Parameter Passing
Parameter passing is a technique used in programming that allows a function to accept multiple values, known as parameters, instead of hard-coding them into the function itself. These parameters can be passed to the function as arguments when it is called, allowing the function to operate on different sets of data with the same code.
Example:
python
def add(a, b):
return a + b
result = add(2, 3)
print(result) # Output: 5
In this example, the add function takes two parameters, a and b, which are passed to the function as arguments when it is called. The function calculates the sum of the two parameters and returns the result.
Benefits of Parameter Passing:
Code reusability: Parameters can be reused in multiple functions, reducing code duplication.
Maintainability: Changes to the function signature only affect the parameters, not the core functionality.
Flexibility: Functions can be easily extended to handle different sets of parameters.
Note:
Parameter passing can be combined with the *args keyword to pass all arguments as a single list
