PYTHON INTERVIEW QUESTIONS

Dear readers, these Python Programming Language Interview Questions have been

designed specially to get you acquainted with the nature of questions you may encounter during

your interview for the subject of Python Programming Language. As per my experience good

interviewers hardly plan to ask any particular question during your interview, normally questions

start with some basic concept of the subject and later they continue based on further discussion

and what you answer 2

What is Python?

Python is a high-level, interpreted, interactive and object-oriented scripting language. Python is

designed to be highly readable. It uses English keywords frequently where as other languages use

punctuation, and it has fewer syntactical constructions than other languages.

Name some of the features of Python.

Following are some of the salient features of python 2

It supports functional and structured programming methods as well as OOP.

It can be used as a scripting language or can be compiled to byte-code for building large

applications.

It supports automatic garbage collection.

It can be easily integrated with C, C++, COM, ActiveX, CORBA, and Java.

What is the purpose of PYTHONPATH environment variable?

PYTHONPATH - It has a role similar to PATH. This variable tells the Python interpreter where to

locate the module files imported into a program. It should include the Python source library

directory and the directories containing Python source code. PYTHONPATH is sometimes preset by

the Python installer.

What is the purpose of PYTHONSTARTUP environment variable?

PYTHONSTARTUP - It contains the path of an initialization file containing Python source code. It is

executed every time you start the interpreter. It is named as .pythonrc.py in Unix and it contains

commands that load utilities or modify PYTHONPATH.

What is the purpose of PYTHONCASEOK environment variable?

PYTHONCASEOK 2 It is used in Windows to instruct Python to find the first case-insensitive match in

an import statement. Set this variable to any value to activate it.

What is the purpose of PYTHONHOME environment variable?

PYTHONHOME 2 It is an alternative module search path. It is usually embedded in the

PYTHONSTARTUP or PYTHONPATH directories to make switching module libraries easy.
