Strings in Python can be defined using quote symbols. An example of a string definition and output below:

This will output to the terminal:

Hello World

Accesing array elements

You may access character elements of a string using the brackets symbol,
which are [ and ]. We do so by specifying the string name and the index.  

Note: Computers start counting from zero, thus  s[0] is the first character.

The example below prints the first element of a string.

To print the second character you would write:

String Slicing

You can slice the string into smaller strings. To do so you need to specify either a starting, ending index or both. Let us illustrate that in the Python shell:

>>> s = “Hello World”
>>> s[:3]
>>> s[3:]
‘lo World’
>>> s[1:3]

If no number is given, such as in s[:3] it will simply take the beginning or end of teh string. We have accessed the string as if it was an array.

If you want to output them from your program, you have to wrap them in the print command. You can store the sliced string as a new string:

There you have it! String slicing is pretty easy.

    “teh string”
    I laughed when I saw that XD
    So substrings are just specified like parts of a list?
    Can you do it with lists too, like
    list = [5,6,7,8,10]

      Yes, they are specified like parts. It works with lists too. Both of them can be manipulated using the same style.
