Irrespective of the number of programming languages a programmer learns, Python will remain as one of the most commonly used, popular programming languages in the industry. It is a hot choice for both beginners and established programmers. Setting up a career as a programmer seems like a popular course of action today, but interviewing for Python can be intimidating. This article brings to you the top 10 Python interview questions and answers that are recently most popular among industry hiring experts.
• What are the benefits of Python?
Ans. Python is a programming language with objects, modules, threads, and automatic memory management. Its benefits are quite well-known. It is simple and easy to use, portable, extensible, built-in structure, and also, it is open-source.
• What is pickling and unpickling?
Ans. The pickle model accepts any Python object and converts it into a string representation, and dumps it in a file by using the dump function. Whereas, the process of retrieving original Python objects from the stored string representation is called unpickling.
• How is Python interpreted?
Ans. Python is an interpreted language. The program runs directly from the source code. It directly converts the source code that is written by the programmer into an intermediate language, which is again translated into machine language that has to be executed.
• What are Pandas?
Ans. It is an open-source Python library that has a very risen set of data structures for data-based operations. Its unique features fit into every role of data operation, whether it is academics or complex business problems. Pandas can deal with several varieties of files and is one of the most important tools to have a grip on.
• How is memory managed in Python?
Ans. Python memory is managed by its private heap space. It is inaccessible to the programmer and the interpreter takes care of this Python private heap space. The allocation is done by the Python memory manager. The core API gives access to some tools for the programmer’s code. It also has an in-built garbage collector, which recycles all the unused memory and frees it to make more available space.
• What are the supported standard data types in Python?
Ans. The supported standard data types in Python include list, number, string, dictionary, and tuples.
• What is your understanding of Python?
Ans. Python is a highly comprehensive, interactive, and object-oriented scriptwriting language. It is specifically designed with the purpose of making the content highly readable among internet users. It makes use of various keywords in different languages other than punctuations. It also has lesser syntactical constructions like in other languages.
• What is the lambda function in Python?
Lambda is an anonymous function in Python that can accept any number of arguments and can have any number of parameters. However, it can only have a single statement or expression. Generally, it is used in situations that require an anonymous function in a short period.
• How are identity operators different from membership operators?
Ans. Unlike membership operators, identity operators compare the values to find out if they have the same value or not.
• What is meant by namespace?
Ans. A namespace refers to a naming system that is used to ensure that all the object names in a Python program are unique, to avoid any complexities. These namespaces are implemented as dictionaries with ‘name as key’ mapped to a corresponding value of the object.
