# Python List Methods Tutorial: Python List Count()

The count() method returns the number of occurrences of an element in a list.
In simple terms, count() method counts how many times an element has occurred in a list and returns it.

The syntax of count() method is:

``````list.count(element)
``````

## count() Parameters

The count() method takes a single argument:

• element - element whose count is to be found.

## Return value from count()

The count() method returns the number of occurrences of an element in a list.

### Example 1: Count the occurrence of an element in the list

``````# vowels list
vowels = ['a', 'e', 'i', 'o', 'i', 'u']

# count element 'i'
count = vowels.count('i')

# print count
print('The count of i is:', count)

# count element 'p'
count = vowels.count('p')

# print count
print('The count of p is:', count)
``````

When you run the program, the output will be:

``````The count of i is: 2
The count of p is: 0
``````

### Example 2: Count the occurrence of tuple and list inside the list

``````# random list
random = ['a', ('a', 'b'), ('a', 'b'), [3, 4]]

# count element ('a', 'b')
count = random.count(('a', 'b'))

# print count
print("The count of ('a', 'b') is:", count)

# count element [3, 4]
count = random.count([3, 4])

# print count
print("The count of [3, 4] is:", count)
``````

When you run the program, the output will be:

``````The count of ('a', 'b') is: 2
The count of [3, 4] is: 1
``````

## Lambda, Map, Filter functions in python

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.

Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is

Syntax: x = lambda arguments : expression

Now i will show you some python lambda function examples:

## The anatomy of Python Lists

### An easy guide to summarize the most common methods and operations regarding list manipulation in Python.

Python lists are a built-in type of data used to store items of any data type such as strings, integers, booleans, or any sort of objects, into a single variable.

Lists are created by enclosing one or multiple arbitrary comma-separated objects between square brackets.

### Access values by index

## How To Compare Tesla and Ford Company By Using Magic Methods in Python

Magic Methods are the special methods which gives us the ability to access built in syntactical features such as ‘<’, ‘>’, ‘==’, ‘+’ etc…

You must have worked with such methods without knowing them to be as magic methods. Magic methods can be identified with their names which start with __ and ends with __ like init, call, str etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).

Now there are a number of such special methods, which you might have come across too, in Python. We will just be taking an example of a few of them to understand how they work and how we can use them.

### 1. init

``````class AnyClass:
def __init__():
print("Init called on its own")
obj = AnyClass()
``````

The first example is _init, _and as the name suggests, it is used for initializing objects. Init method is called on its own, ie. whenever an object is created for the class, the init method is called on its own.

The output of the above code will be given below. Note how we did not call the init method and it got invoked as we created an object for class AnyClass.

``````Init called on its own
``````

Let’s move to some other example, add gives us the ability to access the built in syntax feature of the character +. Let’s see how,

``````class AnyClass:
def __init__(self, var):
self.some_var = var
return self.some_var + other_obj.some_var
obj1 = AnyClass(5)
obj2 = AnyClass(6)
obj1 + obj2
``````
