How to call functions in Python, in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

What is the function function? The function of function

A function is a small method or Mini Program that can perform some specific functions. There are many built-in functions in Python, and of course, as you learn more, you can also learn to create functions that are useful to you. Simply understand the concept of the function, that is, you write some statements, in order to facilitate the use of these statements, put these statements together, give it a name. As long as you call this name when you use it, you can realize the function of statement group.

Before using a function, we use * * when we want to calculate the power of a number. The method is as follows:

> 2.

8 # here is the return value of the python function

Now that you know the function, you can use the built-in function pow to calculate the multiplier:

> pow (2Pol. 3)

eight

What is the python built-in function and how to call the function

Some of the functions included in the python system are called built-in functions, such as dir (), type (), and so on, which do not need to be written by ourselves. There is also a third-party function, which is some functions compiled by other programmers and shared with you. Both of the functions mentioned above can be used directly. Finally, we make up some functions that are convenient for us to work and study, which are called custom functions.

Although the method of function call is not explained, it has been used in the previous case. Pow () is a built-in function that comes with the system. As long as you use the function name correctly and write the parameters, you can use it.

The method of defining function function

The defstatement is required to define the function. The syntax format of the defined function is shown in the figure:

The editor reminds you of a few things to pay attention to when defining a function:

1. Start with def, which represents a defined function.

2. Type a space between the def and the function name

3. After that, there is the name of the function, which is given by the user himself, so it is convenient for him to use.

4. The function name is followed by parentheses (), which means that the function is defined, and parameters can be added to it.

5. be sure to add a colon after the parentheses (): this is very important, don't forget it.

6. The code block is made up of statements and should be indented.

7. The function must have a return value of return

The following is a complete example of the function for your reference:
