Whether you’re new to coding or looking to sharpen your skills, engaging in practical exercises can significantly boost your programming abilities ejercicios python para practicar. Here are ten Python exercises designed to challenge beginners and help you improve your coding skills.
1. Hello, World!
Objective: Write a program that prints “Hello, World!” to the console.
Why: This classic exercise introduces you to the basic syntax of Python and the concept of outputting text.
Example Code:
pythonCopy codeprint("Hello, World!")
2. Basic Calculator
Objective: Create a simple calculator that can perform addition, subtraction, multiplication, and division.
Why: This exercise helps you understand user input, basic arithmetic operations, and conditional statements.
Example Code:
pythonCopy codedef calculator():
num1 = float(input("Enter first number: "))
num2 = float(input("Enter second number: "))
operation = input("Enter operation (+, -, *, /): ")
if operation == "+":
print(f"Result: {num1 + num2}")
elif operation == "-":
print(f"Result: {num1 - num2}")
elif operation == "*":
print(f"Result: {num1 * num2}")
elif operation == "/":
if num2 != 0:
print(f"Result: {num1 / num2}")
else:
print("Error: Division by zero")
else:
print("Invalid operation")
calculator()
3. Fibonacci Sequence
Objective: Generate the Fibonacci sequence up to a given number of terms.
Why: This exercise introduces loops and recursive functions, essential concepts in programming.
Example Code:
pythonCopy codedef fibonacci(n):
a, b = 0, 1
for _ in range(n):
print(a, end=' ')
a, b = b, a + b
num_terms = int(input("Enter the number of terms: "))
fibonacci(num_terms)
4. Palindrome Checker
Objective: Write a function to check if a given string is a palindrome (reads the same forwards and backwards).
Why: This exercise helps you practice string manipulation and logic implementation.
Example Code:
pythonCopy codedef is_palindrome(s):
return s == s[::-1]
word = input("Enter a word: ")
if is_palindrome(word):
print("It's a palindrome!")
else:
print("It's not a palindrome.")
5. Number Guessing Game
Objective: Create a game where the computer randomly selects a number, and the user has to guess it within a limited number of attempts.
Why: This exercise involves random number generation, loops, and conditionals.
Example Code:
pythonCopy codeimport random
def guessing_game():
number = random.randint(1, 100)
attempts = 0
while attempts < 10:
guess = int(input("Guess the number (1-100): "))
attempts += 1
if guess < number:
print("Too low!")
elif guess > number:
print("Too high!")
else:
print(f"Congratulations! You've guessed the number in {attempts} attempts.")
break
else:
print(f"Sorry, you've used all attempts. The number was {number}.")
guessing_game()
6. Simple Alarm Clock
Objective: Create a program that takes a time as input and prints a message when that time is reached.
Why: This exercise introduces handling time and scheduling in Python.
Example Code:
pythonCopy codeimport time
def alarm_clock(set_time):
while True:
current_time = time.strftime("%H:%M:%S")
if current_time == set_time:
print("Alarm ringing!")
break
time.sleep(1)
set_time = input("Enter the time for the alarm (HH:MM:SS): ")
alarm_clock(set_time)
7. List Operations
Objective: Implement functions to perform basic operations on lists, such as finding the maximum value, minimum value, and average.
Why: This exercise enhances your understanding of lists and basic statistical operations.
Example Code:
pythonCopy codedef list_operations(lst):
print(f"Maximum value: {max(lst)}")
print(f"Minimum value: {min(lst)}")
print(f"Average value: {sum(lst) / len(lst)}")
numbers = [int(x) for x in input("Enter numbers separated by spaces: ").split()]
list_operations(numbers)
8. Simple To-Do List
Objective: Create a simple to-do list application where you can add, remove, and view tasks.
Why: This exercise involves handling user input and managing a list of tasks.
Example Code:
pythonCopy codedef todo_list():
tasks = []
while True:
action = input("Enter 'add', 'remove', 'view', or 'quit': ").strip().lower()
if action == 'add':
task = input("Enter the task: ")
tasks.append(task)
elif action == 'remove':
task = input("Enter the task to remove: ")
if task in tasks:
tasks.remove(task)
else:
print("Task not found.")
elif action == 'view':
print("To-Do List:")
for i, task in enumerate(tasks, 1):
print(f"{i}. {task}")
elif action == 'quit':
break
else:
print("Invalid action.")
todo_list()
9. Prime Number Checker
Objective: Write a function to check if a given number is a prime number.
Why: This exercise involves understanding algorithms and number theory.
Example Code:
pythonCopy codedef is_prime(n):
if n <= 1:
return False
for i in range(2, int(n ** 0.5) + 1):
if n % i == 0:
return False
return True
number = int(input("Enter a number: "))
if is_prime(number):
print("It's a prime number!")
else:
print("It's not a prime number.")
10. Simple Text-Based Adventure Game
Objective: Create a basic text-based adventure game where the user can make choices that affect the outcome.
Why: This exercise helps you practice structuring a program and implementing decision-making.
Example Code:
pythonCopy codedef adventure_game():
print("You are in a dark forest. There are two paths ahead: left and right.")
choice = input("Do you want to go left or right? ").strip().lower()
if choice == 'left':
print("You find a treasure chest filled with gold!")
elif choice == 'right':
print("You encounter a wild animal and have to run back to safety.")
else:
print("Invalid choice. Please type 'left' or 'right'.")
adventure_game()
