How to Create a Python Class and Instance

What is the code about?

What is the missing line of code to create an instance of the "patient" class and assign it to the variable "patientA" for the given Python code?

Answer:

The code provided is about creating a Python class called "patient" that includes an initialization method (__init__) to initialize the attributes of the class, such as first name, last name, and ID number. The class also has a string representation method (__str__) to display the information of the patient. The missing line of code should instantiate an object of the "patient" class and assign it to the variable "patientA".

In the given Python code:

class patient:
    def __init__(self, firstName, lastName, idNum):
        self.FirstName = firstName
        self.LastName = lastName
        self.IdNum = idNum
    def __str__(self):
        return self.FirstName + " " + self.LastName + " " + self.IdNum

patientA = patient("Pat", "Jones", "PJ23cla")

The missing piece of code to create an instance of the "patient" class and assign it to "patientA" is:

patientA = patient("Pat", "Jones", "PJ23")

After adding this line, when you run the code, it will create an instance of the "patient" class with the first name "Pat", last name "Jones", and ID number "PJ23". The output of the print statement print(patientA) will be:

Output: Pat Jones PJ23
