method vs function python :
Difference between Python Methods vs Functions
METHODS | FUNCTIONS |
Method definition are always present inside the classes. | We don not need a class to define a functions. |
Method are associated with the object of the classes they belong to. | but Function are not associated with any objects. |
For method We cannot invoke it is just by its name | We can invoke a functions just by its name. |
Method can operate on the data of the objects they associate with it | Function operate on the data you pass to them as a argument. |
Method is dependent on the class they belong to. | Function is independent entities in a program. |
A methods requires to have ‘self’ as it first arguments. | Function do not require any ‘self’ arguments. |

- Functions is block of code that is also called by it is name.
- The functions can have different parameters and may not have any at all. If any data are passed, they are passed explicitly in order.
- It may or may not return any data.
- But Function does not deal with Classes and its instance concepts.
Four Rules for defining a function in Python
- In python block of a code of every function should begin with a colon (:) symbol
- ‘return’ function statement to return a value from the function
- We can pass any number of arguments/parameters inside the parentheses.
- Always Function block should begin with the keyword ‘def’

Some Comparison Between Method and Function in Python
- Python Method are always present inside the classes but in another case it not need a class to define a functions.
- Python method is called on an object, unlike a functions. Method can operate on the data of the objects they associate with it but in another case Function operate on the data you pass to them as a argument.
So, this was all about comparison between Method and Function in Python.
Python Class Vs Function :
Class is used to creates a user-defined data structure, which holds its own data members and member functions. A class is also called a blueprint for an object.
Some points about the Python class:
- Class is created by using keyword class.
- Property Attributes are the variables that belong to a class.
- Attributes are always public in nature and can be accessed using dot/(.) operator.
Syntax Class Definition Syntax:
class ClassName:
# Statement-1
.
.
# Statement-N
How to defining a class –
# Python program to -1
# demonstrate defining-2
# a class-3
class Cat:
pass
In the above example, class keyword indicates that you are creating a class followed by the name of the class (Cat in this case).
Summary
A Function must return a specific values but in Stored Procedure and it is optional: The procedure can returns 0 or n value. Function can have only input parameters, But procedure have both input/output parameter.
There are three different types of method in python.
1.The static method
2.The class method
3. The instance method
There is a Small difference between a Class and a Functions in python and it is just not only in the python it is there in every Oop Language. A class is basically a definition of an Objects. While a function is a small piece of code.
