Cloud Bootcamp: Python and Git
Learning Python and Git go hand in hand. First, learn Python and then learn git to keep track of any changes made in your code. Python is a great language to learn because it has a great community that you can lean on if you run into issues. Python can be used to write Lambda functions. The cool thing about lambda functions is that they are very short and simple. They work well when you want to do a small task. Git can make big coding projects easier to manage. Git is not hard to learn with a little practice.
Python Web scraping project
Pip install requests
Pip install bs4
Get link to github profile image
This code retrieves the profile image URL of a given GitHub user. Here's a breakdown of what each step does:
Import the necessary libraries:
requests: Allows making HTTP requests to retrieve web pages.
BeautifulSoup from bs4: A library for parsing HTML and XML documents.
Prompt the user to input a GitHub username.
Construct the URL of the user's GitHub profile by concatenating the input username to the base URL: 'https://github.com/' + github_user
Send an HTTP GET request to the constructed URL using requests.get(url) and store the response in the variable r.
Create a BeautifulSoup object named soup by parsing the content of the response using 'html.parser'.
Use soup.find() to locate an HTML img element with the attribute alt set to 'Avatar'. The result is stored in the profile_image variable.
Retrieve the value of the src attribute from the profile_image element using ['src'].
Finally, print the profile image URL.
In summary, this code prompts for a GitHub username, fetches the user's GitHub profile page, parses it using BeautifulSoup, and extracts the URL of the profile image.
Here is the code for the web scraping.
This is me inputting my GitHub profile name.
Here are some Python basics so you can create Python scripts too
Variables- A value that can change, depending on conditions or on information passed to the program.
Receiving Input- Python input() function, as the name suggests, takes input from the user
Type Conversion- The process of converting a data type into another data type
String- a collection of alphabets, words, or other characters.
Arithmetic Operators- a mathematical function that performs a calculation on two operands.
Operator Precedence- Python simply refers to the order of operations. Operators are used to perform operations on variables and values
Comparison Operators- compare the values on either side of them and returns a boolean value
Logical Operators- three Boolean operators, or logical operators: and, or , and not
If Statements- tells the Python interpreter to 'conditionally' execute a particular block of code
While Loops- run a piece of code while a condition is True. It will keep executing the desired set of code statements until that condition is no longer True
Lists- a data structure in Python that is a mutable, or changeable, ordered sequence of elements
For loops- The for loop in Python is an iterating function. If you have a sequence object like a list, you can use the for loop to iterate over the items contained within the list.
The range() Function- creates a collection of numbers on the fly, like 0, 1, 2, 3, 4. This is very useful since the numbers can be used to index into collections such as string. The range() function can be called in a few different ways
Tuples- used to store multiple items in a single variable
Git Basics
Git- a distributed version control system that tracks changes in any set of computer files, usually used for coordinating work among programmers collaboratively developing source code during software development
Github- It provides the distributed version control of Git plus access control, bug tracking, software feature requests, task management, continuous integration, and wikis for every project
Git Repository- the .git/ folder inside a project. This repository tracks all changes made to files in your project, building history over time. Meaning, if you delete the .git/ folder, then you delete your project’s history.
Branch- branches are a part of your everyday development process. Git branches are effectively a pointer to a snapshot of your changes. When you want to add a new feature or fix a bug—no matter how big or how small—you spawn a new branch to encapsulate your changes
Fork- a new repository that shares code and visibility settings with the original “upstream” repository. Forks are often used to iterate on ideas or changes before they are proposed back to the upstream repository, such as in open source projects or when a user does not have write access to the upstream repository
Upstream- upstream refers to the original repo or a branch. For example, when you clone from Github, the remote Github repo is upstream for the cloned local copy
Pull request- let you tell others about changes you've pushed to a branch in a repository on GitHub. Once a pull request is opened, you can discuss and review the potential changes with collaborators and add follow-up commits before your changes are merged into the base branch.
Git stash- git stash temporarily shelves (or stashes) changes you've made to your working copy so you can work on something else, and then come back and re-apply them later on
