# LeetCode Python
An ongoing list of LeetCode problem solutions in Python.
## NeetCode Roadmap
Refer to [NeetCode Roadmap](https://neetcode.io/roadmap).
## Get Started
Solutions for LeetCode problems are written in files under [./tests](./tests/)
respectively. This means that pytest can run test cases for a specific LeetCode
problem. But for comprehensive tests, you should copy the code to LeetCode live
editor and submit. See [LeetCode problem set](https://leetcode.com/problemset/).
There are several ways to run tests:
```sh
# Run all test cases.
pytest
# Run test cases in a given file.
pytest path/to/test_file.py
# Run a specific test case in a given file.
pytest path/to/test_file.py::test_function_name
```
