
Dynamic typing – Unless otherwise specified, a variable is dynamically typed.
This means that the type is determined by the value assigned to it at evaluation
time. For example “1” is an int, “2.3” is a float, “hello” is a string, etc. A
variable that does not end in a type specifier character is dynamically typed. It
will take on the type of the expression assigned to it, and may change its type.
For example: a=4 creates a as integer, then a = “hello”, changes the variable a to
a string.
Here are some examples of types. ? is a short cut for the “print” statement. The “type()”
function returns a string that identifies the type of the expression passed in.
