10 Python Beginner Exercises With Objectives (series 2)

This second series of Python beginner exercises introduces slightly more challenging tasks that help learners strengthen their fundamentals. Through practical problems like string manipulation, condition checks, loops, list processing, and simple algorithms, users can deepen their understanding while testing their ability to apply core Python concepts in real scenarios.

Exercise 1 — Temperature Converter (Celsius → Fahrenheit)

Objective: Practice arithmetic formulas and user input.

Task:
Ask the user for a temperature in Celsius and convert it to Fahrenheit.

c = float(input("Enter temperature in Celsius: "))
f = (c * 9/5) + 32
print("Fahrenheit:", f)

Exercise 2 — Maximum of Three Numbers

Objective: Use conditional statements to compare values.

Task:
Ask the user for three numbers and print the largest one.

a = float(input("Enter first number: "))
b = float(input("Enter second number: "))
c = float(input("Enter third number: "))

print("Largest number:", max(a, b, c))

Exercise 3 — Count Vowels in a Word

Objective: Work with loops, strings, and character checking.

Task:
Ask the user for a word and count how many vowels it contains.

word = input("Enter a word: ")
vowels = "aeiouAEIOU"
count = 0

for char in word:
    if char in vowels:
        count += 1

print("Vowel count:", count)

Exercise 4 — Reverse a String

Objective: Use slicing or loops to manipulate strings.

Task:
Write a program that reverses a word entered by the user.

word = input("Enter a word: ")
print("Reversed:", word[::-1])

Exercise 5 — Basic Password Strength Checker

Objective: Practice string conditions and logical operators.

Task:
Ask the user for a password and check:

if length < 6 → "Weak"
if length 6–10 → "Medium"
if length > 10 → "Strong"

password = input("Enter a password: ")

if len(password) < 6:
    print("Weak")
elif len(password) <= 10:
    print("Medium")
else:
    print("Strong")

Exercise 6 — Find the Smallest Number in a List

Objective: Work with lists and basic algorithms.

Task:
Given a list of numbers, print the smallest element.

numbers = [12, 3, 45, 7, 2, 9]
print("Smallest number:", min(numbers))

Exercise 7 — Count Down Timer

Objective: Use loops and decreasing counters.

Task:
Ask the user for a number and print a countdown to zero.

n = int(input("Enter a number: "))

for i in range(n, -1, -1):
    print(i)

Exercise 8 — Prime Number Checker

Objective: Use loops + conditions to implement logic.

Task:
Ask the user for a number and check whether it is prime.

num = int(input("Enter a number: "))

if num < 2:
    print("Not prime")
else:
    is_prime = True
    for i in range(2, int(num**0.5) + 1):
        if num % i == 0:
            is_prime = False
            break

    print("Prime" if is_prime else "Not prime")

Exercise 9 — Remove Duplicates from a List

Objective: Learn to use sets or logic to filter unique values.

Task:
Given a list with repeated values, print the list without duplicates.

numbers = [1, 2, 2, 3, 4, 4, 5]
unique = list(set(numbers))
print("Unique list:", unique)

Exercise 10 — Simple Bank Account Simulation

Objective: Combine variables, conditions, and loops.

Task:
Create a simple menu:

Deposit money
Withdraw money
Show balance
Exit

balance = 0

while True:
    print("\n1. Deposit")
    print("2. Withdraw")
    print("3. Show Balance")
    print("4. Exit")

    choice = input("Choose an option: ")

    if choice == "1":
        amount = float(input("Enter amount to deposit: "))
        balance += amount
    elif choice == "2":
        amount = float(input("Enter amount to withdraw: "))
        balance -= amount
    elif choice == "3":
        print("Balance:", balance)
    elif choice == "4":
        break
    else:
        print("Invalid option")
