Exercise 1: Calculate the multiplication and sum of two numbers
Given two integer numbers, return their product only if the product is equal to or lower than 1000. Otherwise, return their sum.
Given 1:
number1 = 20 number2 = 30
Expected Output:
The result is 600
Given 2:
number1 = 40 number2 = 30
Expected Output:
The result is 70
Refer:
Show Hint
- Create a function that will take two numbers as parameters
- Next, Inside a function, multiply two numbers and save their product in a
product
variable - Next, use the if condition to check if the
product >1000
. If yes, return theproduct
- Otherwise, use the else block to calculate the sum of two numbers and return it.
Show Solution
Exercise 2: Print the sum of the current number and the previous number
Write a program to iterate the first 10 numbers, and in each iteration, print the sum of the current and previous number.
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

Show Hint
- Create a variable called
previous_num
and assign it to 0 - Iterate the first 10 numbers one by one using for loop and range() function
- Next, display the current number (
i
), previous number, and the addition of both numbers in each iteration of the loop. Finally, change the value of the previous number to the current number (previous_num = i
).
Show Solution
Exercise 3: Print characters from a string that are present at an even index number
Write a program to accept a string from the user and display characters that are present at an even index number.
For example, str = "pynative"
so you should display ‘p’, ‘n’, ‘t’, ‘v’.
Expected Output:
Orginal String is pynative Printing only even index chars p n t v
Reference article for help: Python Input and Output
Show Hint
- Use the Python input() function to accept a string from a user.
- Calculate the length of the string using the
len()
function - Next, iterate each character of a string using for loop and range() function.
- Use
start = 0
, stop = len(s)-1, andstep =2
. the step is 2 because we want only even index numbers - In each iteration of a loop, use
s[i]
to print characters present at the current even index number
Show Solution
Solution 1:
Solution 2: Using list slicing
Exercise 4: Remove first n
characters from a string
Write a program to remove characters from a string starting from zero up to n
and return a new string.
For example:
remove_chars("pynative", 4)
so output must betive
. Here, we need to remove the first four characters from a string.remove_chars("pynative", 2)
so output must benative
. Here, we need to remove the first two characters from a string.
Note: n
must be less than the length of the string.
Show Hint
Use string slicing to get the substring. For example, to remove the first four characters and the remaining use s[4:]
.

Exercise 5: Check if the first and last number of a list is the same
Write a function to return True
if the first and last number of a given list is same. If numbers are different then return False
.
Given:
numbers_x = [10, 20, 30, 40, 10]
numbers_y = [75, 65, 35, 75, 30]
Code language: Python (python)
Expected Output:
Given list: [10, 20, 30, 40, 10] result is True numbers_y = [75, 65, 35, 75, 30] result is False
Show Solution
Exercise 6: Display numbers divisible by 5 from a list
Iterate the given list of numbers and print only those numbers which are divisible by 5
Expected Output:
Given list is [10, 20, 33, 46, 55] Divisible by 5 10 20 55

Exercise 7: Return the count of a given substring from a string
Write a program to find how many times substring “Emma” appears in the given string.
Given:
str_x = "Emma is good developer. Emma is a writer"
Code language: Python (python)
Expected Output:
Emma appeared 2 times
Show Hint
Use string method count()
.
Show Solution
Solution 1: Use the count()
method
Solution 2: Without string method
Exercise 8: Print the following pattern
1 2 2 3 3 3 4 4 4 4 5 5 5 5 5
Hint: Print Pattern using for loop
Show Solution
Exercise 9: Check Palindrome Number
Write a program to check if the given number is a palindrome number.
A palindrome number is a number that is the same after reverse. For example, 545, is the palindrome numbers
Expected Output:
original number 121 Yes. given number is palindrome number original number 125 No. given number is not palindrome number
Show Hint
- Reverse the given number and save it in a different variable
- Use the if condition to check if the original and reverse numbers are identical. If yes, return
True
.
Show Solution
Exercise 10: Create a new list from two list using the following condition
Create a new list from two list using the following condition
Given two list of numbers, write a program to create a new list such that the new list should contain odd numbers from the first list and even numbers from the second list.
Given:
list1 = [10, 20, 25, 30, 35]
list2 = [40, 45, 60, 75, 90]
Code language: Python (python)
Expected Output:
result list: [25, 35, 40, 60, 90]
Show Hint
- Create an empty list named
result_list
- Iterate the first list using a for loop
- In each iteration, check if the current number is odd number using
num % 2 != 0
formula. If the current number is an odd number, add it to the result list - Now, Iterate the first list using a loop.
- In each iteration, check if the current number is odd number using
num % 2 == 0
formula. If the current number is an even number, add it to the result list - Print the result list

Exercise 12: Calculate income tax for the given income by adhering to the rules below
Taxable Income | Rate (in %) |
---|---|
First $10,000 | 0 |
Next $10,000 | 10 |
The remaining | 20 |
Expected Output:
For example, suppose the taxable income is 45000, and the income tax payable is
10000*0% + 10000*10% + 25000*20% = $6000.

See: How two use nested loops in Python
Show Hint
- Create the outer for loop to iterate numbers from 1 to 10. So, the total number of iterations of the outer loop is 10.
- Create an inner loop to iterate 10 times.
- For each outer loop iteration, the inner loop will execute ten times.
- In the first iteration of the nested loop, the number is 1. In the next, it 2. and so on till 10.
- In each iteration of an inner loop, we calculated the multiplication of two numbers. (current outer number and current inner number)
