Question { 716 }

What are some of your favourite designs in apps and websites?

Answer

I think the user interface of Airbnb is a really good example of design. A smooth user experience is promoted by the layout's simplicity and ease of use, which enable quick reservations and simple navigation. The Spotify app is another noteworthy example; user engagement is increased by its simple layout, tailored suggestions, and seamless transitions.

Additionally, I like Medium's website design because it emphasizes content readability with a simple yet powerful layout. My approach to developing engaging and user-friendly interfaces has been influenced by these designs, which place a high value on user-centricity, usability, and aesthetic appeal.

Question { 689 }

What is the difference between micro-interactions and animations?

Answer

Micro-interactions, such as pressing a button or filling out a form, are brief, targeted interactions that take place within a larger interface. They are short in duration and provide quick, direct consumer feedback.

Animations, on the other hand, include more extensive motions or changes brought about by user input or incorporated into the interface as a whole. Animations, which are usually intended to amuse users, foster engagement by adding a feeling of movement and interactivity to the interface design.

Question { 1165 }

What are the types of literals in Python?

Answer

A string literal is created by appending text to a variable that is enclosed in single or double quotes. To create multiline literals, assign the multiline text enclosed in triple quotes.
Numerical Literal: They could include complex numbers, integers, or floating-point data.
Character Literal: One character is enclosed in double quotations to create this.

True or False is the Boolean literal.
List collections, tuple literals, set literals, dictionary literals, and set literals are the four categories of literals.

What are Python modules? Name a few Python built-in modules that are often used.

Answer

Files containing Python code are called modules. This code can make use of variables, classes, or functions. A.py file containing executable code is called a Python module. The frequently utilized built-in modules are as follows:

Question { 1169 }

Differentiate between range and xrange.

Answer

Functionality-wise, xrange and range are nearly identical. Both of these let you create an integer list that you may use however you like. The only distinction between xrange and range is that x range returns an xrange object, whereas range returns a Python list object. Range will use as much memory as possible to produce your array of numbers, which can result in a memory error and crash your program. This is particularly true if you are working with a device that needs a lot of memory, like a phone. It has a memory issue and is a beast.

Question { 952 }

In Python, how do you remark numerous lines?

Answer

Multi-line comments are those that contain more than one line. All lines that will be commented must begin with a #. To mark many lines, you can also utilize a handy shortcut. All you need to do is input a # once while holding down the Ctrl key and left-clicking wherever you want a # character to appear. Every line where you place your cursor will have a comment added to it.

Question { 1133 }

Why isn't all the memory de-allocated when Python exits?

Answer

Certain Python modules are not always released or deallocated when Python terminates, particularly those that include circular references to other objects or objects referenced from global namespaces.
Python's effective cleanup mechanism would attempt to de-allocate/destroy all other objects upon termination.
De-allocating the RAM that the C library has reserved is difficult.

Question { 1160 }

Explain Python packages.

Answer

A Python package is an assembly of modules arranged in a directory, usually for the purpose of managing and organizing related features. To tell Python that a directory should be handled as a package, each package includes a __init__.py file. Packages logically aggregate similar code components, such functions, classes, or variables, into distinct modules, improving code structure and reusability.

Question { 1152 }

What are the benefits of NumPy arrays over (nested) Python lists?

Answer

Python lists are suitable general-purpose containers. Python's list comprehensions make them easy to develop and use, and they enable (relatively) fast insertion, deletion, appending, and concatenation.

They have several drawbacks, such as the inability to perform "vectorized" operations like elementwise addition and multiplication and the requirement for Python to store type information for each element while working on it due to the possibility of include objects of multiple kinds.

Histograms, algebra, linear, basic statistics, rapid searching, convolutions, FFTs, and more are among the characteristics that make NumPy arrays faster.

Question { 1128 }

What are the different types of inheritance in Python?

Answer

Single inheritance: A derived class acquires the members of a single superclass.

many inheritance: A derived class inherits traits from many base classes.

Muti-level inheritance: base1 is the source of the derived class D1, whereas base2 is the source of D2.

Any child class can be inherited from a single base class using hierarchical inheritance.
