In this students get weekly assignments that they have to complete every week. Here we will show you or give you all the answers for the python quiz, These answers are for all those who have confusion in the questions or they don’t want to submit wrong answers.

Q:1. How do you declare a dictionary in python ?

·         dict [“key”:”value”]

·         dict = {“key”:”value”}

·         Dict = {“key” - “value”}

·         Dict = [“key”:”value”]

Answer: dict = {“key”:”value”}

Reason: Dictionary id listed in curly brackets inside these curly brackets, key and value are declared, each key is separated from its value by a colon (:), while commas separate each element.

Q:2. What will be the output of the following code:

        dict = { x:x for x in range(1,2) }

        print(dict)

·         {}

·         {x:x,x:x,x:x}

·         {1: 1, 2: 2}

·         {1: 1}

Answer: {1: 1}

Reason: As the for loop runs upto one hence {1:1} will print.

Q:3. In python 3.x, Which of the following statement is true for following code:

        age = input (“Please enter your age”)

·         Age will be integer type.

·         It removes trailing spaces.

·         age variable's type will be Whatever type is given to it

·         None of the above

Answer: None of the above

Reason: We are asking for the age in the age = input("Please enter your age"), hence none of the above statement is true hence answer is none of the above.

Q:4. What will be the output of the following program ?

        int =5

        while int <=-1:

            print (int)

            int = int -1

·         3

              2

·         blank(nothing will be printed)

·         5

              4

              3

·         5

              4

              3

              2

              1

Answer: blank(nothing will be printed)

Reason: As in the program while condition is not true hence it will not run, and out side the while loop nothing is printed therefore second option is correct.

Q:5. What will be the output of the following program ?

        int =3

        while int >=2:

            print (int)

            int = 1

·         3

·         2

·         3 2

·         Error in code

Answer: 3

Reason: while condition is satisfied hence it will print 3 as it declared above. But in end int = 1 it will not print as print statement is not written.
