10
9
Assign value 5 to a variable using assignment
operator(=) Multiply it with 2 to generate 10 and subtract 1 to generate 9.
Ans:
a=5
b=a*2
c=b-1
print(a)
print(b)
print(c)
# 5) Modify above (no. 4 program) program so as to print
output as 5@10@9.
Ans:
a=5
b=a*2
c=b-1
print(a,"@",b,"@",c)
# 6) Write a python program that accepts radius of a
circle and prints its area.

subj2 marks : "))
c=float(input("Enter
subj3 marks : "))

subj5 marks : "))
avg = (a+b+c+d+e)/5
print("Average
of 5 subject marks : ", avg)
# 8) Write a short program that asks for your height
in centimetres and then converts your height to feet and inches.
(
1 foot = 12 inches, 1 inch = 2.54 cm ).
Output:
Enter your height in cm: 100
Height is 3.0 ft and 3.37 inch
Ans:
height_cm = float(input("Enter
your height in cm: "))
# Convert height to inches
height_in = height_cm /
2.54
# Get feet by taking floor
division with 12
feet = height_in // 12
# Get inches by taking
modulo division with 12
inches = height_in % 12
# Round off the inches to
2 decimal places
inches_rounded =
format(inches, ".2f")
# Print out the height in
feet and inches
print(f"Height
is {feet} ft and {inches_rounded} inch")
# 9) The real
floor division operator is “//”. It returns floor value for both integer and
floating point arguments.
Output:
2
-3
2.0
-3.0
Ans:
#
"//" for both integers and floating points
print(5//2)
print(-5//2)
print(5.0//2)
print(-5.0//2)
# 10) Formatted
string literals (f-strings)
Note: * A
new string formatting mechanism known as Literal String
Interpolation or more commonly as F-strings (because
of the leading f character preceding the string literal).
* To create an f-string, prefix the
string with the letter “ f ”.
Output:
Enter your name : Chanchal Sarkar
Enter your age : 120
Hello, My name is Chanchal Sarkar and I'm 120 years
old.
Ans:
# introducing f-string
nm=input("Enter your
name : ")
age=int(input("Enter
your age : "))
print(f"Hello,
My name is {nm} and I'm {age} years old.")
# 11) Basic
formatting with format().
The format() method allows the use of simple
placeholders for formatting.
Output:
Hello CS, your balance is 230.23
Hello CS, your balance is 2000.5
Hello CS, your balance is 12500.0
Hello CS, your balance is 60500.25
Ans:
# Basic formatting for
default, positional and keyword arguments
# default arguments
print("Hello {}, your
balance is {}".format("CS", 230.23))
# positional arguments
print("Hello {0},
your balance is {1}".format("CS", 2000.50))
# keyword arguments
print("Hello {name},
your balance is {blc}".format(name="CS", blc=12500.00))
# mixed arguments
print("Hello
{0}, your balance is {blc}".format("CS", blc=60500.25))
# 12) WAP to read a number n and print n2,
n3 and n4.
Output:
Enter a no. : 5.0
Value of n^2:
25.0
Value of n^3:
125.0
Value of n^4:
625.0
Ans:
import math
n=float(input("Enter
a no. : "))
a=math.pow(n,2)
b=math.pow(n,3)
c=math.pow(n,4)
print("Value of n^2:
",a)
print("Value of n^3:
",b)
print("Value
of n^4: ",c)
# 13) WAP to find area of a rectangle.
Output:
Enter length of Rectangle : 4
Enter Breadth of Rectangle : 8
Area is : 32.0
Ans:
L=float(input("Enter

60000.0
Compound amount :
176234.16832000008
Compound interest :
76234.16832000008
Ans:
p =
float(input("Enter the principal amount: "))
r =
float(input("Enter the interest rate: "))
t =
float(input("Enter the time in years: "))
# Simple Interest
Calculation
SI=(p*r*t)/100
# Compound Interest
Calculation
CI = p * (pow((1 + r /
100), t))
I = CI - p
print("Simple
interest : ", SI)

print("Student name :
",name,"-Student class : ",cl,"-Student age : ",age)
print()
print()
print("Student
name : ",name,"\nStudent class : ",cl,"\nStudent age :
",age)
# 17) WAP to input a single digit(n) and print a 3
digit number created as <n(n + 1)(n + 2)> e.g., if you input 7, then it

Output:
Enter a single digit number: 5
The three digit number is : 567
Ans:
n = int(input("Enter
a single digit number: "))
if n>0 and n<8:
a = n + 1
b = n + 2
