numbers= [1,2,3,4] numbers.append([5,6,7,8]) print len(numbers)

  1. 4

  2. 5

  3. 8

  4. 12

  5. An exception is thrown


Correct Option: B
Explanation:

To solve this question, the user needs to know the basic syntax of Python and the behavior of the append() method.

The given code creates a list named numbers containing the integers 1, 2, 3, and 4. The append() method is then called on the numbers list, with the argument [5, 6, 7, 8]. This will add the entire list [5, 6, 7, 8] as a single element at the end of the numbers list.

So, after the append() operation, the numbers list will contain 5 elements: [1, 2, 3, 4, [5, 6, 7, 8]]. Finally, len(numbers) is called to get the length of the list, which is 5.

Therefore, the answer is:

The Answer is: B. 5

  1. 2, 4, 6

  2. 0, 1, 2, 4, 5, 6

  3. 0, 1, 4, 5

  4. 0, 1, 4, 5, 6, 7, 8, 9

  5. 1, 2, 4, 5, 6


Correct Option: C
Explanation:

Explanation: Let's go through each line of code step by step:

  1. for i in range(2): This will iterate over the values 0 and 1, because range(2) generates a sequence of numbers starting from 0 and ending at 2 (exclusive). Therefore, the output of this loop will be 0, 1.

  2. print i This will print the value of i in each iteration of the loop. In this case, it will print 0 and 1 on separate lines.

  3. for i in range(4, 6): This will iterate over the values 4 and 5, because range(4, 6) generates a sequence of numbers starting from 4 and ending at 6 (exclusive). Therefore, the output of this loop will be 4, 5.

  4. print i This will print the value of i in each iteration of the loop. In this case, it will print 4 and 5 on separate lines.

Putting it all together, the final output will be:

0
1
4
5

Option C) 0, 1, 4, 5 is the correct answer because it matches the output of the code.

foo = {1:'1', 2:'2', 3:'3'} del foo[1] foo[1] = '10' del foo[2] print len(foo)

  1. 2

  2. 7

  3. 3

  4. 4

  5. An exception is thrown


Correct Option: A

my_tuple = (1, 2, 3, 4) my_tuple.append( (5, 6, 7) ) print len(my_tuple)

  1. 1

  2. 6

  3. 4

  4. 5

  5. An exception is thrown


Correct Option: D

print type([1,2]).The output is:


Correct Option: D

names =['Amir', 'Barry', 'Chales', 'Dao'] print names [-1][-1] The output is:

  1. A

  2. r

  3. Amir

  4. Dao

  5. O


Correct Option: E

AI Explanation

To answer this question, let's break down the code and analyze each step:

The given code is:

names = ['Amir', 'Barry', 'Chales', 'Dao']
print(names[-1][-1])

The variable names is a list that contains four elements: 'Amir', 'Barry', 'Chales', and 'Dao'.

In the print statement, names[-1] is used to access the last element of the list, which is 'Dao'. Then, [-1] is used again to access the last character of the string 'Dao', which is 'o'.

Therefore, the output of the code is the character 'o'.

Option E) O is the correct answer.
