Python program for various list operations

Python List activities example: Here, we will find out about the different list tasks like getting to components, printing components, switching components, embeddings, and so forth in Python.

Here, we are executing a python program for different list activities, the following tasks are being acted in the list,

1. Pronouncing an integer list
2. Printing the total list
3. Printing the principal component of the list
4. Printing ith component of the list
5. Printing components inside the given files
6. Printing a particular component utilizing the negative ordering
7. Attaching a component to the list
8. Finding the file of a particular component in the list
9. Arranging the list components
10. Popping a component from the list
11. Expelling indicated component from the list
12. Embeddings a component at indicated file
13. Broadening the list, for example, embed set of component (list) in the list
14. Turning around list components

Python code for different list activity:

# Python code for various list operation

# declaring a list of integers
iList = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100]

# List slicing operations
# printing the complete list
print('iList: ',iList)
# printing first element 
print('first element: ',iList[0]) 
# printing fourth element 
print('fourth element: ',iList[3]) 
# printing list elements from 0th index to 4th index
print('iList elements from 0 to 4 index:',iList[0: 5]) 
# printing list -7th or 3rd element from the list
print('3rd or -7th element:',iList[-7]) 


# appending an element to the list
iList.append(111)
print('iList after append():',iList)

# finding index of a specified element 
print('index of \'80\': ',iList.index(80))

# sorting the elements of iLIst
iList.sort()
print('after sorting: ', iList);

# popping an element
print('Popped elements is: ',iList.pop())
print('after pop(): ', iList);

# removing specified element
iList.remove(80)
print('after removing \'80\': ',iList)

# inserting an element at specified index 
# inserting 100 at 2nd index 
iList.insert(2, 100)
print('after insert: ', iList)

# counting occurances of a specified element
print('number of occurences of \'100\': ', iList.count(100))

# extending elements i.e. inserting a list to the list
iList.extend([11, 22, 33])
print('after extending:', iList)

#reversing the list
iList.reverse()
print('after reversing:', iList)

Output:

iList:  [10, 20, 30, 40, 50, 60, 70, 80, 90, 100]  
first element:  10
fourth element:  40  
iList elements from 0 to 4 index: [10, 20, 30, 40, 50]
3rd or -7th element: 40 
iList after append(): [10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 111] 
index of '80':  7 
after sorting:  [10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 111] 
Popped elements is:  111
after pop():  [10, 20, 30, 40, 50, 60, 70, 80, 90, 100]  
after removing '80':  [10, 20, 30, 40, 50, 60, 70, 90, 100] 
after insert:  [10, 20, 100, 30, 40, 50, 60, 70, 90, 100]
number of occurences of '100':  2
after extending: [10, 20, 100, 30, 40, 50, 60, 70, 90, 100, 11, 22, 33] 
after reversing: [33, 22, 11, 100, 90, 70, 60, 50, 40, 30, 100, 20, 10]
