Numbers– They include integers, floating-point numbers, and complex numbers. Q10.What are the common built-in data types in Python?Īns: The common built-in data types in python are. Q9.What are Dict and List comprehensions?Īns: Dictionary and list comprehensions are just another concise way to define dictionaries and lists. For this, we use the symbol before the decorator. Then we write the function it is applied to and simply add the decorator function above the function it has to be applied to. To apply a decorator we first define the decorator function. Decorators generally are defined before the function they are enhancing. Local namespaces– These namespaces are at the local or inner function.Īns: Decorators are used to add some design patterns to a function without changing its structure.Enclosing namespaces– These namespaces are at the higher level or outer function.

  • Global namespace– These are namespaces for all the objects created at the level of the main program.
  • Built-in namespace– These namespaces contain all the built-in objects in python and are available whenever python is running.
  • The namespaces are maintained in python like a dictionary where the key is the namespace and value is the address of the object. As each object is created, its name along with space(the address of the outer function in which the object is), gets created.
  • It provides more functionality with less coding.įind out our Python Training in Top Cities/Countries IndiaĪns: A namespace in python refers to the name which is assigned to each object in python.
  • The data structures used in python are user friendly.
  • Portable– Python programs can run on any platform without requiring any change.
  • It also further provides the facility to import other packages using Python Package Manager(pip).
  • Extensive support for libraries– Python has vast libraries that contain almost any function needed.

  • Free and open-source– Python is free to use and distribute.
  • It automatically gets assigned during execution.
  • Dynamically typed– the developer does not assign data types to variables at the time of coding.
  • #CRACKING THE CODING INTERVIEW LATEST EDITION PDF CODE#

  • Interpreted language– Since python is interpreted language, it executes the code line by line and stops if an error occurs in any line.
  • Easy to use– Python is a high-level programming language that is easy to use, read, write and learn.
  • Q6.What are the benefits of using Python?

    It is a set of rules that specify how to format Python code for maximum readability. Q5.What is pep 8?Īns: PEP stands for Python Enhancement Proposal. Therefore, Python is an interpreted language. Explain.Īns: An interpreted language is any programming language which is not in machine-level code before runtime. To know more about Scripting, you can refer to the Python Scripting Tutorial. What type of language is python? Programming or scripting?Īns: Python is capable of scripting, but in general sense, it is considered as a general-purpose programming language. It’s also often used as “glue” code to get other languages and components to play nice.

  • Python finds use in many spheres – web applications, automation, scientific modeling, big data applications and many more.
  • The numpy package is a good example of this, it’s really quite quick because a lot of the number-crunching it does isn’t actually done by Python Fortunately,Python allows the inclusion of C-based extensions so bottlenecks can be optimized away and often are.
  • Writing Python code is quick but running it is often slower than compiled languages.

    This means that they can be assigned to variables, returned from other functions and passed into functions. In Python, functions are first-class objects.Python does not have access specifiers (like C++’s public, private). Python is well suited to object orientated programming in that it allows the definition of classes along with composition and inheritance.You can do things like x=111 and then x="I'm a string" without error Python is dynamically typed, this means that you don’t need to state the types of variables when you declare them or anything like that.Other interpreted languages include PHP and Ruby. That means that, unlike languages like C and its variants, Python does not need to be compiled before it is run. Tuples are immutable (tuples are lists which can’t be edited). Lists are mutable i.e they can be edited. What is the difference between list and tuples in Python? LIST vs TUPLES LIST Basic Python Interview Questions for Freshers Q1.
