The Why

We grow up being guided and taught by our seniors and mentors towards some milestone or goal. What I have learnt over the years is getting to know why I am doing something is more important than the deed itself. This is no different when it comes to Python programming. Have you asked yourself why you are learning or intending to learn Python, why now? The sooner one answers this question, the sooner the clarity and direction toward their goals.

Python is a programming language that has gained popularity over the years since its creation by the “benevolent dictator for life”, Guido Van Rossum. It is a language that is widely used due to its comparable simplicity and readability making it a preferable language to use for many software developers and companies alike.

2022 through to this year there have been numerous digital transformation s, yielding new revenue streams for companies and the Information Technology (IT) field and tapping into other industries. I am referring to the age of the Artificial Intelligence (AI) and this is also where Python comes into the subject. Currently, AI is booming and if you have been browsing through the internet, you may have come across some Python libraries such as PyTorch and TensorFlow being mentioned or referred to.

Python is being widely used by many companies for automation, data analysis, data visualization and for scientific research. If these few examples of use do not whet your Python coding appetite, then there is more in the following sections.

While you are learning to code in Python, factoring in your WHY will take you to grater heights towards your quest in programming. Some points to encourage to learn Python include:

• It is relatively easy to learn
• Python careers are in demand
• It has a large, mature, and supportive community
• There are lots of resources for learning (free and paid)
• Python has many libraries and frameworks supporting many usages

Concepts To Learn

When learning a new subject or technology, you want to and should start with the fundamentals before building on them. This is a good approach towards grasping the building blocks of the subject, in this case, Python. Some of the concepts that you should have a look at include:

• Data Structures: These include lists, dictionaries, sets and tuples. They really help in manipulating data and one gets to learn about when to use which data structure over the other.
• Modules and Functions: A module can be described as a Python file with .py extension and can be imported inside another Python program. A function is a block of code that runs when it is called, one can pass data (parameters) into a function.
• Object-Oriented Programming (OOP): Python is an OOP language which includes classes, objects, attributes and methods in its structure. Other concepts than you will learn in Python include inheritance, encapsulation and abstraction.
• Unit Testing: This concept can be foreign to beginners but it is important especially as one develops large Python projects and the whole importance of testing the working of different parts or features of a program (units).
• Error Handling and Debugging: A programmer’s life will inevitably involve errors. In reality, errors can be very helpful in locating logic problems and syntax errors in your code when writing programs. Errors that you are aware of should be handled or taken care of to ensure uninterrupted code execution. Any lines of code that include errors are handled by error handling before the code continues to run. It is important for anyone learning Python to put this into account.

Note that the list above is not limiting and that it can be extended. Always yearn to learn more by researching on the points mentioned.

Common Pitfalls To Avoid

Mistakes are part of the learning process and Python is not and exception to this. I started learning Python because I had to use it to run specific tasks and while I theoretically knew the tasks, I didn’t know how to write the code. In the process of learning up-to-date, I have come across various mistakes that even other programmers out there experience. Through consistent learning and coding, these mistakes are noticeable and an experienced Python engineer should be in a position to realize this during development and correct it. They include:

• Skipping the basics: For begnners, Python’s extensive ecosystem and abundance of libraries can be overwhelming. The fundamentals of Python programming, such as variables, data types, loops, and conditionals, must be covered first. Skipping these foundational concepts could cause confusion later.
• Ignoring Python documentation: Excellent official documentation for Python is a helpful learning tool. It offers thorough justifications, illustrations, and references to many modules and operations. When you have questions or need more information, don’t make the error of not consulting the documentation.
• Over engineering: You could be tempted to develop complicated code when you’re just starting out. However, beautiful and simple solutions are possible thanks to Python’s clarity and readability. Investigate Python’s built-in methods, libraries, and idiomatic patterns to avoid over-complicating your code.
• Neglecting error handling: Programming involves both errors and exceptions on a regular basis. To create robust, maintainable code, error handling is essential. Avoid ignoring error notifications and using catch-all exception handlers that don’t provide specialized treatment. Instead, become familiar with Python’s exception structure and employ the proper error-handling strategies.
• Copy-pasting code without understanding:
  It’s tempting to copy and paste code snippets that you find online into your projects. While using already existing code is okay, be sure you know what each line of code accomplishes. Blindly copying code can result in errors, security flaws, or problems with eventual maintenance and modification.
• Not seeking help: Never be afraid to ask for assistance when you’re stuck or running into problems. It’s a terrific idea to ask questions and seek advice from seasoned programmers via online forums, developer groups, and sites like Stack Overflow.
• Impostor syndrome: This is a common experience even in experienced programmers. It includes self doubt, avoiding opportunities, reluctance to share knowledge and fear of asking question just to mention a few. Recognizing and acknowledging these feelings is the first step in overcoming them. Building a supportive network, seeking mentorship, focusing on personal growth rather than comparisons, and celebrating achievements can help beginners combat imposter syndrome and develop confidence in their programming skills.

You may improve your learning process and advance your Python programming skills by avoiding these frequent errors. To advance slowly, keep in mind to practice frequently, ask questions, and seek feedback.

Tools to Use

Simple text editors are rarely used by developers when writing code. Utilizing Integrated Development Environments (IDEs) or a combination of two is significantly more practical. There are many other tools available for writing Python code, I’ll keep my focus on the three most well-known ones: PyCharm, VS Code, and Jupyter Notebook.

1. PyCharm — Developed by JetBrains, is a powerful and feature-rich IDE specifically designed for Python development. It offers advanced code analysis, debugging tools, intelligent code completion, and integration with version control systems. PyCharm is available in both a free Community Edition and a paid Professional Edition, which includes additional features such as web development support.
2. VSCode — Visual Studio Code (VS Code) is a lightweight and highly customizable code editor developed by Microsoft. It has gained popularity among Python developers due to its extensive ecosystem of extensions and plugins. With the Python extension, it provides features like linting, debugging, code snippets, and integration with popular Python frameworks.
3. Jupyter Notebook — Jupyter Notebook is an interactive coding environment that allows you to create and share documents containing code, visualizations, and explanatory text. It is particularly useful for data analysis, prototyping, and creating data-driven reports. JupyterLab is the next-generation interface for Jupyter Notebook, providing a more versatile and integrated environment.

These are examples of popular IDEs for Python development. It’s worth exploring multiple options and trying them out to see which one aligns best with your coding style, workflow, and project requirements.
