Softtek Most Frequently Asked Python Latest Interview Questions Answers
How will you remove last object from a list?
list.pop(obj=list[-1]) − Removes and returns last object or obj from list.
How will you remove an object from a list?
list.remove(obj) − Removes object obj from list.
How will you reverse a list?
list.reverse() − Reverses objects of list in place.
How will you sort a list?
list.sort([func]) − Sorts objects of list, use compare func if given.
Q97).Name five modules that are included in python by default (many people come searching for this, so I included some more examples of modules which are often used)
datetime (used to manipulate date and time)
re (regular expressions)
urllib, urllib2 (handles many HTTP things)
string (a collection of different groups of strings for example all lower_case letters etc)
itertools (permutations, combinations and other useful iterables)
ctypes (from python docs: create and manipulate C data types in Python)
email (from python docs: A package for parsing, handling, and generating email messages)
__future__ (Record of incompatible language changes. like division operator is different and much better when imported from __future__)
sqlite3 (handles database of SQLite type)
unittest (from python docs: Python unit testing framework, based on Erich Gamma’s JUnit and Kent Beck’s Smalltalk testing framework)
xml (xml support)
logging (defines logger classes. enables python to log details on severity level basis)
os (operating system support)
pickle (similar to json. can put any data structure to external files)
subprocess (from docs: This module allows you to spawn processes, connect to their input/output/error pipes, and obtain their return codes)
webbrowser (from docs: Interfaces for launching and remotely controlling Web browsers.)
traceback (Extract, format and print Python stack traces)
Name a module that is not included in python by default
mechanize
django
gtk
A lot of other can be found at pypi.
What is __init__.py used for?
It declares that the given directory is a package. #Python Docs (From Endophage‘s comment).
Is There A Tool To Help Find Bugs Or Perform Static Analysis?
Yes.
PyChecker is a static analysis tool that finds bugs in Python source code and warns about code complexity and style.
Pylint is another tool that checks if a module satisfies a coding standard, and also makes it possible to write plug-ins to add a custom feature.
What Programming Paradigm does Python supports?
Python supports both Procedural Programming approach as well as Object Oriented Programming Approach. Moreover, you can use both the approaches in a single Python program.
How to take input from the User in Python?
Python provides a built-in method to accept input from the user.
It is as follows: input(“Enter the Input”)
However, in order to store the input in a variable, you must write a variable name before the input() method.
It can done as follows: var1=input(“Enter the input”)
How to terminate a line of code in Python?
Python is an extremely efficient and easy to use language. You can terminate a Python line of code using a Semi-Colon. However, it is not mandatory to use a Semi-colon at the end of every line. It is up to you if you want to use it or not.
Enlist Popular Frameworks of Python?
Major Frameworks: Django and Pyramid
Minor Frameworks: Bottle and Flask
What is Lambda in Python specification?
It is a single expression which is an Anonymous Method often used as Inline function.
Enlist the Applications of Python Programming?
1. Web Application Development and Web Frameworks such as DJango and Pyramid.
2. Game Development
3. Desktop Based Applications
4. Micro Frameworks such as Bottle and Flask
