Everything is a cell!¶

And here are some empty cells:

In [ ]:

Multi mode:

In [18]:

2 + 2

Out[18]:

Cell Types¶

This is a markdown cell. It can contain different formatting options as bold, or italic text, code blocks:

def my_function(x, y):
    pass

Or even images:

In [19]:

# this is a code cell
2 + 2

Out[19]:

Now try it yourself:

In [20]:

Turn this cell into a markdown cell

  Cell In[20], line 1
    Turn this cell into a markdown cell
         ^
SyntaxError: invalid syntax

Turn this cell into a code cell

Working with code¶

Execute the following cells in order:

In [21]:

import numpy as np
import matplotlib.pyplot as plt
%matplotlib inline

In [4]:

x = np.linspace(0, 10, 500)
y = np.cumsum(np.random.randn(500, 6), 0)

In [5]:

plt.figure(figsize=(12, 7))
plt.plot(x, y)
plt.legend('ABCDEF', ncol=2, loc='upper left')

Out[5]:

<matplotlib.legend.Legend at 0x73e3a88b6510>

Out[29]:

'Abdulrahman'

2) Complete the function `add` to produce the right result¶

In [27]:

def add(x, y):
    return x + y

In [28]:

result = add(3, 5)
print(result)  # Output: 8

Exercises¶

This is a quick demonstration of how exercises work on Notebooks.ai.

green-divider

Example 1: Solve the add function¶

Complete the code of the function add, that receives 2 numbers and should return the sum of them:

In [ ]:

def add(x, y):
    pass

You can use the + operator to sum numbers.

In [ ]:

def add(x, y):
    return x + y

Welcome to our Jupyter Tutorial. This is an interactive tutorial focused on getting you familiarized with Notebooks and interactive labs.

Part 1: everything is a cell¶

Jupyter Notebooks are organized as a set of "cells". Each cell can contain different types of content: like Python code (or R, Julia, etc), images or even human readable text (markdown), like the one you're currently reading.

I've left a couple of empty cells below for you to see them:

In [ ]:

This is another cell containing Markdown (human readable) code. And below, another empty cell:

In [ ]:

You can edit these cells just by double clicking on them. Try editing the following cell:

👉 Double click on me 👈

When you double click the cell, it should open an "edit mode", and you should see something similar to:

If you're seeing those asterisks, it's because you've correctly entered "Edit Mode". Once you've made the changes, you have to "execute", or "run" the cell to reflect the changes. To do that just click on the little play button on the top menu bar:

Jupyter notebooks are optimized for an efficient workflow. There are many keyboard shortcuts that will let you interact with your documents, run code and make other changes; mastering these shortcuts will speed up your work. For example, there are two shortcuts to execute a cell:

shift + return: Run cell and advance to the next one.
ctrl + return: Run the cell but don't change focus.

Try them with the following cell:

In [ ]:

2 + 2

You can try executing these cells as many times as you want, it won't break anything

`ctrl + Return` effect:¶

As you can see in the following animation, the code is correctly executed (it returns 4) and the focus (the blue line at the left side of the cell) stays in the same cell.

ctrl+enter effect

Now compare it to the next shortcut, shift + return:

`shift + Return` effect:¶

shift+enter effect

As you can see, every time I execute code the focus changes to the cell below.

Part 2: Working with code¶

Jupyter notebooks have amazing features to include text and images and create beautiful, human readable documents as you've just seen. But their main benefit is working with code. Now we're going to import a few libraries and start experimenting with Python code. We've already done the simple 2 + 2 before, so let's do something a little bit more interesting. First, we need to import numpy and matplotlib:

In [1]:

import numpy as np
import matplotlib.pyplot as plt
%matplotlib inline

Notebooks.ai include all the most popular Data Science and Deep Learning libraries already installed. And even if there's one missing, you can always install it in your own environment (more on that later). We've just imported these two libraries:

numpy the most popular Python library for array manipulation and numeric computing
matplotlib the most popular visualization library in the Python ecosystem.

Let's now execute a few lines of code and generate some plots:

In [2]:

x = np.linspace(0, 10, 500)
y = np.cumsum(np.random.randn(500, 6), 0)

In [3]:

plt.figure(figsize=(12, 7))
plt.plot(x, y)
plt.legend('ABCDEF', ncol=2, loc='upper left')

Out[3]:

<matplotlib.legend.Legend at 0x12187e690>

But what is that 😱? Just random generated datapoints, but you can clearly see how simple is to do numeric processing and plotting with Notebooks.ai.

green-divider

Part 3: Interacting with data¶

Jupyter and Python make it really simple to intereact with files in your local storage. These files are securely stored in the cloud and you can access them from anywhere in the world.

As an example, we're going to load two CSV files (that you can preview in this public spreadsheet) into our notebook and play with them.

The CSVs contain price of Bitcoin and Ether for the first two weeks of December 2023, with a granularity of one minute. This is what's usually referred to as OHLC (Open, High, Low, Close).
