Useful tips for GitHub

In the main page of GitHub, typing 's': search.
When entering a certain project, the nested files are inconvenient to search. Typing 't'，search for all files in this repository.
Typing 'command+k': Navigation inside the page
Click into a file, say XX.py. Typing 'L': navigate to a certain line of the file, and you may copy that line.
Typing 'b': you can find the correction, updates, and all history record of the opened file.
Navigate to a specific project, and type the dot symbol '.', it would open a web-based VScode editor and you can run any program on that web.
Web-based editor. On the top of the Github website, type:
```
 gitpod.io/#/
```

infront of the address. With this tool, you don’t need to download the project locally and build the corresponding environment with terminal. The project will be opened in a web-based editor, it’s sort of a server and you may use it as your personal laptop. Many popular languages are pre-installed including Python, Java, Go. You can execute some project by typing commands, and check the result in the website.

How to clone repository from Github

First create a local directory where you want to store this library

In my Macbook, I created a directory: GIT_local in Documents, so firstly, cd to the path(Drag this directory into terminal and get the address):

cd /Users/stephen/Documents/GIT_local

Then, create a directory for the specific project:

mkdir newproject

Copy the URL of the specific project:

cd to the newproject and type the command:

git clone the_copied_URL

When you open the directory again, you'll find that you already have the repository. Then navigate to the repository's address.

Gitpod

Gitpod is a cloud-based Integrated Development Environment (IDE) that allows developers to write, build, test, and debug their code from any device with a web browser. It provides a complete and ready-to-code development environment, simplifying the setup and maintenance of development environments for projects.

Gitpod integrates with popular code hosting platforms such as GitHub, GitLab, and Bitbucket. When you open a repository on one of these platforms in Gitpod, it automatically creates a new development environment tailored to the project's specific needs. This can include pre-installed tools, languages, and frameworks, as well as pre-built dependencies.

Gitpod offers features like:

-Prebuilt workspaces: Gitpod can automatically build your project's dependencies whenever new code is pushed to a repository, ensuring that workspaces start up quickly.

-Collaborative coding: Gitpod supports real-time collaboration, allowing multiple developers to work on the same codebase and share their workspaces with others.

-Customizable environments: You can create custom Docker images for your projects to ensure that all the necessary tools, packages, and settings are available when starting a new workspace.

-Integration with popular tools: Gitpod integrates with VS Code, allowing you to use familiar extensions and shortcuts while working in the cloud-based IDE.

To get started with Gitpod, you can visit their website (https://www.gitpod.io/) and sign up for a free or paid plan, depending on your needs.

Pip

When using Python, you might need to install and use certain packages. And there is a command available for that known as 'pip', it's the standard Python package manager that downloads and installs packages from the Python package index. With pip, you can install, upgrade, and uninstall various Python packages. You'll learn how to use it, and how to handle pip errors.

What is the error pip: command not found?

Sometimes when you are installing packages, you might face the error: pip: command not found. This error could be due to the following reasons:

-Pip is not installed.

-Pip is installed, but it is not compatible with the current environment.

(P.S On Linux, you must install the pip package manager separately as it is an independent package. But on Mac, you do not need to install pip manually, as long as you are working with Python 3.x. version)

Troubleshooting the error pip: command not found

First, check if pip is installed.

python3 -m pip --version

If pip is not installed, you can follow the install steps here for your respective OS: https://pip.pypa.io/en/stable/installation/

Second, upgrade pip to the latest version.

python -m pip install --upgrade pip

Third, fix environment issues.

It is possible that you are trying to use the wrong version of pip. For example, pip3 works for Python3, whereas pip works only for Python2.

You can check your Python version on Linux and Mac like this:

python --version

If any package is missing during the running of Jupyter notebook, you can directly open a new terminal to install the corresponding package:

pip install XXX

Check if any packages have been installed on your computer system. For example, 'numpy'

import numpy as np
print("Numpy version:", np.__version__)

PyPI(Python Package Index)

Find, install and publish Python packages with the Python Package Index
