# # IPython Notebook Basics

# ## Project directory

# * IPython Notebooks are just files (`.ipynb`) on your file system
# * The Notebook server is aware of Notebooks in a single directory, which we call the **Notebook directory**
# * If you cd to a Notebook directory and type:
# 
#         jupyter notebook
# 
#   you will see the Notebooks in that directory in the dashboard

# ## Notebook files

# Notebook files:
# 
# * Are just that - files (`.ipynb`) on your file system
# * Contain JSON data

# In[7]:


import nbformat

with open('Notebook Basics.ipynb') as f:
    nb = nbformat.v4.reads_json(f.read())    


# In[9]:


nb.cells[0:5]


# * Embed code, Markdown text, LaTeX equations, images
# * Are version control friendly: post your Notebooks on GitHub
# * Can be viewed online by anyone at http://nbviewer.org

# IPython Notebooks can also be exported to `.py` files (see "File:Download As" menu item). You can tell the Notebook server to always save these `.py` files alongside the `.ipynb` files by starting the Notebook as:
# 
#     ipython notebook --script
# 
# You can import Notebooks from the main Dashboard or simply by copying a Notebook into the Notebook directory.
