Top 15 Advanced Python Interview Questions and Answers

The result is printed using the .numpy() method to convert the tensor to a NumPy array for easy visualization. In addition to solving these questions, prepare by training additional models and staying informed about current machine learning trends. Provide an example function that takes two DataFrames and a key column, and returns a merged DataFrame based on that key. The example illustrates how an array of length 1 (array2) is ‘stretched’ to match the size of array1 for multiplication, demonstrating the utility and power of broadcasting in NumPy. Rather than making copies, slicing creates a view, meaning the subarray shares data with the original array. Reshaping provides a new view on the same data, so it’s memory efficient as the data is not duplicated.

• The platypus is a mammal, though it lacks a trait common to the vast majority of other mammals.
• Whether you’re applying as a fresher or an experienced professional, the selection process is designed to evaluate technical knowledge, problem-solving abilities, and communication skills.
• Threading — multiple threads share the same memory space and GIL.
• All 3 artifacts (screenshots, videos, traces) live under use in the config.
• You use a sliding window with a set, move the right pointer adding characters, if a character repeats you move the left pointer and remove characters until it becomes unique again, and keep track of the max length seen so far.

The threads not having the GIL lock goes into the waiting state and resumes execution only when it acquires the lock. The process repeats and the GIL are used by different threads alternatively until the threads have completed their execution. When the I/O operations are done, thread 1 releases the acquired GIL which is then taken up by the second thread. GIL helps in achieving multitasking (and not parallel computing). Python provides a module called random using which we can generate random numbers.
As other websites, there are rules so that the password gets complex and none can predict the password for another. You told your friend John that you don’t know the addition of complex numbers, so John will write a program, which you can write in order to get the results of addition. Problem Statement – The math assignment says you will be given numbers, mostly with imaginary additions, that means complex numbers, and you need to add them and tell the answer in your answer script.
With features like auto-waiting, capturing screenshots, and generating PDFs, Playwright streamlines the testing process and enhances the reliability of web application performance.

This will not only enhance your technical skills but also showcase your ability to deliver tangible results.

Master All the Skills Accenture Looks For

When we talk about lists and tuples in Python, we’re essentially discussing ordered collections of items. A perennial favorite question revolves around the distinction between mutable and immutable types, often focusing on the classic comparison of lists versus tuples. Python offers a rich set of built-in data types and structures, and knowing them inside out is crucial. Career Story brings your roles, projects and skills together for drafting. Keep focused unit checks and add an integration check against the actual interface where practical. https://uvik.io/ Accenture evaluates candidates on these technical and analytical skills.
