Write a program to demonstrate list in python
List : It is as same as arrays , it contains heterogeneous datatypes .
eg: a=[1,2,"a"]
a[0] =0
print(a)
a=[0,2,"a"]
Functions in list
| append() |
Adds an element at the end of the list |
| clear() |
Removes all the elements from the list |
| copy() |
Returns a copy of the list |
| count() |
Returns the number of elements with the specified value |
| extend() |
Add the elements of a list (or any iterable), to the end of the current list |
| index() |
Returns the index of the first element with the specified value |
| insert() |
Adds an element at the specified position |
| pop() |
Removes the element at the specified position |
| remove() |
Removes the first item with the specified value |
| reverse() |
Reverses the order of the list |
| sort() |

# Creating a List
List = []
print("empty List: ")
print(List)
|
Output
empty List:
[]
|
# Creating a List with the use of a String
List = ['GoEduHub.com']
print(List)
|
Output
['GoEduHub.com']
|
# Creating a List with the use of multiple values
List = ["Go", "Edu", "Hub",".Com"]
print(List[0]) #accesing values of list
print(List[1])
print(List[2])
print(List[3])
|
Output
Go
Edu
Hub
.Com
|
# Creating a Multi-Dimensional List By Nesting a list inside a List
List = [['Go', 'Edu'] , ['hub.com']]
print(List)
|
Output
[['Go', 'Edu'], ['hub.com']]
|
# Creating a List with the use of Numbers
List = [1, 2, 4, 4, 3, 3, 3, 6, 5]
print(List)
# Removing element using pop() method
List.pop() #removes last element
print(List)
|
Output
[1, 2, 4, 4, 3, 3, 3, 6, 5]
[1, 2, 4, 4, 3, 3, 3, 6]
|
# Print elements from beginning to a pre-defined point using Slice
SList = List[:-6]
print(SList)
# Print elements using Slice operation
Sliced_List = List[3:8]
print(Sliced_List)
# Print elements from a pre-defined point to end
SList = List[5:]
print(SList)
# Printing elements from beginning till end
SList = List[:]
print(SList)
# Creating a List with mix values
List = [1, 2, 'Go', 4, 'Edu', 6, 'Hub']
print(List)
# Printing elements in reverse using Slice operation
Sliced_List = List[::-1]
print(Sliced_List)
|
Output
[1]
[3, 3, 3, 6]
[3, 6]
[1, 2, 4, 3, 3, 3, 6]
[1, 2, 'Go', 4, 'Edu', 6, 'Hub']
['Hub', 6, 'Edu', 4, 'Go', 2, 1]
|
# Removing elements using Remove() method
List = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
print(List)
List.remove(5)
print(List)
List.remove(6)
print(List)
|
Output
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
[1, 2, 3, 4, 6, 7, 8, 9, 10, 11, 12]
[1, 2, 3, 4, 7, 8, 9, 10, 11, 12]
|
# Removing elements from List using iterator
List =[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
for i in List:
print(i)
|
Output
1
2
3
4
5
6
7
8
9
10
11
12
