In most cases, you may be passing more than one parameter into your program. In cases like these you need to pass the value of these parameters with respect to how they were defined in the function. Let’s see an example.

1.​ def greetUser(firstName, lastName):

2.​ purpose = input('State your purpose: ')

3.​ print(f'Hello {firstName.title()} {lastName.title()}, are these your intentions: "{purpose}" ?')

4.​

5.​

6.​ print('You have reached the umbrella corporation website')

7.​ greetUser("rebecca", "chambers") # In this function call we have the first name as the first parameter.

8.​ greetUser('chambers', 'rebecca') # In this function call we have the last name as the first parameter

Program output:

C:\Users\...\PycharmProjects\GettingStarted\venv\Scripts\Python.exe C:/Users/…/PycharmProjects/GettingStarted/MyFirstProgram.py

In rare cases, a programmer will need to pass parameters out of order. Although this is not always recommended, there are cases where it is necessary. To do that, all you have to do is add the parameter name while calling the function. Let’s take a look at the next example.

1.​ def greetUser(firstName, lastName):

2.​ purpose = input('State your purpose: ')

3.​ print(f'Hello {firstName.title()} {lastName.title()}, are these your intentions: "{purpose}" ?')

4.​

5.​

6.​ print('You have reached the umbrella corporation website')

7.​ greetUser("rebecca", "chambers") # In this function call, we have the first name as the first parameter.

8.​ greetUser('chambers', 'rebecca') # In this function call, we have the last name as the first parameter

9.​ greetUser(lastName = 'chambers', firstName='Rebecca') # We swapped the order and still were able to pass the

parameters as desired.

Program output:

C:\Users\...\PycharmProjects\GettingStarted\venv\Scripts\Python.exe C:/Users/…/PycharmProjects/GettingStarted/MyFirstProgram.py

You have reached the umbrella corporation website
