#This program gives examples about various list operations

#Syntax: list[start: end: step]

myList = [1, 2, 3, 4, 5, 6, 7, 8, 9]

#index 0 1 2 3 4 5 6 7 8

# -9 -8 -7 -6 -5 -4 -3 -2 -1

#List Slicing

print('Original List:',myList)

print('First Element:',myList[0]) #Prints the first element of the list or 0th element of the list

print('Element at 2nd Index position:',myList[2]) #Prints the 2nd element of the list

print('Elements from 0th Index to 4th Index:',myList[0: 5]) #Prints elements of the list from 0th index to 4th index. IT DOESN'T INCLUDE THE LAST INDEX

print('Element at -7th Index:',myList[-7]) #Prints the -7th or 3rd element of the list

#To append an element to a list

myList.append(10)

print('Append:',myList)

#To find the index of a particular element

print('Index of element \'6\':',myList.index(6)) #returns index of element '6'

#To sort the list

myList.sort()

#To pop last element

print('Poped Element:',myList.pop())

#To remove a particular element from the lsit BY NAME

myList.remove(6)

print('After removing \'6\':',myList)

#To insert an element at a specified Index

myList.insert(5, 6)

print('Inserting \'6\' at 5th index:',myList)

#To count number of occurences of a element in the list

print('No of Occurences of \'1\':',myList.count(1))

#To extend a list that is insert multiple elemets at once at the end of the list

myList.extend([11,0])

print('Extending list:',myList)

#To reverse a list

myList.reverse()

print('Reversed list:',myList)
