3.1.1 Installing Jupyter notebooks. Mac’s come shipped with a version of Python, but it is most likely outdated, and it doesn’t contain everything we want. In order to get running, I strongly recommend downloading the Anaconda distribution over other distributions,. Import sys sys.executable in my Python 3 console, the output is. Usrbinpython3 and I'm able to import whatever libraries I've installed with pip3, no problem. When I do so in my Jupyter Notebook running a Python 3 kernel, the output is. Usrbinpython and the libraries that I've. How to load a dataset from a ZIP file to Jupyter Notebook or Visual Studio for data analysis using python and pandas. To load data from a zip file in jupyter notebook or visual studio code, you have to do something a little extra. There are 2 options to load a zip file in jupyter notebook.

Code fragments in a Jupyter notebook file are structured as executable cells. Each cell is marked with the #%% comment and can be executed independently by clicking the icon in the gutter. To execute all cells at once, click on the Jupyter toolbar.

Run code cells

• For the target cell press Ctrl+Enter. Alternatively, you can click the icon and select Run Cell. PyCharm launches the Jupyter server, executes the code cell, and renders the output in the Preview pane.

  When executing one cell at a time, mind code dependencies. For example, the second cell in the code fragment uses the variables defined in the first cell. So, if you modify the N value, the changes will be reflected in the scatter chart only after the first cell gets executed. You can use smart shortcuts to execute the current cell and select the below one: Shift+Enter.

• To execute all code cells in your notebook, click on the notebook toolbar or press Ctrl + Shift + Alt + Enter. To run all code cells above the current cell and handle possible code dependencies, click on the notebook toolbar and select the Run All Above command from the quick list.

When you stop the server and change the server or kernel, you have to execute all cells with dependencies again, because execution results are valid for the current server session only.

View variables

• This functionality is available only for local Jupyter server kernels.

  When you execute a cell, the Variables tab of the Jupyter server tool window opens automatically.

  By default, variables are loaded asynchronously. To change the loading policy, click in the Variables tab, select Variables Loading Policy, and select one of the available modes. See Managing Variables Loading Policy for more details.

  You can click the link to the right of the variable to preview its values in the tabular form:

  Note that Variables tab will appear each time you execute a cell, so if, by some reasons, you need to close it permanently, deselect the corresponding option in the project settings (Settings/Preferences | Build, Execution, Deployment | Jupyter).

  In addition to previewing values of the variables in the Variables tab, you can watch the values of the variable usages in the editor. Note that variable assignments are not shown.

  This option is enabled by default. To disable it, deselect the Show Inline Values in the Editor checkbox in the project settings (Settings/Preferences | Build, Execution, Deployment | Jupyter).

When you work with a substantial number of code cells, you can effectively navigate between the Editor and Preview panes by using auto scrolling.

Jump to the target output fragment or target code cell

1. Enable auto scrolling from the source by clicking the icon, then select a code cell in the Editor pane. You will be positioned on the target output fragment in the Preview pane.

2. Enable auto scrolling to the source code by clicking the icon on the Jupyter toolbar, then select an arbitrary output fragment in the Preview pane. You'll be positioned on the source code cell in the Editor pane.

PyCharm provides the full-functional Jupyter Notebook Debugger.

This functionality is available only for local Jupyter server kernels.

Debug code in Jupyter notebook

1. Set the breakpoints in the selected cell and press Alt + Shift + Enter for Windows or ⌥⇧↩ for macOS. Alternatively, you can click the icon, and select Debug Cell.

   The Jupyter Notebook Debugger tool window opens.

2. Use the stepping toolbar buttonsstepping toolbar to choose on which line you want to stop next and switch to the Debugger tab to preview the variable values:

   Debugging is performed within a single code cell. However, if your code cell calls a function from any cell that has been already debugged, you can step into it. The related breakpoints will also work. Note that the cell with the function must be debugged not just executed.

   The debugger may skip a cell if you change its source code or execute it not under the debugger. Also, you can see a warning message when trying to modify the cell code during the debugging session.

   Similarly, you can step into a function called from a Python file that is located in the same project.

3. Proceed with the debugging steps to complete the execution of the cell.

Clear the notebook output

• To erase the execution output in the Preview area, click on the Jupyter notebook toolbar and select the Clear Outputs command from the quick list. Evaluate the results in the Preview area.

With PyCharm you can always quickly preview reference documentation for a particular variable, type, or argument.

Preview reference documentation

1. To view reference information for any element of a particular code cell, place the caret within the target code cell and type ? <type/variable/argument>. (in this example, you will preview documentation for plt.scatter). Note that a code element should be accessible within the code cell.

2. Execute the cell. The Introspection tab opens in the Jupyter tool window.

3. Preview reference documentation in the Introspection tab.

Note that the Introspection tab shows documentation for the latest requested code element. Even though you proceed with executing other code cells, restart the server, or delete the line with your request, this information will be shown.

Step 1 – Download and Install Anaconda

Go to: https://www.anaconda.com/download/

Click on the download button for the python 3 installer for your browser.

Once the installer has downloaded, double-click on the installer and follow directions to install anaconda on your machine. (You can leave the default install location as is).

You can leave all the settings as default. If by default it says that you cannot install on that disk, select your main disk to install on.

Step 2 – Open Jupyter Notebook

Method 1: Open from the command line –

Open Command Prompt (Windows) or Terminal (Mac). This application will be already on your computer. To find it, simply search your computer (e.g. for Windows press the Windows button then type Command and the Command Prompt application should be found).

In the box that pops up, type the following line:

jupyter notebook [and then press enter]

Jupyter notebook should open in your default web browser.

Method 2: Open from Anaconda Navigator:

Find Anaconda Navigator on your system (e.g. in Mac, type Anaconda into the search bar and press enter).

Click Launch under Jupyter Notebook.

Step 3 – Navigate to where you want to create your notebook

In the browser window that pops up, navigate to the folder where you want to create your notebook.

If you don’t know where to start (and if you left the install defaults as they were), just click on Documents. This will place you in your Documents folder and all your work will be saved there.

Step 4 Create a new notebook

Once you are in the folder you want to create the new notebook, look to the top right. Click the button below the logout button which says New. A menu will drop down and click on Python 3.

Step 5 – Begin coding

Try typing the following in the first box:

print(“Hello World”)

After you’ve typed that click Cell in the menu bar and then click the Run Cells option (or press shift-enter).

If you would like to start working with some of the libraries you have, try importing them. For example type:

import pandas [and then press shift-enter]

It should run and you have successfully import the pandas library and are ready to begin working with pandas. Anaconda has automatically installed a number of libraries (including pandas, numpy, and sklearn) for you to start using.

Step 6 – Save your notebook.

Click on the title of the notebook (Currently it has the title “Untitled“)

Then, within Jupyter menu bar click File and then Save and Checkpoint (or press control-s for Windows or command-s for mac)

The notebook will be saved to the folder you navigated to when you created your notebook. (E.g. if you navigated to Documents, the notebook will be in your documents folder). Note – to reopen the notebook, you need to open Jupyter Notebooks and navigate to your folder again in Jupyter Notebook’s file browser (you can’t simply click on the notebook in your system’s file browser like you would be able to do with another file type like a word document).

Note about Jupyter’s cell types:

Jupyter notebooks can, amongst other things, process text as well as code. If you can run the code, check the kind of cell that you have. If the code simply appears as text, you have a “markdown” cell. Click on the

If you can’t run the code, check the kind of cell that you have. If the code simply appears as text, you have a “markdown” cell. Click on the drop-down menu and change the cell to “code”. You should see “In” and two square brackets to the left of the cell. It will look like this:

In [ ]:

Note about installing other libraries:

Anaconda comes with a lot of libraries, but if you want more, you open Terminal (for Mac) or Command Prompt (for Windows) and type in the following:

conda install package_name

For example, to install seaborn you would type

conda install seaborn [and then press enter]

Installers often ask for yes/no confirmation, in which case you type:
