How to define a function in PyCharm?

The steps to define a function in PyCharm are as follows:

1. Open PyCharm and create a new Python file or open an existing Python file.
2. Choose a location in the document, then enter the function definition.
3. For example, you can input the following code to define a basic function:
4. A function named greet is defined that prints “Hello, world!” when called.
5. After defining a function, you can write the implementation code for the function. In the example above, you can add the code to be executed inside the function body.
6. Invoke the function greet(), which prints out “Hello, world!”
7. To call a function, simply follow the function name with a pair of parentheses. In the example above, you can call the greet() function by using greet().
8. call the greet() function

Here are the basic steps for defining functions in PyCharm. It’s important to use correct indentation between function definition and function call to make sure they belong to the right code block.
