+# <u> Anaconda </u>
+
+# What is Anaconda?
+Anaconda is an open source handy toolkit for dvelopers. It makes job easy for the developers by enabling them to create specific <u>Working Environments</u> and work in them.
+
+
+ ## But What Is Working Environment?
+ Let's understand this with an easy example. Let's say you are designing a house. Every room has its Environment, and according to the nature of that Environment, we add different items to that room. For example, In Kitchen, we will install a sink and gas stove and additional shelves for utensils and vegetables; just like this, we will install different items in our bedroom and living room.
+Now think of this as a developer. A developer is working on various projects simultaneously, and they'll need different packages for different projects. With the help of Anaconda, they can create different **Working Environments** with these different packages that they can access anytime. They'll not have to install these packages every time they switch from one project to another; instead, they switch from one Environment to the other, and they will easily have access to all these packages.
+They can also modify these **Working Environments** by adding, removing, or updating any package anytime.
+
+---
+
+# Installing Anaconda.
+
+* Search **Anaconda Install** in your Web Browser.
+* Click on Anaconda Distribution link that appears.
+* A download option appears on the right part of your screen. Click on download button and wait till it downloads.
+* Click on the exectable file which is downloaded and follow simple steps that will follow on screen. Just make sure about the following:
+  + While installing select Install for **Just Me** option.
+  + Select **<u>Add Anaconda to my PATH environment variable</u>**.
++ Now wait till it installs and then we can work with Anaconda Prompt.
+---
+# Working in an Environment in Anaconda 
+## Creating an Environment
+Open the Anaconda command prompt. You'll be direct to a base environment in Anaconda.  
+To setup a new Environment, type **"<u>conda create -- name NAME python version</u>"** (without inverted commas)  
+Here, NAME is the name of the environment you want to create and Python version will specify which version of pyhton you want to work with in this environment.  
+*for example:* ***<u>conda create --name basisoflearning python=3.9</u>*** will create an environment named 'basisoflearning' which will work with python 3.9  
+### <u>To enter the environment</u>, 
+type ***<u>conda activate basisoflearning</u>*** and you'll enter basisoflearning environment.
+### <u>To install any package in the Environment</u>,  
+we will have to give different commands to download different packages in Anaconda which are easily available on the web.  
+*for example :*  to install NumPy we can give command ***<u>conda instll -c anaconda numpy</u>***. this will install numpy i the environment.
+
+### <u>To exit the environment</u>,
+type ***<u>conda deactivate</u>*** and you'll head out of that environment.
+
+---   
+
+## Other Important Commands Examples.
+
+
+* ***<u>conda list</u>*** command fetches us list of all the packages installed in the environment.
+* ***<u>conda update numpy</u>*** will update numpy library to its latest version.
+* ***<u>conda env list</u>*** gives list of all the environments created on the system.
