After installation, open the command line and enter the following command to verify that Python has been installed successfully: ```python python --version ``` If the version number of Python is displayed, then Python has been successfully installed. This is the content related to system requirements and installing Python. Next, we will continue with the steps for installing Jupyter Notebook. # 3. Installing Jupyter Notebook In this chapter, we will introduce how to install Jupyter Notebook. Jupyter Notebook is a powerful interactive tool that allows users to create and share documents in a browser, including live code, mathematical equations, and visual charts. ### 3.1 Installation Using pip One of the simplest methods to install Jupyter Notebook is by using the Python package manager pip. Here are the steps to install Jupyter Notebook: 1. Open the command line or terminal. 2. Run the following command to install Jupyter Notebook: ```bash pip install jupyter ``` 3. After the installation is complete, you can verify the successful installation of Jupyter Notebook by running: ```bash jupyter notebook --version ``` ### 3.2 Installation Using Anaconda Another common method is to use Anaconda to install Jupyter Notebook, which is an open-source distribution for data science and machine learning. Here are the steps to install Jupyter Notebook using Anaconda: 1. First, ensure that you have Anaconda installed. If not, visit the [Anaconda official website](*** *** *** "Create" to create a new environment. 4. After creating the new environment, select it and click "Open Terminal" to open the terminal. 5. Run the following command to install Jupyter Notebook: ```bash conda install jupyter ``` By following these steps, you can easily install Jupyter Notebook in your environment. Next, we will continue with the configuration of Jupyter Notebook. # 4. Configuring Jupyter Notebook ### 4.1 Setting a Password In this section, we will introduce how to set up password protection in the Jupyter Notebook configuration. #### Steps: 1. Open the command line and run the following command to generate a configuration file: ```bash jupyter notebook --generate-config ``` 2. Then generate a password hash value with the following command: ```bash python -c "from notebook.auth import passwd; print(passwd())" ``` 3. Copy the generated password hash value, find `c.NotebookApp.password` in the configuration file, and set it to the generated password hash value. 4. Finally, restart Jupyter Notebook to apply the changes. ### 4.2 Configuring File Paths In this section, we will learn how to set the configuration file path for Jupyter Notebook. #### Detailed Steps: 1. First, determine the default Jupyter Notebook configuration file path, which is typically `~/.jupyter/jupyter_notebook_config.py`. 2. If you need to modify the configuration file path, you can achieve this by specifying the `JUPYTER_CONFIG_DIR` environment variable. 3. For example, if you want to save the configuration file in a custom path `/path/to/config/`, you can run the following command: ```bash export JUPYTER_CONFIG_DIR=/path/to/config/ ``` 4. After setting the environment variable, starting Jupyter Notebook will look for the configuration file at the specified path. #### Configuration File Path Table: The following table lists the default paths and custom paths for Jupyter Notebook configuration files: | Default Path | Custom Path | |----------------------------------------|------------------------------------| | `~/.jupyter/jupyter_notebook_config.py` | `/path/to/config/jupyter_notebook_config.py` | ### Mermaid Flowchart Display: ```mermaid graph TD A[Generate Configuration File] --> B[Set Password] B --> C[Generate Password Hash Value] C --> D[Set Password Hash in Configuration File] D --> E[Restart Jupyter Notebook] ``` ```mermaid graph LR A[Determine Default Configuration File Path] --> B[Set Custom Path] B --> C[Specify JUPYTER_CONFIG_DIR Environment Variable] C --> D[Start Jupyter Notebook] D --> E[Search for Configuration File at the Specified Path] ``` # 5. Starting Jupyter Notebook After starting Jupyter Notebook, you can begin using this interactive development tool in your browser. This section will detail how to start Jupyter Notebook via the command line and access its interface. #### 5.1 Starting via Command Line Run the following command in the command line to start Jupyter Notebook: ```bash jupyter notebook ``` After executing this command, the system will print a series of information and open the Jupyter Notebook interface in the default browser. #### 5.2 Accessing the Jupyter Notebook Interface In the browser, you will see the main interface of Jupyter Notebook. This interface is similar to a file browser, allowing you to browse folders, create new Notebooks, and open existing Notebooks, among other operations. You can perform various actions through the navigation bar and buttons on the interface, such as creating, saving, and exporting Notebooks. Here is a simple Mermaid flowchart showing the process of starting Jupyter Notebook: ```mermaid graph LR A[Start Jupyter Notebook] --> B[Did it Start Successfully?] B -->|Yes| C[Open Browser] B -->|No| D[Check Log Information] ``` Once Jupyter Notebook is successfully started and the interface is opened, you can begin creating new Notebooks, writing code, and conducting data analysis and visualization. Next, in the following chapter, we will introduce how to use Jupyter Notebook. # 6. Using Jupyter Notebook ### 6.1 Creating a New Notebook In Jupyter Notebook, we can create a new Notebook to write and run code. #### Steps to Create a Notebook: 1. Click the "New" button in the upper left corner of the Jupyter interface. 2. Choose the desired programming language, such as Python3, to create a new Notebook. 3. Name the Notebook descriptively for easy management and retrieval later. ### 6.2 Writing and Executing Code Once we have created a new Notebook, we can start writing and executing code. #### Steps to Write Code: 1. Enter Python code in the Notebook's code cell, for example: ```python # Calculate and print the sum of numbers from 1 to 10 sum = 0 for i in range(1, 11): sum += i print(sum) ``` 2. Press Shift+Enter or click the run button in the toolbar to execute the code. 3. Jupyter will immediately run the code and display the result, such as outputting 55, which is the sum of numbers from 1 to 10. #### Displaying Code Execution Results in a Table: The following table shows the result of executing the above code: | Sequence | Result | |----------|--------| | 1 | 55 | #### Illustrating Code Execution Process with a Flowchart: ```mermaid graph LR A(Start) --> B(Initialize sum to 0) B --> C{Is the condition for i satisfied?} C -->|Yes| D{Calculate the sum of sum and i, and update sum} D --> E{Increase the value of i} E --> C C -->|No| F(Output the value of sum) F --> G(End) ``` By following these steps, we can easily write and execute code in Jupyter Notebook, achieving various tasks such as data analysis and machine learning. # 7.
