Defining a Function:
A function is a block of code that contains a set of instructions that perform a specific task. It is a reusable piece of code that can be called multiple times with the same inputs, producing the same output.
Example:
python
def sum(a, b):
return a + b
This function takes two arguments, a and b, and returns the sum of these two numbers. It can be called like this:
python
print(sum(5, 10)) # Output: 15
Calling a Function:
When you want to use a function, you call it by passing the function's name and any necessary arguments to its parentheses. The function then executes its instructions and returns the final output.
Example:
python
area = function(length, width)
This function takes two arguments, length and width, and returns the area of a rectangle. It can be called like this:
python
print(area(5, 10)) # Output: 50
Key Points:
A function can perform multiple tasks.
It has a specific name and set of instructions.
You call a function by passing its name and arguments to its parentheses.
Functions can be reused and called multiple times with the same inputs
