During Installation [IMPORTANT]: Double-click the .msi file to start the installation process. When asked for the destination folder, you can leave the default path as it is to install Redis. But, make sure to check the box that says “Add the installation folder to the PATH environment variable”.
Verify Redis Service: Make sure Redis services are running by running services.msc (CTRL+R, type services.msc)
If the Redis is not showing running status, right-click on Redis and click Start.
Verify Redis Installation: After installation, open your command prompt and run redis-server. If Redis is running correctly, it will start the Redis server.
And you can also run redis-cli ping If Redis is running correctly, it will return PONG.
This will ensure that the Redis is successfully installed on your computer.
POSSIBLE ISSUES AND WARNINGS
Port already in use: In case the port 6379 is already in use, you may get the warning something like below.
In this case, run below commands to see the PID and kill it.
netstat -ano | findstr :6379 To see which process is running on port 6379.
taskkill /F /PID 15916 Note: Here 15916 is the PID received in above command. Run this command as an Administrator.
Once the process is killed, make sure the Redis service is running in services.msc and run the command redis-server

Intro – Effective Debugging Techniques for Python Developers
Debugging Python with ease! Investigate key methods for quickly finding and correcting errors in your code.
Every developer must learn the art of debugging. Dealing with errors is an inevitable aspect of the programming process, whether you’re a novice or a seasoned Python developer. This thorough book will walk you through key debugging techniques that will make it easier for you to locate and address problems in your Python code. You will be prepared to handle even the most challenging bugs in your projects by the time you finish reading this article.
Understanding the Debugger
Let’s familiarise ourselves with the debugger first before delving into specific debugging methods. With the help of the built-in debugger module pdb (Python Debugger), which is included with Python, you may step through your programme line by line, analyse variables, and set breakpoints in your code.
Whenever you wish to set a breakpoint to begin debugging, just add the following line:
import pdb; pdb.set_trace()
You will be put into the interactive debugger console when your code execution reaches this stage, at which point it will pause.
1. Printing Statements: Your First Line of Defense
Using print statements wisely is one of the simplest yet most powerful debugging strategies. You can learn more about the flow of your programme and the status of your variables by publishing variable values or messages at different locations throughout your code. This is very useful for pinpointing potential problem areas.
For example:
def divide(a, b): print(f'Dividing {a} by {b}') result = a / b print(f'Result: {result}') return result
2. Debugging with pdb
A robust collection of tools for debugging your Python code is offered by the built-in pdb module. The following are some crucial pdb commands:
n (next): Execute the current line and stop at the next line.
c (continue): Continue execution until the next breakpoint or until the program finishes.
q (quit): Exit the debugger and the program.
p (print): Print the value of a variable.
b (break): Set a breakpoint at a specific line.
s (step): Step into a function.
r (return): Continue execution until the current function returns.
Here’s an example of using pdb:
import pdb
def divide(a, b):
result = a / b
pdb.set_trace() # Set a breakpoint
return result
3. Using Assertions for Validation
Statements that affirm a particular condition to be true are known as assertions. They are incredibly useful for verifying your code’s assumptions. When an assertion fails, an AssertionError is raised, telling you about the unexpected circumstance.
def divide(a, b): assert b != 0, "Division by zero is not allowed" result = a / b return result
4. Exception Handling
You can handle issues that may arise while your code is running by using exception handling. You can manage exceptions using ‘try’ and ‘except’ blocks to capture them and keep your program from crashing.
def divide(a, b): try: result = a / b except ZeroDivisionError: print("Division by zero is not allowed") result = None return result
Conclusion
Conclusion
A essential skill for any Python coder is debugging. You can more effectively find and solve errors in your code by mastering these techniques and getting to know debugging tools like pdb. Remember that debugging involves more than just identifying and correcting issues; it also entails learning more about your code and improving your programming skills. So, embrace the debugging process and don’t let the odd issue get you down; it’s all a part of the process of improving as a developer.
Coding is fun! Each bug you resolve as you navigate the software development industry represents a step in your progress as a knowledgeable and tenacious programmer.
When it comes to choosing a Python web framework, two popular options are Django and Flask. While both frameworks have their strengths and use cases, there are some key differences that developers should consider. In this post, we will explore the differences between Django and Flask and discuss why you might choose Django over Flask for your web development projects.
1. Micro vs “Batteries-Included” Framework:
Flask is a lightweight, microframework that provides only basic functionality such as URL routing, templates, cookies, and a development server. It follows a minimalist approach, allowing developers to choose and add the components they need for their specific project.
Django, on the other hand, is a full-featured “batteries-included” framework that comes with almost every feature a website will need out of the box. It includes features like database connections, security, forms, and a powerful user admin. Django aims to provide a complete solution for web development, reducing the need for developers to search for and integrate external libraries.
2. Development Flexibility:
Flask provides fine-grained control and allows developers to decide how they want to implement things. It has no restrictions and allows the use of external libraries and add-ons as needed. This flexibility makes it a popular choice for developers who want more control over the components they use, such as databases and third-party tools.
Django, on the other hand, comes with its own set of modules and built-in features, providing a more opinionated approach and limiting the flexibility to experiment and control. While this may restrict some flexibility, it also ensures a consistent and standardized development experience. Django’s built-in features are designed to work well together, reducing the need for developers to make decisions about which components to use.
3. Learning Curve:
Flask has a relatively low learning curve. Its simplicity and minimalistic approach make it easier for beginners to grasp and understand. Flask’s documentation is well-organized and beginner-friendly, making it easier to get started with the framework.
Django has a steeper learning curve due to its extensive functionality and larger codebase. It may take more time to master Django, especially for those new to web development. However, Django’s comprehensive documentation and large community support make it easier to find resources and assistance when learning the framework.
4. Use Cases
Flask is well-suited for small to medium-sized projects, where simplicity, flexibility, and fine-grained control are desired. It is often used for building APIs, prototypes, or adding web functionality to existing codebases. Flask’s lightweight nature and flexibility make it a popular choice for developers who prefer to have more control over the components they use.
Django excels in developing large and complex web applications, such as news sites, e-stores, or blogs. Its “batteries-included” approach, robust features, and comprehensive functionality make it an excellent choice for projects that require scalability and maintainability. Django’s built-in features, such as the ORM (Object-Relational Mapping) and the admin interface, make it easier to handle complex database operations and manage content.
Conclusion
Both Django and Flask are popular Python web frameworks with their own strengths and use cases.
Flask provides simplicity, flexibility, and fine-grained control, making it a great choice for small to medium-sized projects where developers want more control over the components they use. It is often used for building APIs, prototypes, or adding web functionality to existing codebases.
Django, on the other hand, offers extensive functionality, a robust ecosystem, and a streamlined development experience. It is well-suited for developing large and complex web applications that require scalability and maintainability. Django’s “batteries-included” approach and comprehensive features make it an excellent choice for projects that need a complete solution out of the box.
When choosing between Django and Flask, consider the scope and complexity of your project, your level of experience, and the specific requirements of your application. Flask is a good fit for those who prefer simplicity, flexibility, and fine-grained control, while Django is ideal for those who prioritize a comprehensive feature set, scalability, and maintainability.
Ultimately, the decision should be based on your development goals and the trade-offs you are willing to make in terms of simplicity, flexibility, and development speed.
