# Revising the Difference between Methods and Functions

## What's the difference between a function and a method?

**In python everything is an object** **A `method` gets invoked on a given Object**

```python
mylist = [1,2,3,4]
mylist.pop()
```

**A `function` does not get invoked on a given Object, it exists on it's own**

```python
maxvalue = max([1,2,3,4])
print(maxvalue)
```

A function cannot be invoked before it was defined:

```python
myname()

def myname():
	print("imtiaz")
```

## What is OOP?

* It is a way to organize the code better rather than keeping everything in one file
* Dumping everything in a single file would be very difficult to manage, so OOP allows you to keep a structure and a logical narative
* OOP allows us to re-use code that we have already written
* Break things into chunks and using multiple files
