Once the profiler is set up, I run the application with the profiler enabled, collecting data on its performance. After gathering sufficient data, I analyze the results, focusing on functions with high execution how to become a python developer times or excessive calls. Next, I investigate these areas further, looking for inefficient algorithms, unnecessary computations, or suboptimal data structures that may be causing the slowdowns.
In this article, we have seen commonly asked interview questions for a python developer. These questions along with regular problem practice sessions will help you crack any python based interviews. Over the years, python has gained a lot of popularity amongst the developer’s community due to its simplicity and ability to support powerful computations. Due to this, the demand for good python developers is ever-growing. Nevertheless, to mention, the perks of being a python developer are really good.
Python Automation Interview Questions and Answers for Experienced
Additionally, I’d consider leveraging libraries like NumPy or Pandas for efficient data manipulation and computation. If necessary, I might also explore parallelization with multiprocessing or multithreading to take advantage of multiple CPU cores. Optimizing code performance is an essential skill for developers.
- Yes, it is possible if the base class is instantiated by other child classes or if the base class is a static method.
- Whereas, unpickling is the conversion of binary form data to python objects.
- Thankfully, learning how to use Python during coding interviews can help you understand the language more deeply, which will pay dividends during day-to-day development.
- This method is highly efficient and even if this method feels less efficient, then the data should be represented in a more efficient format such as CSV etc.
- Transformations on partitioned data run quicker since each partition’s transformations are executed in parallel.
Functions can be passed as parameters to other functions because they are objects. Higher-order functions are functions that can take other functions as arguments. Python is one of the most widely-used and popular programming languages, was developed by Guido van Rossum and released first on February 20, 1991.

The exponential growth of AI is reshaping the landscape of many industries, including software engineering. Developers got a powerful AI-helper https://remotemode.net/ ready to write code, interpret… Looking for new ways to increase conversions, enhance customer engagement, and automate routine tasks?
The self variable in the init method refers to the newly created object while in other methods, it refers to the object whose method was called. It is a good Python coding interview question to check the basic knowledge of tools and bug checks. For some people, it is important to control the details to make sure that the hire is perfect. If you are this kind of person, asking interview questions for a senior Python developer yourself can satisfy your desire for controlling everything. Once the virtual environment is created, I activate it by running the appropriate script depending on the operating system. For example, on Windows, I would use my_virtual_env\Scripts\activate.bat, while on Unix-based systems, I’d use source my_virtual_env/bin/activate.
