Code:
#Access List Element
L = [['COMPUTER', 'AIML'], ['Mechanical', 'MECHATRONICS'], 'CIVIL', 'ROBOTICS']
print("Length: ",len(L))

print(L[1])
print(L[1:3])
print(L[-2])
print(L[-3:3])
print(L[1:-4])
print(L[-3:-4])
print(L[:])
print(L[1][1])
Output:
Length: 4

Code:
# Sum of element
L = [11, 2, 4, 20]
print("Sum of all elements: ", sum(L))
Output:
Sum of all elements: 37

Code:
# Multipilication of all elements
L = [11, 2, 4, 20]
m=1
for i in L:
m *= i
print("Multipilication of all elements: ", m)
Output:
Multipilication of all elements: 1760

Code:
# Largest and smallest number
L = [11, 2, 4, 20]
print("Largest no: ", max(L))
print("Smallest no: ", min(L))

Output:
Largest no: 20
Smallest no: 2

Code:
# Reverse
L = [11, 2, 4, 20]
L.reverse()
print(L)
Output:
[20, 4, 2, 11]

Code:
# Delete all even elements from a given list
L = [1, 3, 2, 4, 5, 6]
k=0
for i in range(len(L)):
if L[k] % 2 == 0:
del(L[k])
continue
k += 1
print(L)
Output:
[1, 3, 5]

Code:
# Delete common elements
L1 = [10, 20, 30]
L2 = [20, 10, 50, 50]

for i in L1:
if i in L2:
print(i)
Output:
10
20

Code:
# Methods of list class
L = [10, 20, 30]

#append(): add single element at last position


L.append('OOP')
print(L)
#extend(): add multiple elements at last position
L.extend("PWP")
print(L)
L.extend((1, 2))
print(L)

#count(): will return count of specific element in a list


L1 = [1, 2, 3, 1, 2, 3, 4, 1]
print(L1.count(1))

#insert(): add single element at specific position


L1.insert(3, 'SERVER')
print(L1)

#remove(): delete single element from list by using element value


L2 = ['Mange','Grapes','potato','Watermelon']
L2.remove('potato')
print(L2)

# pop(): delete single element from list by using element position


print("Deleted element: ", L2.pop(1))
print(L2)

e1 = L2.pop() # last element will be deleted


print(e1)
print(L2)
Output:
[10, 20, 30, 'OOP']
