Question
create a class Greet that reads in from the console a string, and then outputs a greeting Hi ...!, where the name replaces the elipses. e.g. If the input is Hugh then your output should be Hi Hugh!.
Solution
Here is a simple implementation of the class in Python:
class Greet:
def __init__(self):
self.name = input("Please enter your name: ")
def say_hello(self):
print(f"Hi {self.name}!")
Here's how you can use this class:
g = Greet() # Create an instance of the Greet class
g.say_hello() # Call the say_hello method
When you run this code, it will prompt you to enter a name. After you enter a name (for example, "Hugh"), it will print "Hi Hugh!".
Here's a step-by-step explanation of how this code works:
- The
Greetclass is defined with two methods:__init__andsay_hello. - The
__init__method is a special method that gets called when you create a new instance of the class. In this case, it prompts the user to enter a name and stores it in thenameattribute of the class. - The
say_hellomethod prints a greeting that includes the name that was entered. - After the class is defined, an instance of the class is created with the line
g = Greet(). This calls the__init__method and prompts the user to enter a name. - Finally, the
say_hellomethod is called with the lineg.say_hello(). This prints the greeting.
