Slicing
Good, now you know how to extract a single element from a string. But what if you need to get multiple sequential elements at once? Indeed, you can extract these elements one by one, but it's a bit irrational, isn't it?
Surely it is. To get multiple elements at once, you can use slicing. To do so, pass the starting and ending indices within square brackets divided by the colon :
sign. Note that the second index will not be included. For example, if you use [1:5]
, you will get all the elements with indices from 1 to 4. You can look at the example below.
As you can see, the last index is greater than the index of the last element by 1.
You are given the string "Python"
stored within the language
variable. You need to get the following fragments using slicing: tho
, on
. For your convenience, the indices for this string are shown below.
