Here is how I prepare python projects.

Assuming Python3 is already installed

I uses python3 installed by default via OS package. or brew python3 (But if I have a chance to use conda and the others, I may try)

Create python3 virtual environment

I uses venv module

Create venv
bash
```
python3 -m venv venv
```
Activate venv
bash
```
source venv/bin/activate
```
Here you have Isolated environment you can experiment, not affecting entire OS.

Install pip and pip-tools

Upgrade pip to latest version
bash
```
pip install --upgrade pip
```
Install pip-tools for dependencies management
bash
```
pip install pip-tools
```
for more information about pip-tools see https://pypi.org/project/pip-tools/

Installing libraries

Create requirements.in file.
text
```
django>=2.2,<3.0
```
Run pip-compile
text
```
pip-compile
```

You can check cat requirements.txt

text

#
# This file is autogenerated by pip-compile with python 3.10
# To update, run:
#
#    pip-compile
#
django==2.2.28
    # via -r requirements.in
pytz==2022.1
    # via django
sqlparse==0.4.2
    # via django

Install libraries using pip install
bash
```
pip install -r requirements.txt
```

You can check installed libraries by pip list
