How to Stand Out in a Python Coding Interview & Python Interview Tips?


In this article, we will learn about Python Coding Interview questions with their relevant answers. Besides, we will provide you with extra tips and tricks to perform well in a Python Coding Interview Session. As we all already know, Python is a high-level programming language and it needs to be studied to perform specific virtual work projects.

It is a vast language and needs hands-on experience in order to be good at it. You will need the right amount of experience and live sessions to crack an interview because all a company asks for is someone fluent in this language. For this, you can either do an offline course for Python or take Python Programming Online Training to excel in this field.

Now, before jumping on to the questions and answers for an interview, let us go understand what Python actually is.

What is Python?

Python is a high-level programming language that includes libraries such as:

  • Matplotlib
  • SciPy
  • Scikit-Learn
  • NumPy
  • Lambda functions
  • Web Scraping
  • Pandas

Python is also object-oriented with dynamic semantics. Even if everyone suggests that it is interpreted and high-level, it is also easy to learn and simple syntax form. Its extensive standard library and interpreter are available in binary or source form of language.

For programmers, python might be their one true love because they generally tend to invest a major share of their time in doing or cracking python programs. It enhances the productivity factor and its debugging is also easy.

Python Interview Questions and Answers

The following questions and answers were prepared by Python developers and experts. This set of questions and answers will surely help you crack your next interview stage and you will be able to understand these easily if you have done any Python Programming Online Training.

What is the process of debugging a Python Program?

To debug a Python Program, we need to use this command:

1 $ python -m pdb

What is the process of converting a list into a string?

For changing a list into desired strings, we need to use the <“.join()> method. This method will join every element into a single element and then return it as a string.

For example –

dayname = [‘m’,’tu’,’w’,’th’,’fr’,’sa’,’su’]

listAsString = ‘ ‘.join(dayname)


How would you describe a <Yield> keyword in Python Programming?

The reason to use the <Yield> keyword in Python is to turn any given func() into a generator. In other words, we can also say that <yield> is used as a fundamental returning keyword.

Note: Yield is a return keyword, however, it will only give back a generator object. A function, in turn, is obliged to have more than one call to the <Yield> keyword.

For example –

def testgen(index):

dayname = [‘m’,’tu’,’w’,’th’,’fr’,’sa’,’su’]

yield dayname[index]

Yield dayname[index+1]

day = testgen(0)

print next(day), next(day)

What is the process of converting a list into a tuple?

To change the given list into tuples, we will need to use the Python <tuple()> function.

Note: It is not possible to change the list once after it is turned into a tuple (as it will then become immutable).

For example –

dayname = [‘m’,’tu’,’w’,’th’,’fr’,’sa’,’su’]

listAsTuple = tuple(dayname)


What do we use to count the occurrence of a particular element in a particular list?

To count an occurrence of an element in a list, we will have to use a <count()> function. This function helps us to count specific occurrences as shown below:

dayname = [‘su’,’m’,’tu’,’w’,’th’,’fr’,’su’,’m’,’m’]


What is the process of converting a list into a set?

In order to change a list into a set, we will have to use the <set()> function.

For example –

dayname = [‘su’,’m’,’tu’,’w’,’th’,’fr’,’sa’,’su’,’tu’]

listAsSet = set(dayname)


How do you describe the NumPy array?

As compared to the list in Python, we know that the NumPy arrays have higher flexibility. It enables written & read items to be more efficient and less time-consuming.

You can also create an Empty NumPy array. To do so, you can either import numpy (numpy.array([]) or numpy.empty (shape=(0,0))

What will be the output of this given code?

>> import array

>>> a = [1, 2, 3]

>>> print a[-3]

>>> print a[-2]

>>> print a[-1]

The output of this code will be:

3, 2, 1

How would you describe a Negative Index in Python?

There is a special feature of negative indexes in Lists and Arrays. Under this function, Python will read elements from the very end of any list of arrays. Whereas, on the other hand, the positive index will read the element from the very starting of a list or an array.

Tips to Stand Out in a Python Interview

All you have to do is know Python thoroughly. You should love Python in order to excel in this field. The right amount of devotion and hard work will lead to the heights of success. Stay confident in your interview and have a learning mindset.

Even if you don’t know any answer or are figuring out any outcome, stay focused and initiate learning it instead of dragging it and wasting the interviewer’s time. Mend your Python skills and solve existing confusion before the interview. Practice as much as you can and you are good to go!

How can a Decent Python Learning Course Benefit You?

One of the basic learning programs of Python is the Python Programming Online Training, which you can get anywhere except you will have to grab the best. You can find many online institutes offering relevant courses for Python and other programming languages. They discuss its libraries as well as its features in detail.

Python Programming Certification is also of huge importance if taken from a recognized and reliable institute. They have the means to let you master the core concepts of Python Programming, and learn under the guidance of exceptionally experienced professionals.


Learning Python Programming language or taking Pershing a Python Programming Online Training Course is a simple yet efficient task. Knowing Python will make you a high-level programmer and you can crack many codes. You can also create and evolve new methods of programming and achieve a lot more. Happy Python learning and all the best for your interview!
