Creating Virtual Environments - Python |
https://dev.to/vincod/creating-virtual-environments-python-4dn4
|
Creating Virtual Environments PythonA virtual environment in Python is a way to create isolated environments for different projects so that each project can have its own specific version of Python and installed packages This allows for more flexibility and control over dependencies and helps to prevent conflicts between different projects One popular tool for creating virtual environments in Python is virtualenv It allows you to create a new environment and activate it and then you can install packages using pip in the environment Once you are done working on the project you can deactivate the environment and switch to another one Another popular tool is conda It is a package and environment management system that is commonly used in scientific computing and data science It allows you to create virtual environments and install packages similar to virtualenv but also has additional features such as managing multiple versions of packages and handling dependencies To create a virtual environment with virtualenv code pip install virtualenv virtualenv myenv source myenv bin activateTo create a virtual environment with conda Copy code conda create name myenv conda activate myenvOnce you have activated the environment you can install packages using pip or conda and they will be installed into that environment and not globally |

Statistics for data science with practice Day of Days Data Science Bootcamp from noob to expert GitHub link Complete Data Science Bootcamp Main Post Complete Data Science Bootcamp Recap Day Yesterday we have studied in detail about statistics Python Let s startIn today s data driven world understanding and working with data is an essential skill for businesses researchers and professionals of all backgrounds One of the most powerful tools for data analysis is the Python programming language With its powerful libraries such as NumPy and pandas Python provides a wide range of statistical and data analysis capabilities In this article we will explore some of the most important concepts in statistics such as mean median mode variance and standard deviation and learn how to use Python to calculate these values We will also look at more advanced topics such as percentiles quartiles and z scores and learn how to fill missing values and create new columns in a dataset Whether you are a beginner or an experienced data analyst this article will provide you with the knowledge and tools you need to work with data in Python Mean The mean is the average value of a set of data It is calculated by adding all the values in a set of data and then dividing by the number of values in the set For example if we have a set of data the mean would be Importing librariesimport numpy as np Creating a sample data setdata Meanmean np mean data print Mean mean Mean Median The median is the middle value of a set of data when it is arranged in numerical order If the set has an odd number of values the median is the middle value If the set has an even number of values the median is the average of the two middle values For example if we have a set of data the median would be Medianmedian np median data print Median median Median Mode The mode is the value that appears most frequently in a set of data A set of data can have multiple modes or no mode at all For example if we have a set of data the mode would be Modeimport statistics as stmode st mode data print Mode mode Mode Range The range is the difference between the highest and lowest values in a set of data For example if we have a set of data the range would be Rangerange np ptp data print Range range Range Variance The variance is a measure of how much the values in a set of data deviate from the mean It is calculated by taking the sum of the squares of the differences between each value and the mean and then dividing by the number of values in the set Variancevariance np var data print Variance variance Variance Standard deviation The standard deviation is a measure of how spread out the values in a set of data are It is calculated by taking the square root of the variance Standard deviationstd dev np std data print Standard deviation std dev Standard deviation Percentiles and quartiles Percentiles and quartiles are measures of the distribution of a set of data A percentile is a value that separates a set of data into equal parts A quartile is a value that separates a set of data into equal parts Percentilespercentile np percentile data print th percentile percentile print th percentile Median percentile print th percentile percentile th percentile th percentile Median th percentile Z scores A z score is a measure of how far away a value is from the mean in terms of standard deviations It is calculated by taking the difference between a value and the mean and then dividing by the standard deviation Z scoresz scores data mean std devprint Z scores z scores Z scores Summary The key concepts of statistics such as mean median mode variance standard deviation percentiles quartiles and z scores are explained in detail along with examples of how to calculate these values using Python libraries such as NumPy and pandas Additionally the article also covers more advanced topics such as filling missing values and creating new columns in a dataset The article is suitable for both beginners and experienced data analysts providing them with the knowledge and tools they need to work with data in Python The article provides sample data in CSV format which can be used to practice the concepts explained Exercise Question you will find in the exercise notebook of Day on GitHub If you liked it then |

Lambda Serverless Computing Platform Lambda Serverless Computing PlatformIn recent years cloud computing has become an increasingly popular way to store and manage data Amazon Web Services AWS is one of the leading cloud providers offering a wide range of services and features to help businesses get the most out of their cloud infrastructure One of the most powerful tools available on AWS is its Lambda service which allows developers to create and run code without having to manage any underlying infrastructure Lambda is a serverless computing platform that allows developers to write code without having to worry about managing servers or other infrastructure This makes it ideal for applications that require rapid scaling or have unpredictable workloads With Lambda developers can focus on writing code rather than worrying about managing servers or dealing with other operational tasks Lambda functions are written in Node js Python Java C Go and Ruby Once written these functions can be deployed directly from the AWS console or using the AWS CLI tool Once deployed Lambda functions are triggered by events such as changes in an Amazon S bucket or an incoming request from an API gateway When triggered the function runs in a secure environment provided by AWS and returns a response back to the caller The main advantage of using Lambda is that it allows developers to quickly build applications without having to worry about managing servers or other infrastructure components This makes it ideal for applications that require rapid scaling or have unpredictable workloads such as webhooks and real time data processing tasks Additionally Lambda functions are highly cost effective since they only run when triggered and don t require any upfront costs for server provisioning or maintenance Overall AWS Lambda is a powerful tool for developers looking to quickly build applications without having to worry about managing servers or other infrastructure components It provides a secure environment for running code with minimal overhead costs and can be used for a variety of tasks ranging from webhooks to real time data processing tasks |
