What the Free PDF Guides Cover
Both of the free PDF guides that we mentioned cover the basics of Python programming in a clear and concise way. They start with an introduction to Python and its features, such as its syntax, indentation, comments, and interactive mode. They then explain how to install Python on your computer and how to run your first program.
After that, they teach you how to work with different data types in Python, such as numbers, strings, booleans, lists, tuples, dictionaries, and sets. They show you how to create, manipulate, and access these data types using various operators and methods. They also teach you how to use built-in functions and modules to perform common tasks with data types.
Next, they teach you how to control the flow of your program using conditional statements, loops, and functions. They show you how to write if-else statements, for loops, while loops, break and continue statements, and function definitions and calls. They also teach you how to use parameters, arguments, return values, scope, recursion, and lambda functions.
Then, they teach you how to use object-oriented programming in Python using classes and objects. They show you how to define classes and create objects from them. They also teach you how to use inheritance, polymorphism, encapsulation, abstraction, and special methods.
Finally, they teach you how to work with files and exceptions in Python. They show you how to open, read, write, and close files using different modes and methods. They also teach you how to handle errors and exceptions using try-except-finally blocks and raise statements.
How to Learn Python Faster and Easier
Learning Python in 21 days is possible, but it requires dedication and practice. You need to spend at least an hour or two every day reading the PDF guide and doing the exercises. You also need to review what you have learned and apply it to real-world problems. However, there are some tips and resources that can help you learn Python faster and easier. Here are some of them:
Use an online Python interpreter or a code editor to run your code and see the results instantly. This will help you debug your code and understand how it works. Some examples of online Python interpreters are Repl.it, Trinket, and CodeSkulptor. Some examples of code editors are Visual Studio Code, PyCharm, and Atom.
Join an online Python community and ask questions, share your code, and get feedback from other learners and experts. This will help you learn from others and improve your skills. Some examples of online Python communities are Stack Overflow, Reddit, and Discord.
Watch online Python tutorials and courses that explain the concepts and show you how to code in a visual and interactive way. This will help you learn faster and retain more information. Some examples of online Python tutorials and courses are YouTube, Coursera, and Udemy.
Read online Python blogs and books that provide more insights and tips on Python programming. This will help you deepen your knowledge and learn new tricks. Some examples of online Python blogs and books are Real Python, Python for Everybody, and Automate the Boring Stuff with Python.
What You Can Do with Python After 21 Days
After learning the basics of Python in 21 days, you will be able to write simple programs that can perform various tasks. You will also be able to read and understand other people's code and modify it to suit your needs. However, this is just the beginning of your Python journey. There is still a lot more to learn and explore with this amazing language.
Python has many applications and domains that you can use it for. You can use it for web development, data science, machine learning, artificial intelligence, game development, and more. You can also use it for personal projects, hobbies, or fun. For example, you can use it to create a web app, analyze data, build a chatbot, make a game, or automate tasks.
To learn more about these applications and domains, you need to learn some additional libraries and frameworks that extend the functionality of Python. These are packages of code that provide specific features and tools for different purposes. For example, you can use Flask or Django for web development, NumPy or Pandas for data science, TensorFlow or PyTorch for machine learning, PyGame or Arcade for game development, and so on.
You can find these libraries and frameworks online and install them using pip , which is a tool that comes with Python. You can also find online tutorials and courses that teach you how to use them effectively. By learning these libraries and frameworks, you will be able to create more complex and advanced programs with Python.
How to Review and Apply What You Have Learned
Learning Python in 21 days is not enough if you don't review and apply what you have learned. You need to reinforce your memory and practice your skills by doing some exercises and projects. This will help you consolidate your knowledge and improve your confidence. Here are some ways to review and apply what you have learned:
Do the exercises and quizzes that are included in the PDF guides. These will help you check your understanding and test your knowledge. You can also find more exercises and quizzes online, such as on GeeksforGeeks, W3Schools, and HackerRank.
Do some mini-projects that are related to the topics that you have learned. These will help you apply your skills and solve real-world problems. You can also find some project ideas online, such as on Python Project Ideas, DataFlair, and UpGrad.
Do some challenges and competitions that are based on Python programming. These will help you challenge yourself and compete with other programmers. You can also find some challenges and competitions online, such as on CodeChef, Kaggle, and Codewars.
How to Continue Your Python Journey After 21 Days
Learning Python in 21 days is a great achievement, but it is not the end of your Python journey. There is always more to learn and explore with this language. You need to keep learning and updating your skills to stay relevant and competitive in the market. Here are some ways to continue your Python journey after 21 days:
Learn some advanced topics of Python that are not covered in the PDF guides. These include topics such as generators, decorators, comprehensions, iterators, coroutines, concurrency, metaclasses, and more. You can find some online tutorials and courses that teach these topics, such as on Real Python, Educative, and Pluralsight.
