Learn Python Basics in 7 Days: A Beginner’s Guide

Week 1: Python Basics (Days 1–7)

Welcome to your Python learning journey! In the first week, you’ll cover the fundamental concepts that form the building blocks of Python programming. Let’s break down the topics for each day:

---

Day 1: Introduction to Python

On the first day, you’ll install Python on your machine and set up your development environment. You’ll write your first Python program, “Hello, World!” and get introduced to basic syntax and comments.

• What to learn:
• Install Python from python.org.
• Set up your IDE or code editor (e.g., PyCharm, VS Code, or Jupyter Notebook).
• Write a simple program: print("Hello, World!").
• Learn about Python’s clean, easy-to-read syntax and how to add comments in code (# comment).

---

Day 2: Variables and Data Types

On Day 2, you will dive into Python’s data types and variables. You’ll understand how to work with integers, floats, strings, and booleans, and how to assign and manipulate variables.

• What to learn:
• Assign values to variables (e.g., x = 10).
• Explore data types: int, float, str, bool.
• Practice basic type conversion: int(), float(), str().

  x = 10  # integer
  name = "Alice"  # string
  height = 5.8  # float
  is_active = True  # boolean

---

Day 3: Control Flow with If Statements

Day 3 focuses on understanding how to control the flow of your program with conditional statements. You will learn how to use if, else, and elif to make decisions.

• What to learn:
• Use if, elif, and else for decision-making.
• Compare values using operators (==, !=, >, <).

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

---

Day 4: Loops in Python (For and While)

Learn how to automate repetitive tasks using loops. In Python, for and while loops help iterate through sequences like lists or perform actions repeatedly.

• What to learn:
• Write for loops to iterate through items in a list.
• Use while loops to repeat actions as long as a condition is true.

  for i in range(5):
      print(i)  # prints numbers from 0 to 4

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

---

Day 5: Functions

Day 5 is all about defining and calling functions in Python. Functions help you organize your code, making it reusable and more readable.

• What to learn:
• Define functions with def.
• Pass parameters and return values from functions.
• Understand the concept of local and global variables.

  def greet(name):
      return "Hello, " + name

  print(greet("Alice"))

---

Day 6: Lists and Tuples

On Day 6, you will learn about two of Python’s most important data structures: lists and tuples. These allow you to store collections of items.

• What to learn:
• Create, modify, and access elements in lists.
• Understand the difference between lists (mutable) and tuples (immutable).

  my_list = [1, 2, 3, 4]
  my_tuple = (1, 2, 3, 4)

---

Day 7: Dictionaries and Sets

On the final day of Week 1, you’ll get familiar with two more important data structures: dictionaries and sets.

• What to learn:
• Work with dictionaries (key-value pairs).
• Understand sets and their properties (unique and unordered).

  my_dict = {"name": "Alice", "age": 25}
  my_set = {1, 2, 3, 4}

---

Conclusion of Week 1

By the end of Week 1, you’ll have a solid understanding of Python’s basic syntax, variables, control flow, loops, functions, and core data structures like lists, dictionaries, and sets. You can now start building simple programs and begin practicing Python through coding exercises.

Next Steps

In Week 2, you will dive deeper into more advanced Python topics such as error handling, object-oriented programming (OOP), and file handling.
