4 If you need to see the type of a variable, you can use the type class, which can return the type of the variable or create a new type.
5 Python has 3 ways to represent string types, namely single quotes, double quotes, and triple quotes. Single and double quotes have the same effect. Python programmers prefer to use single quotes, and C/Java programmers are used to using double quotes for strings. Characters such as single quotation marks, double quotation marks, or newlines can be entered in triple quotation marks.
