Python program to implement list operations (Nested, lenght, concat)

a=[3,4,5,6,8,1,2]
b=[1,2,3,4,5,6,7]
c=['batman']
print(a)
print(b)
print(c)
print (len(a))
print(a+b)
for n in a:
  print (2*n)
print (a[2])
print(c*4)
print(5 in a)
print(a)
print(a[-2])
print(a[0:2])

Python program to implement list methods (Add, Append, Extend, Delete)

a=[2,4,6,8]
print(a)
a[0]=1
print(a)
a.append(7)
print(a)
a.extend([5,6,7])
print(a)
del a[2]
print(a)
