Output Questions:

[1] 
l1 = [78,89,67,45,69,42,89,]
n = l1.index(89) + l1.index(42)
print(l1.count(89))
l1.append(l1.count(100)+34)
print(l1.len())

 [2]

l1=[56,45,23,12,'ABC']

l1.extend([85,63])

l1.insert(3,99)

l1.pop()

print(l1)

l1.insert(0,101)

l1.insert(2,111)

l1.pop(2)

l1.remove('ABC')

print(l1)

[3]

l = [9,5,3,6,7,8]

l.sort()

l.reverse()

print(l)

n=sum(l)+max(l)+min(l)

print(n)

Now let’s see some error questions for QnA List methods Class 11:

Error Based Questions

[1]

l = (9,5,3,6,7,8)
print(l.len())

[2]

rno=int(input("Enter the rollno:"))

stu_name=input("Enter the name:")

fees=int(input("Enter the Fees:"))

stu_rec=list(rno,stu_name,fees)

print(stu_rec)

l.index(fees)

l.append('Manali')

l.insert(56)

[3]

l=['Jan','Feb','Mar','Apr']

l.index(2)

l.remove('Jun')

print(sort(l))

n = l.max()
