Question and Answer

Python was created by Guido van Rossum, and released in 1991.

It is a general-purpose computer programming language. It is a high-level, object-oriented language which can run equally on different platforms such as Windows, Linux, UNIX, and Macintosh. Its high-level built-in data structures, combined with dynamic typing and dynamic binding. It is widely used in data science, machine learning and artificial intelligence domain.

It is easy to learn and require less code to develop the applications.

It is widely used for:

  • Web development (server-side).
  • Software development.
  • Mathematics.
  • System scripting.
  • Python is an interpreted, object-oriented, high-level programming language with dynamic semantics.
  • Python is compatible with different platforms like Windows, Mac, Linux, Raspberry Pi, etc.
  • Python has a simple syntax as compared to other languages.
  • Python allows a developer to write programs with fewer lines than some other programming languages.
  • Python runs on an interpreter system, means that the code can be executed as soon as it is written. It helps to provide a prototype very quickly.
  • Python can be described as a procedural way, an object-orientated way or a functional way.
  • The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed.

Python is used in various software domains some application areas are given below.

  • Web and Internet Development
  • Games
  • Scientific and computational applications
  • Language development
  • Image processing and graphic design applications
  • Enterprise and business applications development
  • Operating systems
  • GUI based desktop applications

Advantages of Python are:

  • Python is Interpreted language

Interpreted: Python is an interpreted language. It does not require prior compilation of code and executes instructions directly.

  • It is Free and open source

Free and open source: It is an open-source project which is publicly available to reuse. It can be downloaded free of cost.

  • It is Extensible

Extensible: It is very flexible and extensible with any module.

  • Object-oriented

Object-oriented: Python allows to implement the Object-Oriented concepts to build application solution.

  • It has Built-in data structure

Built-in data structure: Tuple, List, and Dictionary are useful integrated data structures provided by the language.

  • Readability
  • High-Level Language
  • Cross-platform

Portable: Python programs can run on cross platforms without affecting its performance.

PEP 8 stands for Python Enhancement Proposal, it can be defined as a document that helps us to provide the guidelines on how to write the Python code. It is basically a set of rules that specify how to format Python code for maximum readability. It was written by Guido van Rossum, Barry Warsaw and Nick Coghlan in 2001.

A function is a section of the program or a block of code that is written once and can be executed whenever required in the program. A function is a block of self-contained statements which has a valid name, parameters list, and body. Functions make programming more functional and modular to perform modular tasks. Python provides several built-in functions to complete tasks and also allows a user to create new functions as well.

There are three types of functions:

  • Built-In Functions: copy(), len(), count() are the some built-in functions.
  • User-defined Functions: Functions which are defined by a user known as user-defined functions.
  • Anonymous functions: These functions are also known as lambda functions because they are not declared with the standard def keyword.

Example: A general syntax of user defined function is given below.

There are two parameters passing mechanism in Python:

  • Pass by references
  • Pass by value

By default, all the parameters (arguments) are passed "by reference" to the functions. Thus, if you change the value of the parameter within a function, the change is reflected in the calling function as well. It indicates the original variable. For example, if a variable is declared as a = 10, and passed to a function where it's value is modified to a = 20. Both the variables denote to the same value.

Python Interview Questions

The pass by value is that whenever we pass the arguments to the function only values pass to the function, no reference passes to the function. It makes it immutable that means not changeable. Both variables hold the different values, and original value persists even after modifying in the function.

Python Interview Questions

Python has a default argument concept which helps to call a method using an arbitrary number of arguments.

Python's constructor: _init__ () is the first method of a class. Whenever we try to instantiate an object __init__() is automatically invoked by python to initialize members of an object. We can't overload constructors or methods in Python. It shows an error if we try to overload.

It is a string's function which converts all uppercase characters into lowercase and vice versa. It is used to alter the existing case of the string. This method creates a copy of the string which contains all the characters in the swap case. If the string is in lowercase, it generates a small case string and vice versa. It automatically ignores all the non-alphabetic characters. See an example below.

To remove leading characters from a string, we can use lstrip() function. It is Python string function which takes an optional char type parameter. If a parameter is provided, it removes the character. Otherwise, it removes all the leading spaces from the string.
