TCS Python Hackathon - Python Hands-on

 

Q1. Write a python code to take a string as input and count the number of vowels in the string. Your code is expected to print the count value as output. Count should include vowels in lower and upper cases.

def countVowels(inp):

    count = 0

    vowels = ['a','e','i','o','u','A','E','I','O','U']

    for character in inp:

        if character in vowels:

            count = count + 1

    return count

if __name__=='__main__':

    inp = input()

    output = countVowels(inp)

    print(output)

Q2. Write a python code to count how many prime integers are there in a given list of integers.

def countPrimeNumbers(numbers):

    count = 0

    for elements in numbers:

        if(elements == 0 or elements == 1):

            continue

        else:

            for i in range(2,elements//2+1):

                if(elements % i == 0):

                    break

            else:

                count = count +1

    return count

if __name__ == '__main__':

    numbers=[]

    count=int(input())

    for i in range(count):

        numbers.append(int(input()))

    print(countPrimeNumbers(numbers))

Q3.  Write a python code to which will calculate the percentage and grade of a student based on the percentage of marks.

Define a class  Student  with attributes roll(number), student name(name) and a list which stores the marks scored by the student(mark_list).

Provide following methods to the class:

 1. calculate_percentage()

 2. find_grade() 

class Student:

    def __init__(self,roll,name,marks_list):

        self.roll = roll

        self.name = name

        self.marks_list = marks_list

        self.percent = None

    def calculate_percentage(self):

        summ = sum(self.marks_list)

        count = len(self.marks_list)

       

        percentage = summ//count

        self.percent = percentage

       

        return percentage

    def find_grade(self):

        percent = self.percent

        if(percent >=  80):

            grade = 'A'

        elif(percent >= 60):

            grade = 'B'

        elif(percent >= 40):

            grade = 'C'

        else:

            grade = 'F'

        return grade

       

if __name__ == '__main__':

    roll=int(input())

    name=input()

    count=int(input())

    marks=[]

    for i in range(count):

        marks.append(int(input()))

    s=Student(roll,name,marks)

    print(s.calculate_percentage())

    print(s.find_grade())

Q4.  Write a python code as per below prototype  to fulfill the below requirements.

    a.  Which will add couples of employee to the organization based on the count.

    b.  Display the employee age,whose id is given on the input.

    c. Display the count of employees whose age is greater than the given age as input.

Define a class Employee with the attributes  name, id , age, gender.

Define a class Organisation  with attributes to have a name for the organisation, and a list to store list of employees.

Provide following methods to the class:

 1. addEmployee()

 2. getEmployee()

 3. findEmployeeAge()

 4. countEmployee() 

 

class Employee:

    def __init__(self,name,Id,age,gender):

        self.name = name

        self.Id   = Id

        self.age  = age

        self.gender = gender

class Organisation:

    def __init__(self,organizationName,employee_list):

        self.organizationName = organizationName

        self.employee_list = employee_list

   

    def addEmployee(self,name,Id,age,gender):

        empObj = Employee(name,Id,age,gender)

        self.employee_list.append(empObj)

    def getEmployeeCount(self):

        count = len(self.employee_list)

        return count

   

    def findEmployeeAge(self,Id):

        for i in self.employee_list:

            if(i.Id == Id):

                return i.age

        return -1

   

    def countEmployees(self,Age):

        countEmp = 0

        for i in self.employee_list:

            if(i.age > Age):

                countEmp = countEmp + 1

        return countEmp

if __name__ == '__main__':

    employees=[]

    o = Organisation('XYZ',employees)

    n=int(input())

    for i in range(n):

        name=input()

        id=int(input())

        age=int(input())

        gender=input()

        o.addEmployee(name,id,age,gender)

    id=int(input())

    age=int(input())

    print(o.getEmployeeCount())

    print(o.findEmployeeAge(id))

    print(o.countEmployees(age))
