Also, the best Python programmers have to plan to face an interview. They could quickly catch up with the competition. But, those who have just started studying it is a little difficult to crack in Python Programming Interview Questions.
Additionally, What After College- helps beginner Python learners achieve in their employment in Python. That is why we are posting an interesting and insightful collection of Python Programming Interview Questions.
Moreover, wac.co.in provides Python Programming Interview Questions is the one-stop tool from which to strengthen your interview preparation.
Top Python Programming Interview Questions
Firstly, The reason we share these interview questions is that you can revisit all of your basic concepts.
Secondly, The interviewer will surely check your understanding of Python Fundamentals, as you’re a beginner. Let’s begin to discover the basic Python Programming Interview Questions.
1. What is Python? What are the key features of Python?
Of course, This is the most repeated basic Python Programming Interview Question
- Python is a programming language of high quality, interpreted, general-purpose. And also, the general-purpose language it uses the right tools/libraries to construct almost any form of application.
- In addition, python supports objects, modules, threads, exception handling. And also, automated memory management that helps to solve these problems by modeling real-world issues and building applications.
2. What is PEP 8?
- PEP refers to a Python Enhancement Proposal. A PEP is an official design document that has the Python Community defines a new function for Python.
- PEP 8 is particularly important in that it documents the Python Code style guidelines. Apparently contributing to the open-source Python community needs you to honestly and strictly follow these design guidelines.
3. What are the lists and tuples?
This is one of the important Python Programming Interview Questions Python’s most flexible, useful data forms are lists and tuples, perhaps. Virtually any nontrivial Python program you’ll find them.
- In short, a list is a set of arbitrary objects, very similar but more versatile to an array in many other programming languages.
- In Python, lists describe in enclosing a comma-separated object sequence into square brackets[].
- Tuples are in all respects similar to lists, except for the following properties: tuples described by enclosing the elements in parentheses() rather than square brackets[].
- Tuples are unchangeable.
4. What is slicing in Python?
This is the most important and it may come as Python Programming Interview Question
- Slicing is a technique that enables only a portion of a list, tuple, or string to retrieve. Slicing allows clear, simple, and legible code writing.
- They can also change or remove objects from mutable sequences like lists. Slices can also extend to third-party objects such as NumPy arrays, as well as data frames and Pandas series.
5. What is the “pass” keyword?
In Python, the keyword “pass” is a no-operation expression. It signifies there is no need for intervention. It is a dummy place holder when it is necessary to fulfill a syntactic requirement of a certain programming element without assigning any operation.
for num in range(1,9):
if num==5:
pass
else:
print ("Num = {} ".format(num))
Output:
Num = 1
Num = 2
Num = 3
Num = 4
Num = 6
Num = 7
Num = 86. What is pickling and unpickling?
This is the most repeated basic Python Programming Interview Question
- Pickling module accepts and transforms any Python object into a string representation and dumps it into a file using the dump function.
- While unpickling the method of recalling original Python objects from the representation of the stored string.
7. Is Python allow arguments Pass by Value or Pass by Reference?
This is the most repeated basic Python Programming Interview Question
- Python uses a mechanism known as “Call-by-Object,” sometimes also known as “Call by Object Reference” or “Call by Sharing” If you pass into a function immutable arguments such as integers, strings or tuples, the passing acts like Call-by-value. If we pass mutable arguments it is different.
- In the Python language, all parameters (arguments) transfers by reference. It means that if you change what a parameter within a function refers to, the change also reflects back in the calling function.
8. Explain docstrings in Python?
- Python documentation strings (or docstrings) provide a simple way for Python modules, functions, classes, and methods to connect documentation with. Contrary to traditional discourse on source code, the docstring will explain what the feature does, not how.
- Those docstrings are in triple quotations. They should not allocate to any attribute and thus serve the function of comments at times as well.
9. What is help() and dir() function in Python?
- Both functions Help() and dir() are accessible from the Python Interpreter and to view a compiled dump of built-in functions.
- Help()function: The help()function is to show the documentation string and also allows you to see the support associated with the modules, keywords, attributes, etc.
- Dir()function: the dir()function is usage is to show the symbols identified.
10. Why do we need a break and continue in Python?
Additionally, In Python, statements that break and continue can alter the flow of a normal loop. Loops iterate over a code block until the test expression is incorrect, but often we want to end the current iteration or even the whole loop without testing the test expression.
These are the basic Python Programming Interview Questions.
