I have many data points in a dictionary list that is saved as:

{'Canada': ['10.625', '80.743'], 'Sao Tome and Principe': ['32.399', '63.935']}

I need to calculate the Euclidean distance between them by using the two numbers in each data point by using the formula:

```
sqrt{[x_j-x_i]**2 + [y_j-y_i]**2}

```

How can I so this with dictionaries? I can't figure out or find any answers on how to use the [ ] part of the {'Canada': ['10.625', '80.743']}

I need to write a function that calculates the distance between two data point coordinates in a dictionary, but I don't know where to begin.

```
def distance():
   # compute distance where two data point in a dictionary is used
   # data points e.g.: {'Canada': ['10.625', '80.743'], 'Sao Tome and Principe': ['32.399', '63.935']}
   distance = result(sqrt{[10.625,32.399]**2 + [80.743,63.935]**2})

```
