Python for Data Science and Machine Learning

This is the collection of notebooks from a Course on Python for Data Science and Machine Learning by Jose Portilla on Udemy.

Along with the notebooks from the course, I've also added additional Practice notebooks, Exercise links, Cheatsheets that help you hone your skills ✨.

Environment Setup

All the files in this repository require Jupyter installed on your computer to run them. However, you can use the same code and try it out in any of the IDE's available. The notebooks are created using the Latest version of Python 3 through the Anaconda distribution.

Installing Jupyter Using Anaconda

• Install Python and Jupyter using Anaconda Distribution, which includes Python, the Jupyter Notebook, and other commonly used packages for scientific computing and data science.
  

Congratulations, you have installed Jupyter Notebook! To run the notebook, run the following command at the Terminal (Mac/Linux) or Command Prompt (Windows):

jupyter notebook 

Installing Jupyter using pip

As an existing or experienced Python user, you may wish to install Jupyter using Python’s package manager, pip, instead of Anaconda.

• If you have Python 3 installed (which is recommended):

python3 -m pip install --upgrade pip
python3 -m pip install jupyter

• If you have Python 2 installed:

python -m pip install --upgrade pip
python -m pip install jupyter

Congratulations, you have installed Jupyter Notebook! To run the notebook, run the following command at the Terminal (Mac/Linux) or Command Prompt (Windows):

jupyter notebook
