how to call a function in python
Answers
⭕HØLA DEAR⭕
✏When you call a function, you are basically just telling the program to execute that function. So if you had a function that added 2 no. such as:
\begin{lgathered}def \: add \: (a \: b) \\ return \: a + b\end{lgathered}
defadd(ab)
returna+b
✏You would call the function like this:
add(3 + 5)add(3+5)
✏Which would return 8.You can put any 2 numbers in the parentheses in this case. You can also call a function like this:
answer = add(4 + 7)answer=add(4+7)
✏Which would set the variable answer equal to 11 in this case.

Functions are common to all programming languages, and it can be defined as a block of re-usable code to perform specific tasks. But defining functions in Python means knowing both types first: built-in and user-defined. Built-in functions are usually a part of Python packages and libraries, whereas user-defined functions are written by the developers to meet certain requirements. In Python, all functions are treated as objects, so it is more flexible compared to other high-level languages.
Importance of user-defined functions in Python
Importance of user-defined functions in PythonIn general, developers can write user-defined functions or it can be borrowed as a third-party library. This also means your own user-defined functions can also be a third-party library for other users. User-defined functions have certain advantages depending when and how they are used. Let ‘s have a look at the following points.

Let ‘s have a look at the following points.User-defined functions are reusable code blocks; they only need to be written once, then they can be used multiple times. They can even be used in other applications, too.These functions are very useful, from writing common utilities to specific business logic. These functions can also be modified per requirement.The code is usually well organized, easy to maintain, and developer-friendly. Which means it can support the modular design approach
