update with solutions

Can someone with leetcode premium account, download the solutions

Modify the solutions count in Readme to meet the real solutions count in a certain language in setting

For example , I have solved 38 problems in leetcode, 38 in python and 2 in javascript.
When set language to javascript, the solutions in Readme should display "2"

Add a parameter: num_solved_by_language, and change the count from num_solved to num_solved_by_language

能否支持多种编程语言呢?

工具挺好用的, 先感谢作者.

但是请问能否支持多语言呢?
因为我用了多种语言(JS和JAVA)来刷leetcode,所以想爬取各种语言的代码.

python脚本优化建议

• 增加所有leetcode支持的语言。

• Readme优化，目前只要是解决过的问题都会生成一个链接。
  应该限制为：解决过的问题并且是config设置的语言才生成链接。

But sometimes  it works. i don't know why....

Nice work!

谢谢大佬！

In my local machine,exception always raise, but actually it has got the cookie. Don't know why it can't get PHPSESSID key value.

if not self.session.cookies.get('PHPSESSID'):
raise Exception('Login Error')

I use status_code to determine if login is OK and it can work normally.

run "python3 leetcode_generate.py" get back of these....

Add feature, support setting config in console

注释优化 小建议

注释符号 根据 语言来区分，比如 python可以用 # ，C/C++/C#/Swift 等 就用 //

Add annotation for different language

Now the annotation is '#', just for python

Need to add different annotation for different language

建议将Leetcode solution auto generator与solutions分成两个repo

我对auto generator很感兴趣，希望能贡献力量做进一步优化。可是solutions和generator放在一起很不方便，因为每个人solutions都不一样，如果fork之后再pull很容易造成冲突。如果将两部分分开，可以方便地修改程序同时每个人又有独立的solutions。请考虑，谢谢。

Only downloaded 6 problems for me

Hi, thanks for the generator!! It is really awesome!! However I came across the issue that I have 13 problems marked as solved on my Leetcode account. But the generator only downloaded 6 of them. Is there any specific parameter I need to adjust?

Locked problem with Leetcode Premium

Thanks for your script. I subscribed the Leetcode premium, however with this script, the locked problems still shows as locked. Can you please fix this?

Program was not exit when executing GitHub push

程序執行到 git push 時就整個停住，要用 ctrl-c 關閉，雖然最後到網頁上看是有 push 成功，但從 terminal 的畫面讓人覺得好像還沒結束。
