Question 1: Accept two int values from the user and 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

Expected Output:

Enter first number 10
Enter second number 20
The result is 200

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

number1 = int(input("Enter first number "))
number2 = int(input("Enter second number"))

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

Question 2: Given a range of numbers. Iterate from o^th 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
0
1
3
5
7
9
11
13
15
17

def sumNum(num):
  previousNum=0
  for i in range(num):
    sum = previousNum + i
    print(sum)
    previousNum = i

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

Question 3: Accept string from the user and display only those characters which are present at an even index

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

Reference article for help:

• Python Input and Output

Expected Output:

Enter String  pynative
Orginal String is  pynative
Printing only even index chars
index[ 0 ] p
index[ 2 ] n
index[ 4 ] t
index[ 6 ] v

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

inputStr = input("Enter String ")
print("Orginal String is ", inputStr)

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

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

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

Expected Output:

Removing n number of chars
tive

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

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

Question 5: Given a list of ints, return True if first and last number of a list is same

Expected Output:

the first and last number of a list is same
result is True

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

numList = [10, 20, 30, 40, 10]

print("The first and last number of a list is same")
print("result is", isFirst_And_Last_Same(numList))

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

Expected Output:

Finding divisible of 5
10
20
55

def findDivisible(numberList):
  for num in numberList:
    if (num % 5 == 0):
      print(num)

numList = [10, 20, 33, 46, 55]
print("Finding divisible of 5 in a list")
findDivisible(numList)

Question 7: Return the number of times that the string “Emma” appears anywhere in the given string

Given string is “Emma is a good developer. Emma is also a writer” and output should be 2.

Reference article for help: Python range() function

Expected Output:

Emma appeared  2 times

def count_jhon(statement):
  count = 0
  for i in range(len(statement)-1):
    count += statement[i:i+4] == 'Emma'
  return count

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

Question 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")

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

Expected Output:

number = 121
Orignal and revers number is equal
True

def reverseCheck(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("orignal and revers number is equal")
print(reverseCheck(121))

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

Expected Output:

listOne = [10, 20, 23, 11, 17]
listTwo = [13, 43, 24, 36, 12]

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

def mergeList(listOne, listTwo):
  thirdList = []
  for num in listOne:
    if(num % 2 != 0):
      thirdList.append(num)
  for num in listTwo:
    if(num % 2 == 0):
      thirdList.append(num)
  return thirdList
    
print("Merged List is")
listOne = [10, 20, 23, 11, 17]
listTwo = [13, 43, 24, 36, 12]

print(mergeList(listOne, listTwo))
