Here, i will provide the solution of this above all programs.

  1. Program to print general information like Hello and student name.

print(“Message – Hello”)

print(“Student Name – Tanmay Patel”)

2. Program to calculate Sum, Subtract, Multiply, divide of two different values.

#Addition

num1 = int(input(“Enter first number: “))
num2 = int(input(“Enter second number: “))
sum = num1 + num2
print(“Sum:”, sum)

#Subtraction

num1 = int(input(“Enter first number: “))
num2 = int(input(“Enter second number: “))
difference = num1 – num2
print(“Difference:”, difference)

#Multiplication

num1 = int(input(“Enter first number: “))
num2 = int(input(“Enter second number: “))
product = num1 * num2
print(“Product:”, product)

#Division

num1 = int(input(“Enter first number: “))
num2 = int(input(“Enter second number: “))
quotient = num1 / num2
print(“Quotient:”, quotient)

3. Program to print a simple table of number 7.

#Printing a table of the number 7

no = 7

print(“Multiplication Table of”, no)
print(“—————————“)

for i in range(1, 11):
print(no, “x”, i, “=”, no * i)

4. Program to convert value from meter to centimeter

#Convert value from meters to centimeters

meters = float(input(“Enter value in meters: “))
centimeters = meters * 100
print(“Value in centimeters:”, centimeters)

5. To calculate percentage of different 5 subjects

Oracle=int(input(“Enter marks of Oracle:”))

C=int(input(“Enter marks of C:”))

CPP=int(input(“Enter marks of CPP:”))

HTML=int(input(“Enter marks of HTML:”))

PHP=int(input(“Enter marks of PHP:”))

total=Oracle+C+CPP+HTML+PHP

per=total/5

print(“percentage of 5 subjects marks:”, per)

6. Program to calculate area of circle

import math

radius = float(input(“Enter the radius of the circle: “))

area = math.pi * radius ** 2

print(“The area of the circle with radius”, radius, “is:”, area)

7. Program to interchange two different values

a = int(input(“Enter value of a: “))
b = int(input(“Enter value of b:”))

temp = a
a = b
b = temp

print(“a =”, a)
print(“b =”, b)

8. Program to calculate area of triangle with base and height

Base=float(input(“Enter base:”))

Height=float(input(“Enter height:”))

area=Base*Height/2

print(“Area of triangle:”, area)

9. Create a list in python of ranker students with the following names- Tanmay, Khushi, Vrinda, Ananya, Tushar. Perform the following tasks on the list in sequence

  1. Print the whole list
  2. Add the name Rudra at the end
  3. Delete the name Khushi from the list
  4. Remove the name which is at the fourth position

stu_lst=[‘Tanmay’,’Khushi’,’Vrinda’,’Ananya’,’Tushar’]

#Print the whole list

print(stu_lst)

#Add the name Rudra at the end

stu_lst.append(‘Rudra’)

#Delete the name Khushi

#method – 1

del stu_lst[‘Khushi’]

#Method – 2

stu_lst.pop(stu_lst.index(‘Khushi’))

#remove the item at Fourth position

stu_lst.remove(stu_lst[4]) print(stu_lst)

10. Create a list no[13, 15, 8, 90,55, 28]

  1. Print the length of list
  2. Print the elements from 1st to 3rd position (With positive indexing)

no=[13,15,8,90,55,28]

#printing the length of the list

print(“Length of list is:”, len(num))

#Print the elements from first to third position (With positive indexing)

print(“1st to 3rd Position elements:”,num[1:3])

11. Create a list of the first 10 even numbers, add 1 into each list item, and print the final list.

l=list(range(2,21,2))

print(l)

for i in range(len(l)):

l[i]=l[i]+1

print(l)

12. Create a list list_1 [11, 21, 13, 14]. Add the elements [15, 17, 25] using the extend function. Now sort the final list in ascending order and print it.

list_1=[11,21,13,14]

list_1.extend([15,17,25])

list_1.sort()

print(list_1)

13. Program to check the grade of student

per=float(input(“Enter Percentage:”))

if per>=91 and per<=100:

print(“Grade: A”)

elif per>=71 and per<=90:

print(“Grade: B”)

elif per>=51 and per<=70:

print(“Grade: C”)

elif per>=35 and per<=50:

print(“Grade: D”)

else:

print(“Imrovemenet required…”)

14. Program to check if the number is positive, negative or zero

n=int(input(“Enter any number to check:”))

if n>0:

print(“No is positive”)

elif n<0:

print(“No is negative”)

else:

print(“Zero”)

15. Program to print first 10 even numbers

for i in range(1,21,2):

print(i)

16. Program to print odd numbers from 1 to n.

for i in range(1,21,2):

print(i)

17. Program to print sum of first 10 natural numbers.

s=0

for i in range(1,11):

s+=i

print(s)

18. Program to find the sum of all numbers sorted in a list.

l=[10,20,30,40,50]

s=0

for i in l:

s+=i

print(s)
