Here is how to create a class in Python.

# Class that converts strings to uppercase
class UppercaseWord:

    def __init__(self, word):
        self.word = word
    
    def make_upper(self):
        return self.word.upper() 

# Let's instantiate the class 
cap_word1 = UppercaseWord(word='hi there') 

# Let's call the instance method
print(cap_word1.make_upper()) 

Copy & Run

HI THERE

Think of a Python class as a blueprint that creates multiple object instances which all have the same behaviors. A class is recommended to have only one responsibility. The above simple class is responsible for turning text into uppercase.

A class generally needs to have an __init__ method. When an instance of a class is created, Python executes the __init__ method of the class. Therefore, inside __init__ you may want to put the code that you want to be executed when an instance is created. In other languages, __init__ is referred to as the constructor.
