Is a Python list mutable?
Short answer. Yes. Its items can be changed.
Where does list numbering start?
At index 0.
Remember
| Items sit in numbered boxes |
| Numbering starts at 0 |
| Mutable: items can change |
One list item is wrong. Must you remake the list? No. A list is a row of boxes, numbered from zero. Mutable means a box can change. Fruits at one becomes guava. Items sit in numbered boxes. Numbering starts at zero. Items can change.
