Students studying Engineering or completed their studies from an Engineering background will definitely know the importance of knowing programming languages. Especially, if you want to work in Top IT Companies then you have to know Programming Languages. Nowadays many students want to get a job in IT companies because there are lots of job opportunities available than other jobs. Also, Private Companies give high salary packages to their employees and career growth is fast. So many students want to start their careers in IT companies in different roles. But one thing is very important if you want to start tour career in IT companies then you should have strong knowledge of different programming languages. Like- Python, Java, C, C++, Web development, etc. In this article, we will mention some top Python interview questions to help students. Basic python interview questions and for experienced also.
But only for the students of this background but for anyone who wants to grow their career in IT companies then they should at least have minimum knowledge of programming. Among all the programming languages Python is one of the top Programming languages. In interviews, the recruiter asks questions from Python to check knowledge. So here we will mention important Python interview questions that can be asked in an interview.
What is Python? What are the advantages of Python?
It is a basic Python interview question. Python is a programming language with built-in objects, modules, threads, exceptions, and automatic memory management. Python is simple and easy to use, portable, extendable, with a built-in data structure, and open-source.
How we use memory in Python?
It is one of the important python interview questions. Python memory is managed by Python heap space. A private heap holds all Python objects and data structures. The allocation of Python heap space for Python Object is done by the Python memory manager. The core API provides access to some programming tools for programmers. Python also includes a built-in garbage collector that recycles all unused memory, frees it, and makes it available to the heap space.
What is the difference between by value and by reference in Python? python interview questions
In Python, everything is an object, and all variables are references to objects. The functions determine the reference values. As a result, you won’t be able to change the value of the references. If the item is modifiable you can change it.
List five advantages of using Python?
The following are five advantages of Python-
Python has a large standard library for most Internet platforms, such as email, HTML, and so on.
Python does not require manual memory management because the interpreter automatically allocates and frees memory for new variables.
The usage of square brackets makes it easier to read.
In addition, it is simple to learn.
What are some of Python’s applications?
It is a common python interview question. Every recruiter almost asks the freshers. Python is used in a variety of software domains. For example– Internet and Web Development, Playing games, Applications in science and computation, The development of language, likewise Applications for image processing and visual design, Development of enterprise and business apps, Computer operating systems, Desktop apps with a graphical user interface.
How do Django, Pyramid, and Flask differ from one other?- important Python interview questions
Many students remark this question as commonly asked in their python interview question. Flask is a “microframework” designed for small applications with straightforward needs. You don’t need to use external libraries in a flask. The flask is now ready for use.
Pyramids are used for big projects. It gives developers flexibility and allows them to use the correct tools for their projects. You can choose the database, URL structure, templating style, and more. Like Pyramid, we use Django for larger applications. It includes an ORM.
What is the difference between Break, Continue, and Pass statements in Python?
This question can be asked in most python interview questions students faced. These statements are known as loop control statements since they help to vary the execution phase from the typical flow.
Break statement in Python- This statement is used to end a loop or a statement and pass control to the next statement.
Python Continue- Rather than halting the iteration when a certain condition is met, this statement forces the execution of the following iteration.
Pass in Python- This statement helps the code to write syntactically and wants to skip the execution. We also consider it as a null operation.
What is the meaning of NumPy and SciPy in Python?- commonly asked Python interview questions
SciPy stands for Scientific Python, while NumPy stands for Numerical Python. In addition, NumPy is the basic library for defining arrays and solving elementary mathematical issues. But SciPy is used for other issues like numerical integration, optimization, and machine learning.
What is Python’s Tuple Matching?
Tuple matching is a method of grouping tuples in Python by matching the second member in each tuple. In python programming, it is accomplished by utilizing a dictionary and inspecting the second member in each tuple. In addition, We can create new tuples by combining parts of existing tuples.
What is the Python function enumerate()? – top asked python interview questions
Enumerate() is a built-in Python method that assigns an index to each item in an iterable object. It creates a loop on iterable objects while keeping track of the current item and returns the object in the enumerable form. The list() method can be used in a for loop to convert this object into a list.
What is the best way to convert a number to a string?
This is one of the most often asked python interview questions. The built-in str() function can be used. We can utilise additional built-in functions like oct() or hex() to get an octal or hexadecimal representation ().
Does Python have a main() function?
Yes, it does. It is executed automatically whenever we run a Python script. We may also utilize the if statement to overrule the natural flow of things.
In Python, what are “docstrings”? – important Python interview questions
Documentation strings, often known as docstrings, are multiline strings that are used to document a specific code segment. Docstrings should ideally define what a function or method does and should be included in triple quotes. Because they aren’t allocated to any variables, docstrings can be used as comments.
What is String Concatenation, Indexing, and Slicing?
Concatenation- It joins two Strings together.
Indexing- Which gets a single character from a String.
Slicing- Which gets several characters from a string at once.
What exactly is PEP 8?- python interview questions
It is one of the commonly asked Python interview questions. PEP 8 is a paper that assists us in providing rules on how to write Python code. Guido van Rossum, Barry Warsaw, and Nick Coghlan wrote it in 2001. It stands for Python Enhancement Proposal, and its main goal is to make Python code more readable and consistent.
What is Swapcase() function in Python?
This is also one of the important python interview questions. It’s a string function that changes all uppercase letters to lowercase letters and vice versa. Its purpose is to change the string’s case. This function duplicates the string, containing all of the characters in the swap case. It generates a small case string if the string is in lowercase, and vice versa. All non-alphabetic letters are ignored by default.
