Exercise 1: Given two integer numbers return their product. 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

number1 = 20
number2 = 30

The result is 600

number1 = 40
number2 = 30

The result is 70

def multiplication_or_sum(num1, num2):
    # calculate product of two number
    product = num1 * num2
    # check if product is less then 1000
    if product <= 1000:
        return product
    else:
        # product is greater than 1000 calculate sum
        return num1 + num2

# first condition
result = multiplication_or_sum(20, 30)
print("The result is", result)

# Second condition
result = multiplication_or_sum(40, 30)
print("The result is", result)

Exercise 2: Given a range of the first 10 numbers, Iterate from the start number to the end number, and In each iteration 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 range(10)
Current Number 0 Previous Number  0  Sum:  0
Current Number 1 Previous Number  0  Sum:  1
Current Number 2 Previous Number  1  Sum:  3
Current Number 3 Previous Number  2  Sum:  5
Current Number 4 Previous Number  3  Sum:  7
Current Number 5 Previous Number  4  Sum:  9
Current Number 6 Previous Number  5  Sum:  11
Current Number 7 Previous Number  6  Sum:  13
Current Number 8 Previous Number  7  Sum:  15
Current Number 9 Previous Number  8  Sum:  17

def sumNum(num):
    previousNum = 0
    for i in range(num):
        sum = previousNum + i
        print("Current Number", i, "Previous Number ", previousNum," Sum: ", sum)
        previousNum = i

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

Exercise 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)

Exercise 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))

    firstElement = numberList[0]
    lastElement = numberList[-1]
    if (firstElement == lastElement):
        return True
    else:
        return False

numList = [10, 20, 30, 40, 10]
print("result is", isFirst_And_Last_Same(numList))

Exercise 6: Given a list of numbers, Iterate it and print only those numbers which are divisible of 5

Expected Output:

Given list is  [10, 20, 33, 46, 55]
Divisible of 5 in a list
10
20
55

def findDivisible(numberList):
    print("Given list is ", numberList)
    print("Divisible of 5 in a list")
    for num in numberList:
        if (num % 5 == 0):
            print(num)

numList = [10, 20, 33, 46, 55]

Given:

str = "Emma is good developer. Emma is a writer"

Expected Output:

Emma appeared 2 times

sampleStr = "Emma is good developer. Emma is a writer"
# use count method of a str class

def count_emma(statement):
    print("Given String: ", statement)
    count = 0
    for i in range(len(statement) - 1):
        count += statement[i: i + 4] == 'Emma'
    return count

count = count_emma("Emma is good developer. Emma is a writer")
print("Emma appeared ", count, "times")

Exercise 8: Print the following pattern

1 
2 2 
3 3 3 
4 4 4 4 
5 5 5 5 5

Reference article for help: Print Pattern using for loop

for num in range(10):
    for i in range(num):
        print (num, end=" ") #print number
    # new line after each row to display pattern correctly
    print("\n")

Exercise 9: Reverse a given number and return true if it is the same as the original number

Expected Output:

original number 121
The original and reverse number is the same

original number 125

def reverseCheck(number):
    print("original number", number)
    originalNum = number
    reverseNum = 0
    while (number > 0):
        reminder = number % 10
        reverseNum = (reverseNum * 10) + reminder
        number = number // 10
    if (originalNum == reverseNum):
        return True
    else:
        return False

print("The original and reverse number is the same:", reverseCheck(121))

Exercise 10: Given a two list of numbers create a new list such that new list should contain only odd numbers from the first list and even numbers from the second list

list1 =  [10, 20, 23, 11, 17]
list 2 = [13, 43, 24, 36, 12]

result List is [23, 11, 17, 24, 36, 12]

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):
            thirdList.append(num)

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

Expected Output:

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

number = 7536

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

Expected output

i.e. (5 *5 * 5 *5 = 625)

def exponent(base, exp):
    num = exp
    result = 1
    while num > 0:
        result = result * base
        num = num - 1
