What is the difference between List and Tuple in Python?
A list can hold ordered sets of all data types in Python (including another list). A list's elements can be modified after creation. The implication of iterations is time-consuming in the list. Operations like insertion and deletion are better performed and consumes more memory. They are mutable
The tuple type is very similar to the list type but the elements cannot be modified after creation (similar to strings). Implications of iterations are much faster in tuples.Elements can be accessed better and consumes less memory.They are immutable.
What type of language is Python?
Python is a dynamically typed interpreted language. These types of languages are typically referred to as “scripting” languages because code is not compiled to a binary form. By dynamically typed I mean that types do not need to be declared when coding, the interpreter figures them out at runtime. Python is neither a true compiled time nor pure interpreted language.
What is PYTHON PATH?
PYTHON PATH is an environment variable which you can set to add additional directories where python will look for modules and packages. For most installations, you should not set these variables since they are not needed for Python to run. Python knows where to find its standard library.
What are Python Modules?
A module is a file containing Python definitions and statements. A module is a file with the suffix
.py
appended. Within a module, the module’s name (as a string) is available as the value of the global variable__name__
. To break down large programmes into tiny, manageable and structured files, we use modules. Additionally, modules have code reusability.Instead of copying their meanings into various programmes, we can define our most used functions in a module and import them.What are local variables and global variables in Python?
A variable that is declared outside the function or inside the global scope is referred to as a global variable. This implies that it is possible to access a global variable within or outside the function.
A variable declared within the body of the function or within the local scope is referred to as a local variable.

Machine learning is one of the most exciting techniques one has ever encountered.The field of study that gives computers the ability to learn without being explicitly programmed is machine learning.Their are platforms that can help you improve your Machine Learning skills. Today I've come up with the list of some of my favorite platforms. Platforms to Improve Machine Learning Skills 1. Kaggle The online community of data scientists and machine learning practitioners is Kaggle, a subsidiary of Google LLC. Kaggle is the largest data science community in the world.Kaggle enables users in a web-based data-science environment to find and publish data sets, explore and build models, work with other data scientists and machine learning engineers, and enter competitions to solve challenges in data science.With it's free GPUs, high paying competitions,massive community , thousands on datasets and notebooks, this platform helps a lot. 2. Seedbank It was launched by 'TensorFlow...
