Fortunately, you can streamline the hiring process and save a great deal of time by partnering with Bridge.

  • Additionally, I utilized Docker Compose to manage multi-container applications, allowing us to easily orchestrate various services such as databases, caching systems, and message brokers.
  • This video on Python Interview Questions and Answers will help you prepare for Python interviews.
  • Both developers work within ecosystems rich in frameworks and libraries, facilitating faster application development.
  • This lets your interviewer know that you care about providing the most accurate response and demonstrate this through the use of active listening skills.

Regardless of representation, the `max` function can directly obtain the maximum element. For example, given a list `arr`, the expression `max(arr)` returns the largest element. Both functions and methods represent blocks of code in Python, methods are bound to objects, whereas functions are not. A class method, marked with the `@classmethod` decorator, takes a reference to the class, `cls`, as its first parameter. It can’t access instance-specific data, but it can access and modify class-level data.

How do you create an empty dictionary?

You can also create a generator function by replacing the return keyword with the yield keyword if you want. In Java, we get a .class file that contains the byte-code of the program we want to execute. Similarly, In Python, .pyc file contains all the byte-code of the python program that we want to execute. I have picked the 5 most frequently in this section and recently asked interview questions from advanced Python.

Memory management in Python uses reference counting, and the language’s syntax is more concise. A Java developer focuses on building applications using the Java language. Java Developers rely on a statically-typed language, work within the confines of the Java Virtual Machine (JVM), and adhere to the object-oriented principles that Java how to become a python developer emphasizes. Java developers handle large-scale enterprise applications, benefiting from Java’s robustness and cross-platform capabilities. Memory management in Java is automated through garbage collection, and this developer tends to work with verbose syntax. The `unittest` library provides a `Mock` class to create mock objects.

How would you sort a list of dictionaries by a specific key?

The function returns a new list with the numbers sorted in ascending order, when this function is called with a list of numbers. Use the function in your application by passing the list you want to sort. If you wish to sort the original list in-place, use the `sort` method of the list. You can customize class creation and modification by creating your own metaclass.

  • It is versatile, serving both beginners with high-level APIs and researchers with more granular control over model architectures.
  • Additionally, I integrated the database with the Django ORM, which allowed me to seamlessly interact with the data using Python.
  • Similarly, In Python, .pyc file contains all the byte-code of the python program that we want to execute.
  • Java developers develop enterprise applications, mobile applications, and big data systems.
  • It is worth mentioning that the open function in Python is a built-in function that returns a file object, which can be used as a context manager.

Python programming questions assess a developer’s expertise with the features, best practices, and challenges of specific tools. A developer’s dedication to leveraging Python’s extensive ecosystem and their competence in addressing intricate issues in specialized areas is showcased by familiarity with theses. In Python, we use range(0,10) to create a list in memory for 10 numbers.

What is the difference between `staticmethod`, `classmethod`, and instance methods in Python?

This question is meant to gauge your experience and familiarity with this process, as well as your knowledge of the libraries and tools available in Python for web scraping. Your answer will help the interviewer assess your capabilities and determine if you’re a good fit for the role. A shallow copy creates a new object while maintaining references to the original elements within the copied object. This means that if the original object contains mutable elements like lists or dictionaries, changes made to those elements will be reflected in both the original and the copied object. Shallow copies can be created using the copy() method from the copy module or by calling the copy() method on certain built-in data types like lists and dictionaries.

python developer interview questions

Data structures and algorithms are essential components of many Python applications. Study common data structures such as lists, dictionaries, and sets, and practice implementing algorithms such as sorting and searching. In this example, namespaces provide a method to identify and manage entities with similar names distinctly, thus avoiding confusion and conflicts. Similarly, in Python, namespaces prevent naming clashes and offer a structured approach to organizing variables, functions, classes, and other identifiers within a program. Educative-99 is a set of commonly asked questions asked in FAANG interviews to help candidates practice their coding skills.
