Manage Necessary Tools

Download & Install Anaconda navigator
Download & Install VS Code → set as PATH
Create an empty folder at desired location → ‘mkdir new_folder’ in powershell.
Open with VS Code → in powershell
```
cd new_folder
code .
```
Create a virtual environment using Conda (iff Anaconda is installed) → conda -p myvenv python==3.1x
- myvenv → is the name of your virtual environment folder.
- python==3.1x → the version of python you want to use for creating your venv. (best python==3.10)
Activate the venv (very important) → conda activate myvenv/
- This means that virtual environment is activated and all the libraries/modules will be installed in this folder only.
Create ‘requirements.txt’ → this file holds all the necessary libraries/modules for development to download (eg. scikit-learn, pandas, numpy, etc.)
Install all the packages written in ‘requirements.txt’ → pip install -r requirements.txt

Types of files

Jupyter Notebook file → ‘filename.ipynb’
Python file → ‘test.py’ (the file name can be anything)
To run the ‘python’ file → python test.py
To run ‘jupyter’ file
1. Install necessary packages
  - ‘ipykernel’ → responsible for providing specific kernel to jupyter notebook file
2. Select the venv python kernel for execution

Programs to try

In python (.py) file
```
print(1+1)
```
In jupyter notebook (ipynb) file
```
