Examples
Creating a pyarray
let fruits = Accessing elements
| Python | pyarray | Result |
|---|---|---|
fruits |
fruits.get() |
['Banana', 'Apple', 'Orange', 'Plum', 'Grape'] |
fruits[0] |
fruits[0] |
'Banana' |
fruits[-1] |
fruits[-1] |
'Grape' |
fruits[0:-2] |
fruits['0:-2'] |
['Banana', 'Apple', 'Orange'] |
fruits[0:-1:2] |
fruits['0:-1:2'] |
['Banana', 'Orange'] |
fruits[::-1] |
fruits['::-1'] |
['Grape', 'Plum', 'Orange', 'Apple', 'Banana'] |
You can also use the .get() method as a fallback, the syntax is
obj.get(start, end, step)
