Answer:
The "def" statement is used when creating a user-defined function.
In many programming languages, including Python, the "def" statement is used to define a new function. It is followed by the name of the function, followed by parentheses that may contain input parameters, and a colon. The body of the function is indented and contains the code that defines the functionality of the function. Here's an example:
def my_function(parameter1, parameter2):
# Code block of the function
# ...
return result
In this example, "my_function" is the name of the function, and "parameter1" and "parameter2" are the input parameters that can be used within the function. The code inside the function's body defines the logic and operations to be performed, and the "return" statement is used to specify the value that the function will produce as output.
By using the "def" statement, we can create reusable and modular pieces of code that can be called multiple times with different inputs, enhancing the structure and organization of our programs.
