Defining a new function does not make the function run. To do that we need a function call. Function calls contain the name of the function being executed followed by a list of values, called arguments, which are assigned to the parameters in the function definition.
What does def stand for Python?

When using a function what is the first thing you must do?
To create a function, we must first declare it and give it a name, the same way we’d create any variable, and then we follow it by a function definition: var sayHello = function() { }; We could put any code inside that function – one statement, multiple statements – depends on what we want to do.
What is the purpose of calling a function?
A function is a set of code that performs a specific task and can be used whenever needed just by calling it. While using multiple function calls or recursion, the concept of a function call is very necessary to be known, for better understanding of the code.
What is __ init __ in Python?
The __init__ method is the Python equivalent of the C++ constructor in an object-oriented approach. The __init__ function is called every time an object is created from a class. The __init__ method lets the class initialize the object’s attributes and serves no other purpose. It is only used within classes.
Why do we use == in Python?
The == operator helps us compare the equality of objects. The is operator helps us check whether different variables point towards a similar object in the memory. We use the == operator in Python when the values of both the operands are very much equal. Thus, the condition would become true here.
How do you put parentheses in a string in Python?
The standard way to format strings in Python is to use a combination of curly braces and standard parenthesis, by inserting empty curly braces in the place where you want to add something to a string.

To solve this error, add parentheses around any statements you want to print to the console. This is because, in Python 3, print is not a statement.
What is type () function in Python?
Python type() is a built-in function that returns the type of the objects/data elements stored in any data type or returns a new type object depending on the arguments passed to the function. The Python type() function prints what type of data structures are used to store the data elements in a program.
