What must be the output of this code? Plzz answer with proper solution......

Question

a=[1,2,3]
b=a
a.append(10)
print(len(b))

Answer 1

The output is 4

a= [1,2,3] #this is a list including three items so len(a)=3
b=a# b is equal to a
a.append( 10)# this adds the item 10 to the end of list a so a= [1,2,3,10]
print (len(b))# now len(a) = 4
a=b so len(a)= len(b)= 4

Hope this helps 🙂
