Learn basic concepts, key features, and capabilities of YAML.

In this course, you will run through a comprehensive overview of the YAML data serialization language and its syntax. You will also cover the basic concepts behind this language, understand its main features, and the capabilities of YAML. 

You will kick things off by understanding what exactly YAML is. You will then move on to more concrete topics like syntax, data types, and more complex data types such as sequences, mappings, and pairs.

By the end of this course, you will have a great new skill that is transferable and highly applicable.

Introduction to YAML

# Problem
See the example YAML data below. It demonstrates the usage of a list of dictionaries and a dictionary within a dictionary.

```yaml
---
employee: 
  id: 1
  name: smith
  salary: 10000
  address: 
    city: toronto
    state: ontario
    country: canada 
    zip: A2NY1J
  commission: 
    - 
      quarter: Q1 2020
      amount: 1000
    - 
      quarter: Q2 2020
      amount: 1000
```


Now add another employee to the above document with data from the table below: 


| id | name | salary | address | commission |
|-----|--------|--------|---------|------------|
| 2|james| 10000 |city: seattle|$500 for Q1 2020| 
| | | | state: washington |  $700 for Q2 2020| 
| | | | country: united states| |
| | | | zip: 32001 | 

## Try it yourself
Before looking at the solution, please try solving it yourself in the code editor provided below. 


_Note:_ As YAML is not a programming language, the **Run** button below the code editor will only print the YAML code. You may ignore the **Run** button and simply compare manually your solution with my solution provided below.
