<\/p>\n

A string is a sequence of characters. You can access the characters one at a time with the bracket operator. <\/span><\/p>\n

Per example, let\u2019s declare a string variable called car<\/em> containing a sequence of characters forming the word mazda6<\/em>. <\/span><\/p>\n

$\"\"$ <\/p>\n

<\/p>\n

In this example I\u2019m calling the character corresponding to the third value of index of characters. Remember that the index starts at 0, so the character 0 will be c, the character 1 a, the character 2 z and so on. <\/span><\/p>\n

Len. <\/span><\/strong><\/p>\n

The function len is able to return the numbers of characters contained in a string. Example: <\/span><\/p>\n

\u00a0<\/p>\n

$\"\"$ <\/p>\n

<\/p>\n

If you want to get the last character of a string you can try something like this: <\/span><\/p>\n

$\"\"$ <\/p>\n

<\/p>\n

Traversal. <\/span><\/strong><\/p>\n

The process of dealing one string character at time and doing something to it, is called traversal processing. <\/span><\/p>\n

Example: <\/span><\/p>\n

$\"\"$ $\"\"$ <\/p>\n

<\/p>\n

This prints individually each of the characters contained inside the car string. <\/span><\/p>\n

Slices. <\/span><\/strong><\/p>\n

Slices are segment of strings. Selecting slices of a certain strings is really easy. <\/span><\/p>\n

Example: <\/span><\/p>\n

$\"\"$ <\/p>\n

<\/p>\n

The slice that I\u2019m calling in this example is one going from the index 0 to the 4^{th<\/sup> index. Notice that using the 5 in the brackets means calling the previous character in the index. So the bracket works something like this [firstindex:lastindex+1].<\/span><\/p>\n}

Because\u2026<\/span><\/p>\n

$\"\"$ <\/p>\n

<\/p>\n

Immutability. <\/span><\/strong><\/p>\n

Strings are immutable, that meaning that you are not able to change an existing string. The best thing you can do to deal with this is creating a new string that is a variation from the original. <\/span><\/p>\n

Example, let\u2019s call a new model \u2018mazda3\u2019:<\/span><\/p>\n

$\"\"$ <\/p>\n

<\/p>\n

You can appreciate that I\u2019m calling the slice that contains the word \u2018mazda\u2019 and I\u2019m adding a \u20183\u2019 to the end, so I have a new string called new model containing the string \u2018Mazda3\u2019<\/strong><\/span><\/p>\n

Counting. <\/span><\/strong><\/p>\n

Also, you can go a little forward and count the times that a character appears in a string. Let\u2019s count how many times the \u2018a\u2019 appears in \u2018Mazda6\u2019.<\/span><\/p>\n

$\"\"$ $\"\"$ <\/p>\n

\u00a0<\/p>\n

<\/p>\n

These are somes of the things that you can do with a string. Have fun \ud83d\ude00 <\/span><\/p>\n
