Delimiters specify the boundaries between separate parts of the code or text.
Block delimiters include brackets and double quotes as well as : in python.
For example "" specifies that whatever is inside the double quotes is a string.
{} specifies whatever is in between the braces will be a dictionary.
Comma specifies that the values it is between are separate.
: specifies the end of a condtion in a control statement in python.
