A programmer can pass any type of object as an argument to a function.
Example add() function can be used for int and strings
The function's behavior of being able to add together different types is a concept called polymorphism.
Python uses dynamic typing to determine the type of objects as a program executes
In contrast to dynamic typing, many other languages like C, C++, and Java use static typing, which requires the programmer to define the type of every variable and every function parameter in a program's source code
Dynamic typing typically allows for more flexibility in terms of the code that a programmer can write, but at the expense of potentially introducing more bugs, since there is no compilation process by which types can be checked.¶
