TCS aspire Python Assignments

1. Write a Python program to find whether a given number (accept from the user) is prime or not,print out an appropriate message to the user.?

n=int(input('Enter Number'))

if n<0:

    print("Given Number is Negative")

elif n==2:

    print(n,"is prime")

else:

    for i in range(2,n):

        if (n%i)==0:

            print(n,"is not prime")

            break

    else:

        print(n,"is prime number")

2. Write a Python program which accept the radius of a circle from the user and compute the area.

from math import pi

r = float(input ("Enter the Radius of circle: "))

print ("The area of the circle is" + str(r) + " is: " + str(pi * r**2))

3. Write a Python program to print all even numbers from a given list of numbers. The list is terminated by -99999.

list= [1, 2, 3, 4, 5, 6, 7, 8, 9, -99999]

print("Even Numbers are")

for x in list: 

        if not x % 2: 

             print(x,end=' ') 

4. Write a Python program to find the occurrence of a given number in a given list of numbers.

list = [1,2,3,1,4,1,2,5,1,2,3,1]

print("Number Of occurrence of given number is",list.count(1))

5. Write a Python program that accept a word from the user and reverse it.

word = input("Give A Word to Reverse: ")

 for char in range(len(word) - 1, -1, -1):

  print(word[char], end="")

6. Write a Python program that accept a number and prints the reverse of it.

n = int(input("Please Give A Number: "))

R = 0

while(n > 0):

    Reminder = n %10

    R = (R *10) + Reminder

    n = n //10

print("Reverse of Given Number is = %d" %R)

7. Write a Python program that accept a number and finds the summation of the digits in the number.

Number = int(input("Please Give A Number: "))

Sum = 0

while(Number > 0):

    Reminder = Number % 10

    Sum = Sum + Reminder

    Number = Number //10

print("Sum of the digits of Given Number = %d" %Sum)

8. Write a Python program to copy the content of a given file to another. Take the file names as input from user.

filename=input("Enter Filename ,")

to_readfile=open("ex.py", "r")

try:

      reading_file=to_readfile.read()

      writefile=open(filename, "w")

      print("Succefully Copied afile")

      try:

           writefile.write(reading_file)

      finally:

           writefile.close()

finally:

      to_readfile.close()

9. Define a class student with attributes roll number, name and score and methods to find grade. Grade is ‘A’ if score >=80, grade is ‘B’ if score >=60 and score<80, grade is ‘C’ if score >=50 and score<60 otherwise ‘F’.

class Student_Grade:

    def __init__(self, RollNo,Name,Score):

        self.RollNo = RollNo

        self.Name = Name

        self.Score = Score

    def grade(self):

        print("Roll No Of the Student is:",self.RollNo)

        print("Name Of the Student is:",self.Name)

        if(self.Score>=80 and self.Score<=100):

            print("Your Grade is A")

        elif(self.Score>=50 and self.Score<=60):

            print("Your Grade is B")

        else:

            print("Your Grade is F")

        return None

while True:

            print("Enter Roll Number, Name, Score of the Student: ")

            rollnumber = input()

            name = input()

            score = int(input())

            r=Student_Grade(rollnumber,name,score)

            r.grade()

            break

10. Define a class named Circle constructed by a radius and two methods which will compute the area and the perimeter of a circle and one more method which will check whether the area is greater than a given value or not.

from math import pi

class Circle:

    def __init__(self,r):

        self.r = r

    def area(self):

        return pi * self.r * self.r

    def perimeter(self):

        return 2 * pi * self.r

    def check(self,area):

        if area > self.r:

            print("Area is Greater than Given Ridus")

r=Circle(5)

a=r.area()

print("Circle area is:",a)

print("Perimetere is:",r.perimeter())

r.check(a)

11. Define a class Shape with its sub class Square . The Square has an initialize function which takes as argument a length. Both classes have a function findArea which can print the area of the shape where Shape's area is 0 by default.

class Shape:

    def area(side):

        print("Area form Shape class:",side * side)

class Square(Shape):

        def __init__(self,side):

            self.side = side

        def area(self,area=0):

            print("Area from Square class:",self.side * self.side)

            Shape.area(self.side)

Square(5).area()

12. Define a class Item and its two child classes: Perishable and NonPerishable. All classes have attribute price a method "calculateSalePrice" which can print "price + (price * .1) " for nonperishable class and "price + 500" for perishable class.

class Pershable:

    def calculateSalePrice(price):

        print("Pershable Price :",price+500)

class NonPershable(Pershable):

      def __init__(self,price):

        self.price = price

      def calculateSalePrice(self):

          print("Nonpershable Price :",self.price + (self.price * .1))

          Pershable.calculateSalePrice(self.price)

x=NonPershable(100)

x.calculateSalePrice()

#!/usr/bin/python

# python program for items and its two child classes perishable and non perishable

class Items(object):

        def __init__(self,price):

               self.price = price

       

        def CalculateSalePrice(self):

               pass

class Perishable(Items):

        def __init__(self,price):

               self.price = price

       

        def CalculateSalePrice(price):

               print('The price is:',(price+500))

class NonPerishable(Items):

        def __init__(self,price):

               self.price = price

       

        def CalculateSalePrice(price):

               print('The price is:',(price+(price * 0.1)))

i = Items(10)

i.CalculateSalePrice()

i.CalculateSalePrice()
