OPERATORS AND EXPRESSIONS  

 

Q1. Write a Python script to input roll number and marks in three subjects of a student. Calculate and display the total and percentage.

roll=input("roll number")

e=eval(input("Enter marks of eng"))

a=eval(input("Enter marks of math"))

s=eval(input("Enter marks of science"))

num=(e+a+s)

Per=((num*100)/300)

print(“total marks”, num)

print("percentage", Per)

Q2. Write a Python script to input a temperature in Celsius and convert it into Fahrenheit.

print("Temperature Converter")

a=eval(input("Temperature in Celsius"))

b=(9/5)*a

f=b+32

print("Temperature in Fahrenheit", f)

Q3. Write a Python script to input the values of a,b,c and calculate the roots of the quadratic equation.

print("Solving Quadratic Equation")

a=eval(input("Enter coefficient of x^2: "))

b=eval(input("Enter coefficient of x: "))

c=eval(input("Enter constant value: "))

d=b**2

f=4*a*c

h=d-f

x1=(-b+h**0.5)/(2*a)

x2=(-b-h**0.5)/(2*a)

print("First root: ", x1)

print("Second root: ", x2)

Q4. Write a Python script to input sides of a triangle and calculate its area.

p=eval(input("Length of a"))

b=eval(input("Length of b"))

c=eval(input("Length of c"))

s=(p+b+c)/2

Area=((s*(s-p)*(s-b)*(s-c))**0.5)

print("the Area is: ", Area)

Q5. Write a Python script to input the values of Principal, Rate, and Time and calculate Simple Interest and Compound Interest.

p=eval(input("Enter Principal:"))

r=eval(input("Enter Rate of Interest:"))

t=eval(input("Enter the time period:"))

s=(p*r*t)/100

print("Simple Interest: ", s)

c=(p*(1+r/100)**t)

print("Compound Interest: ", c)

Q6. Write a Python script to input employee number, basic, HRA, DA and IT of an employee. Calculate and display the net salary. (net salary=basic+HRA+DA-IT)

n=(input("Enter Employee Name"))

a=eval(input("Enter Employee Number"))

b=eval(input("Enter Basic"))

m=eval(input("Enter HRA"))

k=eval(input("Enter DA"))

l=eval(input("Enter IT"))

tot=(b+m+k)-l

print("NET SALARY", tot)

Q7. Write a Python script to input Item number, Price/unit, quantity and discount. Calculate and display the net amount to be paid.

input("Item name: ")

input("Item number: ")

a=eval(input("Price per item: "))

b=eval(input("Quanity: "))

d=eval(input("Discount: "))

f=a*b

m=d*a

e=m//100

p=f-e

print("FINAL AMOUNT:", p)

Q8. Write a Python script to input time in seconds and display the number of hours, minutes and seconds in the given seconds.

s=int(input("Enter time in seconds: "))

h=s//3600

m=s%3600

m1=m//60

s2=m%60

print("Time: ", "Hours:", h, "Minutes:", m1, "Seconds:", s2)

Q9. Write a Python script to input length in meters and convert it into centimeters.

a=eval(input(“enter length in metres”))

b=a*100

print(“length in centimetres is”, b))

Q10. Write a Python script to input a three digits number and find the sum of its digits.

num=eval(input("Enter a 3 digit number: "))

a=num%10

num=num//10

b=num%10

num=num//10

print("The sum of the digits is: ", a+b+num)
