Git is a distributed version control system DVCS designed for efficient source code management, suitable for both small and large projects. It allows multiple developers to work on a project simultaneously without overwriting changes, supporting collaborative work, continuous integration, and deployment. This Git and GitHub tutorial is designed for beginners to learn fundamentals and advanced concepts, including branching, pushing, merging conflicts, and essential Git commands. Prerequisites include familiarity with the command line interface CLI, a text editor, and basic programming concepts. Git was developed by Linus Torvalds for Linux kernel development and tracks changes, manages versions, and enables collaboration among developers. It provides a complete backup of project history in a repository. GitHub is a hosting service for Git repositories, facilitating project access, collaboration, and version control. The tutorial covers topics such as Git installation, repository creation, Git Bash usage, managing branches, resolving conflicts, and working with platforms like Bitbucket and GitHub. The text is a comprehensive guide to using Git and GitHub, covering a wide range of topics. It includes instructions on working directories, using submodules, writing good commit messages, deleting local repositories, and understanding Git workflows like Git Flow versus GitHub Flow. There are sections on packfiles, garbage collection, and the differences between concepts like HEAD, working tree, and index. Installation instructions for Git across various platforms Ubuntu, macOS, Windows, Raspberry Pi, Termux, etc. are provided, along with credential setup. The guide explains essential Git commands, their usage, and advanced topics like debugging, merging, rebasing, patch operations, hooks, subtree, filtering commit history, and handling merge conflicts. It also covers managing branches, syncing forks, searching errors, and differences between various Git operations e.g., push origin vs. push origin master, merging vs. rebasing. The text provides a comprehensive guide on using Git and GitHub. It covers creating repositories, adding code of conduct, forking and cloning projects, and adding various media files to a repository. The text explains how to push projects, handle authentication issues, solve common Git problems, and manage repositories. It discusses using different IDEs like VSCode, Android Studio, and PyCharm, for Git operations, including creating branches and pull requests. Additionally, it details deploying applications to platforms like Heroku and Firebase, publishing static websites on GitHub Pages, and collaborating on GitHub. Other topics include the use of Git with R and Eclipse, configuring OAuth apps, generating personal access tokens, and setting up GitLab repositories.

s=smtplib.SMTP("smtp.gmail.com", 587)
Recommended: Please strive your approach on first, before moving on to the solution.
# Python code to illustrate Sending mail from
# your Gmail account
import smtplib
# creates SMTP session
s = smtplib.SMTP('smtp.gmail.com', 587)
# start TLS for security
s.starttls()
# Authentication
s.login("sender_email_id", "sender_email_id_password")
# message to be sent
message = "Message_you_need_to_send"
# sending the mail
s.sendmail("sender_email_id", "receiver_email_id", message)
# terminating the session
s.quit()
Sending same message to multiple people
Also Read : How to get a list of parameter names inside Python function?For example, you have a list of email ids to which you need to send the same mail. To do so, insert a “for” loop between the initialization and termination of the SMTP session. Loop will initialize turn by turn and after sending the email, SMTP session will be terminated.
# Python code to illustrate Sending mail
# to multiple users
# from your Gmail account
import smtplib
# list of email_id to send the mail
li = ["[email protected]", "[email protected]"]
for dest in li:
s = smtplib.SMTP('smtp.gmail.com', 587)
s.starttls()
s.login("sender_email_id", "sender_email_id_password")
message = "Message_you_need_to_send"
s.sendmail("sender_email_id", dest, message)
s.quit()
- This code can send simple mail which doesn’t have any attachment or any subject.
- One of the most amazing things about this code is that we can send any number of emails using this and Gmail mostly put your mail in the primary section. Sent mails would not be detected as Spam generally.
- File handling can also be used to fetch email id from a file and further used for sending the emails.
