CSc 120: Python type checking

You can use the type() function as a simple way to check the type of a variable or value:

Type of x Test for type of x

integer value type(x) == int

floating-point value type(x) == float

list type(x) == list

dictionary type(x) == dict

tuple type(x) == tuple

Type of x	Test for type of x
integer value	`type(x) == int`
floating-point value	`type(x) == float`
list	`type(x) == list`
dictionary	`type(x) == dict`
tuple	`type(x) == tuple`

There are more general ways of doing this, but they are also more complex and involve concepts we have not yet covered. For now, the type() function is enough for our needs.
