Its importance lies in the fact that it allows each new key to be given a default value based on the type of dictionary being created.

  • Dictionary comprehension is a concise way to create dictionaries from iterable sources.
  • In Python 2, there are separate string types for ASCII (str) and Unicode (unicode).
  • Developers can interact with databases using Python objects instead of writing raw SQL queries.
  • These techniques provide flexible means to modify arrays, adapting them to specific programming needs.

Python coding interview questions encompass foundational knowledge, hands-on coding abilities, and conceptual understanding of Python’s principles and design philosophies. Security is a top priority in software development, and interviewers want to make sure you’re aware of potential vulnerabilities and how to safeguard against them. As a Python developer, demonstrating your knowledge of secure coding practices and your ability to implement those practices within your projects is essential. This question helps interviewers understand your level of awareness and diligence when it comes to security in software development. Once the profiler is set up, I run the application with the profiler enabled, collecting data on its performance.
