What is Python good for? Answer: Python is a high-level general-purpose programming language that can be applied to many different classes of problems. Name some of the features of Python? Answer: Following are some of the salient features of python 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 provides very high-level dynamic data types and supports dynamic type checking. It supports automatic garbage collection. What Is Python? Answer: Python is one of the most successful interpreted languages. Few other interpreted languages are PHP and Javascript. What are the Runtime Errors? Answer: The errors which occur after starting the execution of the programs are known as runtime errors.

Runtime errors can occur because of. Mention what the Django templates consist of? Answer: The template is a simple text file. Explain the use of session in Django framework? Answer: Django provides a session that lets you store and retrieve data on a per-site-visitor basis. Django abstracts the process of sending and receiving cookies, by placing a session ID cookie on the client-side and storing all the related data on the server-side.

Is Python object-oriented? Python is Object Oriented Programming language. OOP is the programming paradigm based on classes and instances of those classes called objects. Name few Python modules for Statistical, Numerical and scientific computations? Explain how to overload constructors or methods in Python? Explain how to redirect the output of a python script from standout ie. Answer: They are two possible ways of redirecting the output from standout to a file.

Explain the shortest way to open a text file and display its contents? How do you create a dictionary which can preserve the order of pairs? Python 2. When does a dictionary is used instead of a list? How are Inheritance and Overriding methods are related? For Instance, If class B and class A both contain a method called func , then func in class B can override func in class A. Similarly, a method of class A can call another method defined in A that can invoke a method of B that overrides it.

What is a Python module? Inside the module, you can refer to the module name as a string that is stored in the global variable name. Name the File-related modules in Python? Using them you can create files, update their contents, copy, and delete files. The libraries are os, os. Here, os and os. Answer: DML Commands are used to modify the data of the database objects.

How to display the contents of the text file in reverse order? Answer: convert the given file into a list. Which statement of Python is used whenever a statement is required syntactically but the program needs no action? In such a scenario, use a try-except block with pass statement in the except block. Explain the use of with statement?

Explain all the file processing modes supported by Python? Answer: Python allows you to open files in one of the three modes. They are:. What is Encapsulation? Answer: The concept of binding or grouping related data members along with its related functionalities is known as an Encapsulation. What is Garbage Collection? Answer: The concept of removing unused or unreferenced objects from the memory location is known as a Garbage Collection. While executing the program, if garbage collection takes place then more memory space is available for the program and rest of the program execution becomes faster.

It is impossible to deallocate those portions of memory that are reserved by the C library. What is JSON? It is a popular data format for storing data in NoSQL databases. Generally , JSON is built on 2 structures.

What are negative indexes and why are they used? Answer: The sequences in Python are indexed and it consists of the positive as well as negative numbers. The negative index is used to remove any new-line spaces from the string and allow the string to except the last character that is given as S[]. The negative index is also used to show the index to represent the string in the correct order.

Explain the use of decorators? Answer: Decorators in Python are used to modify or inject code in functions or classes. Using decorators, you can wrap a class or function method call so that a piece of code can be executed before or after the execution of the original code.

Decorators can be used to check for permissions, modify or track the arguments passed to a method, logging the calls to a specific method, etc. What is the difference between NumPy and SciPy? Answer: In an ideal world, NumPy would contain nothing but the array data type and the most basic operations: indexing, sorting, reshaping, basic elementwise functions, et cetera.

Does Python support interfaces like in Java? Answer: Discuss. Python does not provide interfaces like in Java. Abstract Base Class is a mechanism for specifying what methods must be implemented by its implementation subclasses. This module was made available from Python 2. What is Multithreading? Answer: Thread Is a functionality or logic which can execute simultaneously along with the other part of the program Thread is a lightweight process Any program which is under execution is known as process We can define the threads in python by overwriting run method of the Thread class Thread class is a predefined class which is defined in the threading module Thread in the module is a predefined module If we call the run method directly the logic of the run method will be executed as a normal method logic In order to execute the logic of the run method as we use the start method of thread class.

Import threading Class x threading. Thread : Def run self : For p in range 1, : print p Class y threading. How would you define a protected member in a Python class?

Answer: All the members of a class in Python are public by default. Name a few methods that are used to implement Functionally Oriented Programming in Python?

Answer: Python supports methods called iterators in Python3 , such as filter , map , and reduce , that are very useful when you need to iterate over the items in a list, create a dictionary, or extract a subset of a list.

How is Python executed? Answer: Python files are compiled to bytecode. Alternate Answer: Type python. What is the difference between. Answer: python files are Python source files. How do you invoke the Python interpreter for interactive use? Answer: python or python. What is the process of compilation and linking in python?

Answer: The compiling and linking allows the new extensions to be compiled properly without any error and the linking can be done only when it passes the compiled procedure. If the dynamic loading is used then it depends on the style that is being provided with the system. The python interpreter can be used to provide the dynamic loading of the configuration setup files and will rebuild the interpreter.

What are tuples in Python? Answer: A tuple is another sequence data type that is similar to the list. A tuple consists of a number of values separated by commas. Unlike lists, however, tuples are enclosed within parentheses. What happens if an error occurs that is not handled in the except block?

Answer: The program terminates. How are Phon blocks defined? Answer: By indents or tabs. This is different from most other languages which use symbols to define blocks.

Python Interview Questions And Answers Pdf

How would you modify the definition of extendList to produce the presumably desired behavior? Many will mistakenly expect list1 to be equal to [10] and list3 to be equal to ['a'] , thinking that the list argument will be set to its default value of [] each time extendList is called. However, what actually happens is that the new default list is created only once when the function is defined , and that same list is then used subsequently whenever extendList is invoked without a list argument being specified. The definition of the extendList function could be modified as follows , though, to always begin a new list when no list argument is specified, which is more likely to have been the desired behavior:. How would you modify the definition of multipliers to produce the presumably desired behavior?
