Finding the Index of an Item

Description

We can find the index of an item present in the list using the .index method.

Sage Cell

Code

A = [ 2, 3, 5, 7, 11 ]
print A.index(3)

Options

Index between i and j

We can find the index of an item (x) between indices i and j, where i <= k < j. To do so, we call the .index method and specify the parameters in this order: .index(x, i, j)

Code

A = [ 2, 3, 5, 7, 11, 2, 3, 5, 7, 11 ]
print A.index(3, 5, 9)
