This repository contains basic programs in the python programming language.
--> Python is a high-level, general-purpose, and very popular programming language.
--> Python programming language (latest Python 3) is being used in web development, Machine Learning applications, along with all cutting-edge technology in Software Industry.
--> Python is available across widely used platforms like Windows, Linux, and macOS.
--> The biggest strength of Python is huge collection of standard library .
Python programming language can be executed in the following two modes: Python Shell is a command line tool that starts up the python interpreter to read a Python statement, evaluate the result of that statement and then prints the result on the screen.
In Windows search Type IDLE. It is an acronym of "Integrated DeveLopment Environment".
Installing Anaconda Software and using Jupyter Notebook.
Colaboratory, or “Colab” for short, is a product from Google Research which allows anybody to write and execute python code in Jupyter notebook through the browser.
Python programs are written in editors and saved as the file with the .py extension which can be executed further.
✓ Number data type stores numerical values only.--> It is further classified into three different types:
a) Int b) Float c) Complex ✓ A string is a group of characters and can include alphabets, digits or special characters including spaces.
--> We can use single, double, or triple quotes to define a string. ✓ Lists are used when we need a simple iterable collection of data that may go for frequent modifications.
--> For example, if we store the names of students of a class in a list, then it is easy to update the list when some new students join or some leave the course. ✓ Tuples are used when we do not need any change in the data.
--> For example, names of months in a year. ✓ Sets are used when we need uniqueness of elements and to avoid duplicacy it is preferable to use sets.
--> For example, list of items in a museum. ✓ Dictionaries are used if our data is being constantly modified or we need a fast lookup based on a custom key or we need a association between the key : value pair.
--> For Example, A mobile phone book is a good application of dictionary.
Short Description about all libraries used.
To install python library this command is used-pip install library_name
