Python is an open-source, versatile, robust, and user-friendly general-purpose programming language. Python is now the most essential language if you want to excel in the IT sector, especially now that Big Data and Analytics are the standards, you need to learn to code in Python language. But, just like any job, getting through the interview is about half the battle. We’ve sought together 15 of the most frequently asked Python interview questions to help you through your next Python interview. Now let us look for some of the most common and important Python language interview questions as well as answers.
Is Python Suitable for Both Web Client and Web Server Programming? Which One Is Most Appropriate for Python?
Python is ideal for developing web server-side applications because of its extensive collection of features for constructing business logic, databases connections, web server hosting, and so on. Python, on the other hand, can be utilised as a web client-side application that requires some conversions for a browser to understand the logic.
In Python, What Is Pip Software?
PIP refers to Python Installer Package, and it’s a utility that makes installing Python modules effortless. It is a command-line utility that explores the Internet seeking packages and installs them all without requiring user input.
What Is the Purpose of the __init__()?
_init_() is a method that is called whenever a class’s object is created, so it enables the class to categorize its attributes. In C++, this corresponds to the function Object() idea.
What’s a “Dynamically Typed Language”?
What Is the Best Way to Create Client-Side Gui Applications in Python?
To develop GUI-based applications, Python is combined with the standard library “Tkinter.” The Tkinter library includes several widgets that could produce and manage widget-specific events.
How Are a Tuple and a List Different?
The group of objects is stored in a list or a tuple. The major notable difference between a list and a tuple is that a list is a mutable object however, a tuple is an immutable object.

How Are .py and .pyc Files Different From Each Other?
The .py files contain source files of python, besides .pyc files, which are just the Python compiler’s produced bytecode files.
Explain Try, Except, Raise, and Finally
Python implements try, except, and finally blocks to handle errors. The try block is meant to run the function until an error is encountered. To accept control, we use the except block, which will get control over all errors, and otherwise, we may use a user-defined exception handling block for different types of errors. The instruction is forwarded to the relevant and appropriate except block. The final block gets used in every circumstance. Raise is just a command that allows you to generate your own exceptions.
What Is Negative Indexing?
The index can be used to find a specific element inside a list. The list’s normal indexing begins at 0.
Negative indexing is often used to access elements within lists in the very same way as normal indexing is. Negative indexing, on the other hand, enables us to retrieve the index out from the very end of the list. The negative index starts at -1 and it continues to go up, like -2, -3, -4, etc., until the list is finished.
In Python, What Is Slicing?
From a sequential data type, slicing is utilized to retrieve the subarray. Depending on the parameters we provide, it delivers data from sequential data types. It returns a data type that is the same as the data source type.
Three arguments are accepted under slicing. The start index, end index, and increment step are the three. For slicing, variable[start:end:step] is the syntax. Slicing does not require arguments. If you use an empty colon (:), the outcome will be the whole data set.
What Is Inheritance in Python?
Because Python is an object-oriented programming language, classes in Python can inherit attributes from other classes. This is called inheritance. Inheritance provides the characteristic of code reusability. The class being inherited is usually referred to as a superclass and otherwise parent class, while the class inheriting the superclass is referred to as a derived and perhaps even child class. Python identifies the following types of inheritance:
- Whenever a class inherits just one superclass, it is known as single inheritance.
- Whenever a class inherits from numerous superclasses, it is known as multiple inheritance.
- Inheritance at multiple levels: Whenever a class inherits the superclass and now this derived class, a ‘parent, child, plus grandchild’ class structure is formed.
- When a superclass gets inherited by numerous derived classes, it is known as hierarchical inheritance.
What Are Local and Global Variables in Python?
Local variable – Any variable declared within a function is referred to as a local variable, as well as its access is limited to that function.
Global variable – Any variable defined outside of a function is referred to be a global variable, and it could be accessed through any function in the program.
Is Indentation Necessary in Python?
Indentation is required in Python and is a component of the language’s syntax. Every programming language has a method for specifying the scope as well as the extension of a code block. It’s called indentation. Indentation improves the readability of the code, which would be presumably why Python requires it.
What’s a Doc-string?
Documentation strings, often known as doc-strings, are used to describe a code block. These can also be used to leave multi-line comments. Such doc-strings are also used to define what a method performs in a class’s methods. By using the help method, we could see the method doc-string.
We hope that this article on python programming Interview Questions gave you a better understanding of the nature of common python interview questions.
Please keep in mind that, in addition to theoretical knowledge, one will need to learn python and have excellent logical as well as analytical skills in order to develop Python programs during the interview.
