# Contributor Covenant Code of Conduct
|
||||
|
||||
## Our Pledge
|
||||
|
||||
In the interest of fostering an open and welcoming environment, we as
|
||||
contributors and maintainers pledge to making participation in our project and
|
||||
our community a harassment-free experience for everyone, regardless of age, body
|
||||
size, disability, ethnicity, gender identity and expression, level of experience,
|
||||
education, socio-economic status, nationality, personal appearance, race,
|
||||
religion, or sexual identity and orientation.
|
||||
|
||||
## Our Standards
|
||||
|
||||
Examples of behavior that contributes to creating a positive environment
|
||||
include:
|
||||
|
||||
* Using welcoming and inclusive language
|
||||
* Being respectful of differing viewpoints and experiences
|
||||
* Gracefully accepting constructive criticism
|
||||
* Focusing on what is best for the community
|
||||
* Showing empathy towards other community members
|
||||
|
||||
Examples of unacceptable behavior by participants include:
|
||||
|
||||
* The use of sexualized language or imagery and unwelcome sexual attention or
|
||||
advances
|
||||
* Trolling, insulting/derogatory comments, and personal or political attacks
|
||||
* Public or private harassment
|
||||
* Publishing others' private information, such as a physical or electronic
|
||||
address, without explicit permission
|
||||
* Other conduct which could reasonably be considered inappropriate in a
|
||||
professional setting
|
||||
|
||||
## Our Responsibilities
|
||||
|
||||
Project maintainers are responsible for clarifying the standards of acceptable
|
||||
behavior and are expected to take appropriate and fair corrective action in
|
||||
response to any instances of unacceptable behavior.
|
||||
|
||||
Project maintainers have the right and responsibility to remove, edit, or
|
||||
reject comments, commits, code, wiki edits, issues, and other contributions
|
||||
that are not aligned to this Code of Conduct, or to ban temporarily or
|
||||
permanently any contributor for other behaviors that they deem inappropriate,
|
||||
threatening, offensive, or harmful.
|
||||
|
||||
## Scope
|
||||
|
||||
This Code of Conduct applies both within project spaces and in public spaces
|
||||
when an individual is representing the project or its community. Examples of
|
||||
representing a project or community include using an official project e-mail
|
||||
address, posting via an official social media account, or acting as an appointed
|
||||
representative at an online or offline event. Representation of a project may be
|
||||
further defined and clarified by project maintainers.
|
||||
|
||||
## Enforcement
|
||||
|
||||
Instances of abusive, harassing, or otherwise unacceptable behavior may be
|
||||
reported by contacting the project team at [mst10041967@gmail.com]. All
|
||||
complaints will be reviewed and investigated and will result in a response that
|
||||
is deemed necessary and appropriate to the circumstances. The project team is
|
||||
obligated to maintain confidentiality with regard to the reporter of an incident.
|
||||
Further details of specific enforcement policies may be posted separately.
|
||||
|
||||
Project maintainers who do not follow or enforce the Code of Conduct in good
|
||||
faith may face temporary or permanent repercussions as determined by other
|
||||
members of the project's leadership.

||||

### Snippet submission and Pull request guidelines
|
||||
|
||||
- **DO NOT MODIFY THE README.md FILE!** Make changes to individual snippet files. The `travis_ci` automatically builds the `README.md` file when your pull request is merged.
|
||||
- **Snippet filenames** must correspond to the title of the snippet and to the function name. For example, if your snippet is titled `### awesome_snippet` the filename should be `awesome_snippet.md` and the function name should be `awesome_snippet`.
|
||||
- Use `snake_case`, not `kebab-case` or `camelCase`.
|
||||
- Avoid capitalization of words.
|
||||
- Please follow the (PEP8)[https://www.python.org/dev/peps/pep-0008/] guidelines.
|
||||
- **Snippet titles** should have be the same as the name of the function that is present in the snippet.
|
||||
- All snippet titles must be prefixed with `###` and be at the very first line of your snippet.
|
||||
- Snippet titles must be unique (although if you cannot find a better title, just add some placeholder at the end of the filename and title and we will figure it out).
|
||||
- Follow snippet titles with an empty line.
|
||||
- **Snippet descriptions** must be short and to the point. Try to explain *what* the snippet does and *how* the snippet works and what **inbuilt** features/modules are used. Remember to include what functions you are using and why.
|
||||
- Follow snippet descriptions with an empty line.
|
||||
- **Snippets _CAN NOT_ use any external modules**. Only the modules and function inbuilt in `python 3.6` shall be used.
|
||||
- **Snippet code** must be enclosed inside ` ```python ` and ` ``` `.
|
||||
- Remember to start your snippet's code on a new line below the opening backticks.
|
||||
- You can write the code in any style you like but eventually it will be formated by our prettifier so the formatting will change. Just make sure to have consistent spacing.
|
||||
- Try to keep your snippets' code short and to the point. Use modern techniques and features. Make sure to test your code before submitting.
|
||||
- All snippets must be followed by one (more if necessary) test case after the code, in a new block enclosed inside ` ```python ` and ` ``` `. The syntax for this is `my_function('test_input') # 'test_output'`. Use multiline examples only if necessary.
|
||||
- Try to make your function name unique, so that it does not conflict with existing snippets.
|
||||
- Snippet functions do not have to handle errors in input, unless it's necessary (e.g. a mathematical function that cannot be extended to negative numbers should handle negative input appropriately).
|
||||
- Snippets should be short (usually below 20 - 30 lines). If your snippet is longer than that, you can still submit it, and we can help you shorten it or figure out ways to improve it.
|
||||
- Snippets *should* solve real-world problems, no matter how simple.
|
||||
- Snippets *should* be abstract enough to be applied to different scenarios.
|
||||
- It is not mandatory but highly appreciated if you provide **test cases** and/or performance tests.
|
||||
- You can start creating a new snippet, by using the [snippet template](snippet_template.md) to format your snippets.
|
||||
- Updating the README.md file should only be done by altering the scripts in the **scripts** folder or altering their relative static parts in the **static-parts** folder.
|
||||
- You may tag your snippet in tag_databse although it is _not_ necessary.
|
||||
- You may also run `scripts\lint.py` & `scripts\readme.py`.
|
||||
|
||||

|
||||
### Additional guidelines and conventions regarding snippets
|
||||
|
||||
- If your snippet contains argument with default parameters, explain what happens if they are omitted when calling the function and what the default case is.
|
||||
- If your snippet uses recursion, explain the base cases.
|
||||
- If your variable is not changed anywhere in the code name it in uppercase.
|
||||
- Use `camelCase` for function and variable names if they consist of more than one word.
|
||||
- Try to give meaningful names to variables. For example use `letter`, instead of `lt`. Some exceptions to convention are:
|
||||
- `arr` for lists (usually as the snippet function's argument).
|
||||
- `str` for strings.
|
||||
- `n` for a numeric value (usually as the snippet function's argument).
|
||||
- `val` or `v` for value (usually when iterating a list, mapping, sorting etc.).
|
||||
- `i` for indexes.
|
||||
- `func` for function arguments.
|
||||
- `nums` for lists of numbers.
|
||||
- Use `()` if your function takes no arguments.
|
||||
- Specify default parameters for arguments, if necessary. It is preferred to put default parameters last unless you have pretty good reason not to.
|
||||
- If your snippet's function takes variadic arguments, use `...args` (although in certain cases, it might be needed to use a different name).
|
||||
- Always use single quotes for string literals.
|
||||
- Prefer using the ternary operator (`trueResult if condition else falseResult`) instead of `if else` statements whenever possible.
|
||||
- Avoid nesting ternary operators (but you can do it if you feel like you should).
|
||||
- You should define multiple variables on the same line (e.g. `x,y = 0,1`) on the same line whenever possible.
|
||||
- Do not use trailing or leading underscores in variable names(unless it is a helper function).
|
||||
- Use lambda functions as much as possible, except when you can't.
|
||||
- Leave a single space after a comma (`,`) character.
|
||||
- Try to strike a balance between readability, brevity, and performance.
|
||||
- Never use `eval()`. Your snippet will be disqualified immediately.-->
