Python environment configuration and basic usage & Pycharm library installation and background settings and avoiding the Venv folder

The default path is the one I marked in red. There is no need to modify the options that are checked by default. We can add environment variables ourselves later.

I installed it in the Python folder under the D drive (a folder I created)

So my path here is very simple, it is: D:\Python

2. Environment variable configuration

Find Advanced System Settings in Settings (right-click this computer, click Properties, or search for "Advanced System Settings" in the search)

Click on Environment Variables and find Path in the system variables

Double-click to open, create new, add your own Python installation path, and confirm to save.

3. Check whether the installation is successful

Win+R to open cmd, enter Python -V to view the Python version

Enter Python and press Enter to open the Python interactive interface (>>>)

At this point we have completed the installation and environment deployment of Python

4. Two modes of Python (editing mode & interactive mode)

By the way, let me tell you that Python has two modes:

One is the interactive mode. Enter a command and press Enter to output the execution result, as shown below:

The other is editing mode, write the complete script (.py file) and run it

To open this editing mode, we need to open IDLE and search for Python to find it.

We can also find the location of this file, create a shortcut and drag it to the desktop

Click the shortcut directly to open it later

In fact, this is still interactive mode. We click file->new file to enter the editing mode.

At this point we can write the script. After writing, click run, and the result will be output in the interactive interface.

2. Pycharm library installation and background settings

Both of these things are done in settings.

1. Python library installation

The library is installed in the Python interpreter (interpreter)

Click the plus sign to search for the library you need

Sometimes there will be problems, you can try the command installation

In the terminal, use pip install + library name

2. Pycharm custom background

This is even simpler. In the appearance, background image, you can select the position of the background image.

You can also adjust the position, transparency, etc. of the image here.

3. How to avoid the Venv folder

The reason why this folder appears in the project is because you use the interpreter of the virtual environment

I don't really like seeing that thing anyway, although it doesn't seem to have any impact.

Solution: Modify to system interpreter

This ends the brief introduction to Python and Pycharm

My name is Myon, and I will update you on the typical use and scripting of Pycharm in the field of web security.

Creation is not easy. If you like it, you can like, follow and support it. Thank you everyone!
