Python Tutorial for Beginners - Learn Python in 5 Hours [FULL COURSE]

Introduction

This tutorial is designed to guide beginners through the fundamental concepts of Python programming, as covered in the comprehensive video course "Python Tutorial for Beginners - Learn Python in 5 Hours" by TechWorld with Nana. By following these steps, you will gain a solid understanding of Python and practical experience through hands-on projects.

Step 1: Install Python and Set Up Your Environment

1. Download Python:

   • Visit the official Python website to download the latest version of Python.

2. Install Python:

   • Run the installer.
   • Ensure you check the box that says "Add Python to PATH" during installation.

3. Install PyCharm:

   • Download PyCharm from JetBrains.
   • Use the discount code "PYCHARMFORDEVOPS" to try the Professional Edition for free for three months.

4. Set Up Your First Project:

   • Open PyCharm and create a new project.
   • Ensure your project interpreter is set to the Python version you installed.

Step 2: Write Your First Python Program

1. Create a new Python file:

   • Right-click on your project folder in PyCharm, select "New" and then "Python File".

2. Write a simple program:

   • Type the following code to print "Hello, World!" to the console:

     print("Hello, World!")
     

3. Run your program:

   • Right-click the Python file and select "Run" to see the output.

Step 3: Understand Basic Data Types

1. Strings:

   • Strings are sequences of characters. Example:

     name = "Alice"
     

2. Numbers:

   • Python supports integers and floats. Example:

     age = 30
     height = 5.7
     

3. Booleans:

   • Represents True or False values. Example:

     is_student = True
     

Step 4: Learn About Variables

1. Declare variables:

   • Assign values to variables with the equals sign. Example:

     x = 10
     y = 5
     

2. Use variables in calculations:

   • Example of a simple addition:

     sum = x + y
     print(sum)
     

Step 5: Functions and Scope

1. Define a function:

   • Use the def keyword to create a function. Example:

     def greet():
         print("Hello!")
     

2. Call the function:

   • Simply type the function name followed by parentheses:

     greet()
     

3. Understand scope:

   • Variables defined inside a function are local to that function.

Step 6: Accept User Input

1. Get input from the user:
   • Use the input() function to capture user input. Example:

     user_name = input("Enter your name: ")
     print("Hello, " + user_name)
     

Step 7: Control Structures

1. Conditionals:

   • Use if, elif, and else to control the flow of your program. Example:

     if age >= 18:
         print("You are an adult.")
     else:
         print("You are a minor.")
     

2. Loops:

   • Use a while loop for repeated execution based on a condition:

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

3. For loops with lists:

   • Iterate over a list using a for loop:

     fruits = ["apple", "banana", "cherry"]
     for fruit in fruits:
         print(fruit)
     

Step 8: Advanced Data Structures

1. Lists:

   • Create a list to store multiple items:

     numbers = [1, 2, 3, 4]
     

2. Sets:

   • Use sets for unique items:

     unique_numbers = {1, 2, 3}
     

3. Dictionaries:

   • Store key-value pairs:

     student = {"name": "Alice", "age": 21}
     

Step 9: Learn About Modules and Packages

1. Importing modules:

   • You can import built-in modules or your own:

     import math
     print(math.sqrt(16))
     

2. Creating your own module:

   • Save your functions in a .py file and import it in your main program.

Step 10: Build Projects

1. Countdown App:

   • Create a simple countdown timer using loops and input functions.

2. Automation with Python:

   • Work with spreadsheets using libraries like pandas.

3. API Requests:

   • Learn to make API requests using the requests library.

Conclusion

By following these steps, you have laid a strong foundation in Python programming. You have learned how to set up your environment, write basic programs, understand data types, utilize control structures, and build simple projects. As you progress, consider exploring more complex topics such as Object-Oriented Programming and working with external libraries. Keep practicing and happy coding!
