Curso Python para Iniciantes

Introduction

This tutorial will guide you through the basics of programming in Python, tailored specifically for beginners. Python is a versatile language widely used in various fields such as automation, data analysis, website development, and app creation. This step-by-step guide will provide you with the foundational knowledge and practical skills needed to start coding in Python.

Step 1: Understand the Importance of Python

• Python is highly ranked among programming languages, making it a valuable skill in the job market.
• Its simplicity and readability make it an ideal choice for beginners.
• Python's applications are vast, including:
  • Task automation
  • Data analysis
  • Web development
  • Application development

Step 2: Set Up Your Development Environment

• Download and install Visual Studio Code (VSCode).
• Install Python from the official Python website.
• Configure VSCode to use Python:
  • Open VSCode.
  • Install the Python extension for VSCode.
  • Ensure Python is added to your system PATH.

Step 3: Write Your First Python Program

• Open VSCode and create a new file with a .py extension (e.g., hello.py).
• Write the following code to print a message:

  print("Hello, World!")
  

• Run the program by navigating to the terminal in VSCode and typing:

  python hello.py
  

Step 4: Learn Basic Programming Concepts

• Understand programming as a sequence of instructions.
• Familiarize yourself with the print() function to display output.

Step 5: Work with Variables

• Declare variables in Python using simple assignment:

  age = 25
  name = "John"
  

• Use variables to store and manipulate data.

Step 6: Explore Variable Types

• Learn about different data types in Python:
  • Integers
  • Floats
  • Strings
  • Booleans

Step 7: Perform Basic Operations

• Practice arithmetic operations:

  sum = 10 + 5
  difference = 10 - 5
  product = 10 * 5
  division = 10 / 5
  

• Use Python to perform calculations and store results in variables.

Step 8: Manipulate Strings

• Understand string operations, such as:
  • Concatenation: greeting = "Hello " + "World"
  • Repetition: repeat = "Hello " * 3
• Use string methods to modify text.

Step 9: Get User Input

• Use the input() function to receive input from users:

  user_name = input("What is your name? ")
  print("Hello, " + user_name)
  

Step 10: Understand Lists

• Create and manipulate lists in Python:

  fruits = ["apple", "banana", "cherry"]
  print(fruits[0])  # Access the first item
  

• Learn to use list methods like append(), remove(), and sort().

Step 11: Implement Conditional Statements

• Use if-else statements for decision-making:

  if age >= 18:
      print("Adult")
  else:
      print("Minor")
  

Step 12: Work with Dictionaries

• Understand how to use dictionaries for key-value pairs:

  person = {"name": "John", "age": 25}
  print(person["name"])
  

Step 13: Use Loops

• Learn about loops for repetitive tasks:
  • For loop:

    for fruit in fruits:
        print(fruit)
    

  • While loop:

    count = 0
    while count < 5:
        print(count)
        count += 1
    

Step 14: Define Functions

• Create reusable blocks of code with functions:

  def greet(name):
      print("Hello, " + name)
  
  greet("Alice")
  

Step 15: Explore Tuples

• Understand tuples as immutable sequences:

  coordinates = (10, 20)
  

Step 16: Read Files

• Use Python to read data from files:

  with open('file.txt', 'r') as file:
      content = file.read()
      print(content)
  

Step 17: Use Modules

• Import libraries to extend Python's capabilities:

  import math
  print(math.sqrt(16))
