List,Tuples,Dictionary

Elements of a tuple can be accessed in the same way as list or string using

• Indexing

• Slicing

• Both indexing and slicing

• None of the above

init_tuple = ('Python') * 3

print(type(init_tuple))

• A. <class ‘tuple’>
  

• B. <class ‘str’>
  

• C. <class ‘list’>
  

• D. <class ‘function’>

What is the output of the below Python code?

a = {(1,2):1,(2,3):2}

print(a[1,2])

• A. Key Error
  

• B. {(2,3):2}

• C.  1

• D. {(1,2):1}

The code below has a Python function writing to a dictionary. What will it print in the end?

• A. 1
  

• B. 2
  

• C. 3
  

• D. 4

What will be the output of the Python code given below?

dict = {'c': 97, 'a': 96, 'b': 98}

for _ in sorted(dict):

print (dict[_])

• A. 96 98 97
  

• B. 96 97 98
  

• C. 98 97 96
  

• D. NameError

>>colors = ["red", "green", "burnt sienna", "blue"]

>> "yellow" in colors

What is the result of the yellow in colors expression?

• ValueError: 'yellow' is not in list

• 4

• 3

• False

What’s the main difference between Python lists and tuples?

• Lists can hold any data type and tuples can only contain int and str objects.

• Lists are immutable and tuples are mutable.

• Lists are faster and tuples are slower.

• Lists are mutable and tuples are immutable.

Write the Python code that prints out Captain Kirk’s email address from the employee dictionary below:

employee = { "id": 1701, "name": "James T Kirk", "email": "[e-mail]", "position": "captain", }

# Add your code below:

• What will be the output of the following Python code? >>>t = (1, 2) >>>2 * t

• • A.

    (1, 2, 1, 2)

• • B.

    [1, 2, 1, 2]

• • C.

    (1, 1, 2, 2)

• • D.

    [1, 1, 2, 2]

Suppose t = (1, 2, 4, 3), which of the following is incorrect?

• a) print(t[3])
  

• b) t[3] = 45
  

• c) print(max(t))
  

• d) print(len(t)
