(a) Serial_no.(b) 1st_Room(c) Hundred$(d)
Total Marks(e) Total_Marks(f) total-Marks(g)
_Percentage(h) TrueQ2. Write the corresponding Python assignment statements:
(a) Assign 10 to variable length and 20 to variable
breadth.(b) Assign the average of values of variables length and
breadth to a variable sum.(c) Assign a list containing strings
‘Paper’, ‘Gel Pen’, and ‘Eraser’ to a variable stationery.(d)
Assign the strings ‘Mohandas’, ‘Karamchand’, and ‘Gandhi’ to variables
first, middle and last.(e) Assign the concatenated value of
string variables first, middle and last to variable fullname.Make
sure to incorporate blank spaces appropriately between different parts
of names.Q3. Write logical expressions corresponding to the following
statements in Python and evaluate the expressions (assuming variables
num1, num2, num3, first, middle, last are already having meaningful
values):(a) The sum of 20 and –10 is less than 12.(b) num3
is not more than 24.(c) 6.75 is between the values of integer’s
num1 and num2.(d) The string ‘middle’ is larger than the string
‘first’ and smaller than the string ‘last’.(e) List Stationery
is empty.Q4. Add a pair of parentheses to each expression so that it evaluates
to True.(a) 0 == 1 == 2(b) 2 + 3 == 4 + 5 == 7(c) 1
< -1 == 3 > 4Q5. Write the output of the following:(a)num1 = 4num2
= num1 + 1num1 = 2print (num1, num2)(b)num1,
num2 = 2, 6num1, num2 = num2, num1 + 2print (num1,
num2)(c)num1, num2 = 2, 3num3, num2 = num1, num3 +
1print (num1, num2, num3)Q6. Which data type will be used to represent the following data
values and why?(a) Number of months in a year(b) Resident
of Delhi or not(c) Mobile number(d) Pocket money(e)
Volume of a sphere(f) Perimeter of a square(g) Name of the
student(h) Address of the studentQ7. Give the output of the following when num1 = 4, num2 = 3, num3 =
2(a) num1 += num2 + num3(b) print (num1)(c)
num1 = num1 ** (num2 + num3)(d) print (num1)(e) num1 **=
num2 + c(f) num1 = '5' + '5'(g) print(num1)(h)
print(4.00/(2.0+2.0))(i) num1 = 2+9*((3*12)-8)/10(j)
print(num1)(k) num1 = float(10)(l) print (num1)(m)
num1 = int('3.14')(n) print (num1)(o) print(10 != 9 and 20
>= 20)(p) print(5 % 10 + 10 < 50 and 29 <= 29)Q8. Categorise the following as syntax error, logical error or
runtime error: (a) 25 / 0(b) num1 = 25; num2 = 0;
num1/num2Q9. A dartboard of radius 10
units and the wall it is hanging
on are represented using a two-dimensional coordinate
system, with the board’s centre at coordinate (0,0). Variables x and y
storeThe x-coordinate and the y-coordinate of a dart that hits
the dartboard. Write a Python expression using variables x and y that
evaluates to True if the dart hits (is within) the dartboard, and then
evaluate the expression for these dart coordinates:(a) (0, 0)(b)
(10, 10)(c) (6, 6)(d) (7, 8)Q10. Write a Python program to convert temperature in degree Celsius
to degree Fahrenheit. If water boils at 100 degree C and freezes as 0
degree C, use the program to find out what is the boiling point and
freezing point of water on the Fahrenheit scale. (Hint: T (°F) = T
(°C) × 9/5 + 32)Q11. Write a Python program to calculate the amount payable if money
has been lent on simple interest. Principal or money lent = P, Rate =
R% per annum and Time = T years. Then Simple Interest (SI) = (P x R x
T)/ 100.Amount payable = Principal + SI.P, R and T are
given as input to the program.Q12. Write a program to calculate in how many days a work will be
completed by three persons A, B and C together. A, B, C take x days, y
days and z days respectively to do the job alone. The formula to
calculate the number of days if they work together is xyz/(xy + yz +
xz) days where x, y, and z are given as input to the program.Q13. Write a program to enter two integers and perform all arithmetic
operations on them.Q14. Write a program to swap two numbers using a third
variable.Q15. Write a program to swap two numbers without using a third
variable.Q16. Write a program to repeat the string ‘‘GOOD MORNING” n times.
Here n is an integer entered by the user.Q17. Write a program to find average of three numbers.Q18. The volume of a sphere with radius r is 4/3Ï€r3. Write a Python
program to find the volume of spheres with radius 7cm, 12cm, 16cm,
respectively.Q19. Write a program that asks the user to enter one's name and age.
Print out a message addressed to the user that tells the user the year
in which he/she will turn 100 years old.Q20. The formula E = mc**2 states that the equivalent energy (E) can
be calculated as the mass (m) multiplied by the speed of light (c =
about 3×108 m/s) squared. Write a program that accepts the mass of an
object and determines its energy.Q21. Presume that a ladder is put upright against a wall. Let
variables length and angle store the length of the ladder and the
angle that it forms with the ground as it leans against the
wall. Write a Python program to compute the height reached by
the ladder on the wall for the following values of length and
angle:(a) 16 feet and 75 degrees(b) 20 feet and 0
degrees(c) 24 feet and 45 degrees(d) 24 feet and 80
degrees**
