Python Interview Questions

Python is one of the most widely used languages, which is why certification is also important in the programming field. Visit the Bestinterviewquestion.com website for the most frequently asked Python Interview Questions. They help you increase your preparation for basic concepts so you get the most benefit and also help you learn more about Python.

What is Python? What are the benefits of using Python?

Python is a programming language with objects, modules, threads, exceptions, and automatic recall command. The advantages of pythons are that it is simple and easy, portable, extensible, integrated data structure, and is open source.

What are the main features of Python?

Python is an interpreted language, unlike other languages ​​like C and variants, Python does not need compilations before they are executed. There are other interpreted languages ​​like PHP and Ruby.

Python is written dynamically, which means that it is not necessary to specify types of variables when they are declared or something similar. You can do things like x = 111 and then x = "I'm a string" without errors.

Python adapts very well to object-oriented programming because it allows you to define classes along with composition and inheritance. It does not have input specifications (e.g. public, private C ++).

In Python, features are first-class objects. This means that they can be assigned to variables, returned from other functions, and transferred to functions. Classes are also first-class objects.

Writing Python code is fast, but execution can be slower than compiled languages. Fortunately, Python allows C-based extensions to be included so that bottlenecks can be optimized and often are. The NumPy package is a good example of this, is really fast because most of the calculation it does is not performed by Python.

Python is useful in many areas: automation, web applications, big data applications, scientific modeling, and many more. It is also often used as an "intermediate" code to make other languages ​​and components play well.

The python language is an interpreted language. The Python program is run directly from the source code. Converts the source code that is written by the programmer into an intermediate language, which is again translated into the machine language that must be executed.

Python memory is managed by private space in Python stacks. All Python objects and data structures are in a private heap. The developer does not have access to this private heap and the interpreter takes care of this Python private heap.

The allocation of Python stack space for Python objects is done by the Python memory manager. The main API gives access to some tools for the programmer to code.

Python also has a built-in garbage collector, which recycles all unused memory and frees up memory and makes it available to battery space.

In Python, each name entered has a place where it lives and where it can be hooked. This is known as a namespace. It is like a box where a variable name is assigned to the placed object. Every time the variable is searched, this box will be searched to obtain the corresponding object.
