Question 1: Given a two integer numbers return their product and  if the product is greater than 1000, then return their sum

Reference article for help:

• Accept user input in Python
• Calculate an Average in Python

Given:

number1 = 20
number2 = 30

Expected Output:

The result is 600

Given:

number1 = 40
number2 = 30

Expected Output:

The result is 70

def multiplication_or_sum(num1, num2):
    product = num1 * num2
    if product <= 1000:
        return product
    else:
        return num1 + num2

number1 = 20
number2 = 30

print("\n")
result = multiplication_or_sum(number1, number2)
print("The result is", result)

Question 2: Given a range of first 10 numbers, Iterate from start number to the end number and print the sum of the current number and previous number

Reference article for help:

• Python range() function
• Calculate sum and average in Python

Expected Output:

Printing current and previous number sum in a given range(10)

Question 3: Given a string, display only those characters which are present at an even index number.

For example str = "pynative" so you should display ‘p’, ‘n’, ‘t’, ‘v’.

Reference article for help: Python Input and Output

Expected Output:

Orginal String is  pynative
Printing only even index chars
p
n
t
v

def printEveIndexChar(str):
  for i in range(0, len(str)-1, 2):
    print("index[",i,"]", str[i] )

inputStr = "pynative" 
print("Orginal String is ", inputStr)

print("Printing only even index chars")
printEveIndexChar(inputStr)

Question 4: Given a string and an integer number n, remove characters from a string starting from zero up to n and return a new string

For example, removeChars("pynative", 4) so output must be tive. Note: n must be less than the length of the string.

def removeChars(str, n):
  return str[n:]

print("Removing n number of chars")
print(removeChars("pynative", 4))

    reverseNum = 0
    while (number > 0):
        reminder = number % 10
        reverseNum = (reverseNum * 10) + reminder
        number = number // 10
    if (originalNum == reverseNum):
        return True
    else:
        return False

def mergeList(listOne, listTwo):
    print("First List ", listOne)
    print("Second List ", listTwo)
    thirdList = []
    
    for num in listOne:
        if (num % 2 != 0):
            thirdList.append(num)
    for num in listTwo:
        if (num % 2 == 0):

Question 11: Write a code to extract each digit from an integer, in the reverse order

Expected Output:

For example, if the given int is 7536, the output shall be “6 3 5 7“, with a space separating the digits.

number = 7536
print("Given number", number)
while (number > 0):
    # get the last digit
    digit = number % 10
    
    # remove the last digit and repeat the loop
    number = number // 10
    print(digit, end=" ")

Question 12: Calculate income tax for the given income by adhering to the below rules

Expected Output:

For example, suppose that the taxable income is $45000 the income tax payable is

$10000*0% + $10000*10%  + $25000*20% = $6000.

taxPayable = 0
print("Given income", income)

if income <= 10000:
    taxPayable = 0
elif income <= 20000:
    taxPayable = (income - 10000) * 10 / 100

Question 15: Write a function called exponent(base, exp) that returns an int value of base raises to the power of exp.

Note here exp is a non-negative integer, and the base is an integer.

Expected Output:

Case 1:

base = 2
exponent = 5

2 raises to the power of 5 is: 32 i.e. (2 *2 * 2 *2 *2 = 32)

Case 2:

base = 5
exponent = 4

5 raises to the power of 4 is: 625 i.e. (5 *5 * 5 *5 = 625)

def exponent(base, exp):
    num = exp
    result = 1
    while num > 0:
        result = result * base
        num = num - 1
    print(base, "raises to the power of", exp, "is: ", result)

exponent(5, 4)
