What is PIP?

Pip is a package manager for Python projects. Thanks to it we will be able to install many libraries, programs, and tools simply as if it were a system package.

But the most interesting utility of PIP is that by creating a Python virtual environment, we can use it to install programs in the path of the project without affecting other projects or the system itself.

The operation is similar to that of a package manager like APT, DNF, or Zypper because we can install, uninstall and update Python packages from the PIP repositories.

So, let’s install it and get it ready for you to use without any problems.

Install Pip on Fedora 34

The installation will be done using the terminal. So, open a new session from the main menu. When you have opened the terminal, you can update the distribution by running

sudo dnf update

Then, you can perform a search in the Fedora repositories.

sudo dnf search pip

And you will get a wide range of output per screen, but the best results are in the following one:

In this case, the package is python3-pip which we will have to install using DNF

sudo dnf install python3-pip

This will start the installation which should not take too long.

In the end, you can check the installed version

pip3 --version

Sample Output

pip 21.0.1 from /usr/lib/python3.9/site-packages/pip (python 3.9)

Although PIP is ready to use, you should always work with the latest version available. So, using it we can upgrade to the latest version.

So, to update PIP, run the following command:

sudo -H pip3 install -U pip
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.
Requirement already satisfied: pip in /usr/lib/python3.9/site-packages (21.0.1)
Collecting pip
  Downloading pip-21.1.2-py3-none-any.whl (1.5 MB)
     |████████████████████████████████| 1.5 MB 7.4 MB/s 
Installing collected packages: pip
Successfully installed pip-21.1.2

This way, we will have the latest version of PIP.

pip3 --version
pip 21.1.2 from /usr/local/lib/python3.9/site-packages/pip (python 3.9)

Now yes, PIP is ready for battle.

Conclusion

PIP is a useful and basic tool in daily work with Python. So installing it should be a must for almost any programmer and sysadmin. As you may have noticed, the process is quite simple and anyone can complete it without any problem.

• It has development servers and debugging features
• Use Jinja2 template styles
• Allows the creation of secure cookies for sites

Prerequisite

As mentioned, this is an application written in Python. Consequently, it is essential to have this language installed. To know how to do it, see our tutorial.

How to download and install Flask in Windows 10. Step by step.

In the first place, it is necessary to create a folder where you will save the configuration of the app. With this in mind, we will create it inside Documents and call it my_flask.

Then open a CMD as an administrator from the folder location and run the following command:

py -m venv env

With this command we have created the virtual environment of Flask. In effect, all you have to do is go to the folder and look at the content.

Back to the terminal, please run the following command to activate the environment:

env\Scripts\activate

Now, install Flask with the following command:

pip install flask

Once Flask is downloaded and installed, the wizard recommends updating the pip. With this in mind, run the following command:

python.exe -m pip install --upgrade pip

Creating the configuration file.

Now it’s time to create an app.py file. Consequently, some advanced text editor like Notepad++ is recommended. Finally, save it in the newly created folder.

Then, please establish the application with the following order:

set FLASK_APP=app.py

Then open the app.py file and add the following lines:

from flask import Flask
app = Flask(name)
@app.route('/')
def index():
return '<h1>Hello</h1>'

To run this environment go to the terminal and there run:

flask run

Then, select the assigned IP address in the terminal. Then open it in any browser.

Ultimately we have seen how you install Flask on Windows 10. Besides, it is written in python so it has a great support. See you later!

The post How to install FLASK in Windows 10 appeared first on Linux Windows and android Tutorials.

However, Windows 10 by default is not compatible with this programming language, so to run applications programmed with it, we have to install all the libraries and dependencies of Python in the system and configure them, a task that for many people can become complicated.

Installing Python 3

For this reason, today we will learn how to install Python 3 in Windows 10. In the first place, we need to download it, Once on the page, we choose Download Python 3.7.4 (or the number that is when we visit it, as long as it is 3)

Once the download is finished, we have to proceed to execute it as the Administrator user. A window will appear, select both options at the bottom of it; install launcher for all users (to grant access for all users) and Add Python 3.7 PATH (add the path of the interpreter to the PATH variable). This second option is imperative to select, inasmuch as allow run python.exe from anywhere on the command line (otherwise, we would have to always put the absolute path).

Then, press Next to start the installation.

A couple of minutes later, our installation will be finished. If a warning message appears, asking for a disabling path length limit, then we need to approve it.

Testing Python 3 operation

To start python, we have to press Windows + R keys, to invocate CMD box. Once there, type python. Thereupon we will have a console with Python interpreter and we could make operations like additions, subtraction and more.

To go out of Python, type

exit()

Postscript. Installing Python 3 from Windows Store

It is quite known that most of the users in Windows 10 would like to install programs, just by clicking on some buttons. As a matter of fact, Windows Store is full of programs (free or paid) ready to be downloaded and installed by users. With this in mind, Python Software Foundation has to dabble in Windows Store, offer Python 3 to those users who own at least Windows 10 version 17763.0 or high. However, it does not come with absolutely all the components that are included in the complete conventional installer. Inasmuch as, developers are still working to be able to bring all these components to this installer. In addition, they also warn that there may be a problem and some applications may not work properly. Although this may be true, this option is very interesting and for sure will be improved in the future.

Now, we have installed Python 3 in Windows 10, and we can start to use it. Please visit our tutorial about the backup windows registry.

What is TermRecord?

TermRecord is an application written in Python that records our terminal session. One that finishes the recording exports it into a self-contained HTML output that is easy to share.

On the other hand, TermRecord can be installed on many Linux and MacOS distributions. It is open source released under the MIT license and this provides us with the security of auditing the source code. In addition, the application has some controls that allow you to better enjoy the recorded content.

The application is especially useful if we need to share our terminal session. Let’s think that in a technology department you need to contrast some information that is generated in the terminal. Moreover, it is ideal for learning tutorials in the field of education or training.

So, let us install it.

Record your terminal session with TermRecord

The application depends on Python, so if you use Linux it is very difficult not to install it. So we can install PIP to help us with the installation.

If you use Debian, Ubuntu, Linux Mint or derivatives, just write the following on a terminal:

:~$ sudo apt install python-pip

However, if you use CentOS or RHLE, you can install it with this command:

:~$ sudo yum install python-pip

In case you use OpenSUSE, run this command:

:~$ sudo zypper in python-pip

Next, install TermRecord using PIP.

:~$ sudo pip install TermRecord

And to start to record your terminal session, use the following command:

:~$ TermRecord -o session.html

When you want to finish recording, type exit and press enter.

Next, open the file using your browser.

TermRecord is a wonder because it detects the size of our terminal window. In addition to this, it has interactive buttons in playback such as pause, play and ability to speed up and slow down playback.

So, enjoy it.

Conclusion

Linux is a very flexible system. In this post, we talk about TermRecord and how it is possible to record the terminal session easily, quickly and without using heavy applications.
