Python List Test – 2

1. Suppose list1 is [1, 3, 2], What is list1 * 2?

2. Suppose list1 is [3, 4, 5, 20, 5, 25, 1, 3], what is list1.count(5)?

3. To remove string "hello" from list1, we use which command?

4. What will be the output of the following Python code?

7. What will be the output of the following Python code?

names1 = ['Amir', 'Bear', 'Charlton', 'Daman']
names2 = names1
names3 = names1[:]

names2[0] = 'Alice'
names3[1] = 'Bob'

sum = 0
for ls in (names1, names2, names3):
    if ls[0] == 'Alice':
        sum += 1
    if ls[1] == 'Bob':
        sum += 10

print sum
