#Create a lists:Lists are created using a pair of brackets
list = ['a','e','i','o','u']

#Get an element in the list by index
element = list[0]
element2 = list[1]

#Add a new element after the list element
list.append('b')

#Get the element's position int the list
list.count('i')

#Clear the elements in the list
list.clear()

#Copy the list to produce a new list
newList = list.copy()

#Extension method:At the end of the list,stitch the elements of anither list
list.extend()

#Insert elements in the list
list.insert(0,'@element')

#Finds the position of the first specified element from a starting position to the ending position of the list
list = ['a','e','i','e','o','e']
list.index('e',0,5)

#Randomly delete the element in the list:Delete the last element by default
list.pop()

#Remove the specified element
list.remove('o')

#Reverse the elements in the list
list.reverse()

#Sorting of list elements:Default ASC
list.sort()
#DESC
list.sort(reverse=True)

#Remove the element in the list by index
del list[0]
list.pop(0)

#List tranversal
for element in list:
     item = element

#Get a list of random numbers
list = range(5)

#Get the length of the list
len(list)
