define a class

class fruit():
    def __init__(self, size, color):
        self.color = color
        self.size = size
    def grow(self, increment):
        self.size = self.size + increment
        return(self.size)

create an object of that class

apple = fruit(10, 'red')

access attributes

apple.size
10

apple.color
'red'

use methods

apple.grow(10)
20

Thanks @atlasgcx . To make your code more readable, try formatting it like this:

Input:

 ```python
class fruit():
    def __ init __(self, size, color):
        self.color = color
        self.size = size
    def grow(self, increment):
        self.size = self.size + increment
        return(self.size)
```

Result:

class fruit():
    def __ init __(self, size, color):
        self.color = color
        self.size = size
    def grow(self, increment):
        self.size = self.size + increment
        return(self.size)
