Python Objects Source

We can use the built-in ``` isinstance() ``` method to check if an object is an instance of a specific Class. The syntax for this method is ```isinstance(object, class)```. If the object is an instance of that class, the method will return ```True```, if not, it will return ```False```.
Example-
```python
class Employee:
    id = 7

emp1 = Employee()

print(isinstance(emp1, Employee)) #Prints True

print(isinstance(1, int)) #Prints True 

```

Check if an Object is an instance of a specific Class

To create objects we instantiate the class by calling the class name and assigning it to the variable. 
```python
obj = ClassName()
```
To access the object attributes and methods we can use the dot operator.
```python
print( obj.items )
print( obj.findMaximum() )
```

In Python, classes may be defined using the following syntax:
```python
class ClassName:

    def __init__(self, dataList, dataString):
        self.items = dataList
        self.descriptor = dataString

    def findMaximum(self):
        return max(self.items)

    def __str__(self):
        return self.descriptor
```
