• Question 1 | Level 1

Question:

Write a program which will find all such numbers which are divisible by 7 but are not a multiple of 5, between 2000 and 3200 (both included). The numbers obtained should be printed in a comma-separated sequence on a single line.

Solution:

print("Number(s) divisible by 7 but not 5 in the range 2000, 3200 -\n")
number = []
for i in range(2000, 3201):
    if (i % 7 == 0) and (i % 5 != 0):
        number.append(str(i))
print(",".join(number))

• Question 2 | Level 1

Question:

Write a program which can compute the factorial of a given numbers. The results should be printed in a comma-separated sequence on a single line. Suppose the following input is supplied to the program: 8 Then, the output should be: 40320

Solution:

def fact(x):
    if x == 0:
        return 1
    return x * fact(x - 1)


print("Program to computer factorial of a number")
print("\nEnter a number: ")
number = int(input())
print("\nFactorial of {0} is = {1}".format(number, fact(number)))

• Question 3 | Level 1

Question:

With a given integral number n, write a program to generate a dictionary that contains (i, i*i) such that is an integral number between 1 and n (both included). and then the program should print the dictionary. Suppose the following input is supplied to the program: 8 Then, the output should be: {1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64}

Solution:

def create_dict(integer):
    dictionary = {}
    temp = 1
    while temp <= integer:
        dictionary[temp] = temp * temp
        temp += 1
    return dictionary


print("Enter an Integer")
integer = int(input())
if integer > 0:
    print(create_dict(integer))
else:
    print("Integer should be greater than 1!")

• Question 4 | Level 1

Question:

Write a program which accepts a sequence of comma-separated numbers from console and generate a list and a tuple which contains every number. Suppose the following input is supplied to the program: 34,67,55,33,12,98 Then, the output should be: ['34', '67', '55', '33', '12', '98'] ('34', '67', '55', '33', '12', '98')

Solution:

values = input("Enter Numbers: ")
li = values.split(",")
tu = tuple(li)
print(li)
print(tu)

• Question 5 | Level 1

Question: Define a class which has at least two methods: getString: to get a string from console input printString: to print the string in upper case. Also please include simple test function to test the class methods.

Solution:

class IOString(object):
    def __init__(self):
        self.string = ""

    def GetString(self):
        self.string = str(input("Enter String: "))

    def PrintString(self):
        print(self.string.upper())


st = IOString()
st.GetString()
st.PrintString()

• Question 6 | Level 2

Question: Write a program that calculates and prints the value according to the given formula: Q = Square root of [(2 * C * D)/H] Following are the fixed values of C and H: C is 50. H is 30. D is the variable whose values should be input to your program in a comma-separated sequence. Example Let us assume the following comma separated input sequence is given to the program: 100,150,180 The output of the program should be: 18,22,24

Solution:

import math
def Calculate(data):
    list = []
    C = 50
    H = 30
    for number in data:
        list.append(str(round(math.sqrt((2*C*int(number)/H)))))
    print(",".join(list))

string = input("Input Number(s): ")
Calculate(string.split(","))
