Series from
| Source | Index from |
|---|---|
| List | 0, 1, 2 |
| Dictionary | the keys |
| Scalar | you give it |
| NumPy array | 0, 1, 2 |
Remember
| Dictionary keys become the index |
| A scalar repeats for every label |
How many ways to create a Series? Four. Four sources. A list gets index zero, one, two. A dictionary uses its keys. A scalar needs your index. An array acts like a list. Two rules. Keys become the index. A scalar repeats per label.
