python list heterogeneous items and python len() function

 The list data structure is very flexible It has many unique inbuilt functionalities

Different methods of creating a list, adding, modifying, and deleting elements in the list. Also, learn how to iterate the list and access the elements in the list in detail.

The following are the properties of a list.

Mutable: The elements of the list can be modified. We can add or remove items to the list after it has been created.

Ordered: The items in the lists are ordered.

Heterogeneous: The list can contain different kinds of elements.i.e; they can contain elements of string, integer, boolean, or any type.

Duplicates: The list can contain duplicates i.e., lists can have two items with the same values.

Ex:

mylist=[89,44,55,22,90]

print(mylist)

print(type(mylist))

output:89,44,55,22,90

#Using list() constructor: In general, the constructor of a class has its class name.

mylist=list([34,55,66,77,23])

print(mylist)

ouput:34,55,66,77,23

# list heterogeneous items

mylist = [1.0, 'ram', 30,50,77,'krishna']

print(mylist)

output:1.0, 'ram', 30,50,77,'krishna'

#list functions

#list length function-In order to find the number of items present in a list, we can use the len() function.

mylist = [31, 42, 23,98]

print(len(mylist))

output:31,42,23,98
