[Type A] Working with Functions – Chapter 3 Sumita Arora

4. What are arguments? What are parameters? How are these two terms different yet related? Give an example.

Solution:

• Parameters: Parameters are placeholders in the function definition. They act as variables that represent the data that the function expects to receive when it is called. Parameters are defined within the parentheses of the function header.
• Arguments: Arguments are the actual values that are passed to the function when it is called. These values are substituted for the parameters defined in the function declaration.

Relation: Parameters and arguments are directly related because arguments are used to initialize parameters. When a function is called, the values passed as arguments are assigned to the corresponding parameters defined in the function header.

# Function definition with a parameter
def greet(name):  # 'name' is a parameter
    print("Hello,", name)

# Function call with an argument
greet("Mohan")  # "Mohan" is an argument

In this example, "Mohan" is the argument passed to the greet() function, and it initializes the name parameter within the function.

In short, arguments are the values passed to a function during its call, while parameters are the variables used to define those values in the function definition.
