A dictionary lists key-value pairs, which could also be thought of as associated values where a key matches to the associated value. Let’s look at a few examples.

| # Dictionary - mapping between values
house = {'bedrooms': 3, 'bathrooms': 2,
'city': 'Kelowna', 'price': 250000}

'Science': ['SCIENCE100', 'SCIENCE200', 'SCIENCE300']}

What if we wanted to turn the following information into a dictionary.
| Name | ID | Campus | Courses |
|---|
| Dan | 12345678 | Okanagan | DATA100, ENGL100, HIST100, CHEM100 |
This is how we would do this:
```{.python .fold-hide} student = {‘Name’ : ‘Dan’, ‘ID’ : 12345678, ‘Campus’ : ‘Okanagan’, ‘Courses’: [‘DATA100’, ‘ENGL100’, ‘HIST100’, ‘CHEM100’]} student
{‘Name’: ‘Dan’, ‘ID’: 12345678, ‘Campus’: ‘Okanagan’, ‘Courses’: [‘DATA100’, ‘ENGL100’, ‘HIST100’, ‘CHEM100’]}
```
