Jupyter Notebook

 Introduction to Jupyter Notebook

A Jupyter Notebook is an open source web application that allows data scientists to create and share documents that include live code, equations, and other multimedia resources.

Use of Jupyter Notebook:

Jupyter notebooks are used for all sorts of data science tasks such as exploratory data analysis (EDA), data cleaning and transformation, data visualization, statistical modeling, machine learning, and deep learning.

Advantage of Using Jupyter Notebook:

• Useful for "showing the work" through a combination of code, markdown, links, and images.
• Jupyter notebooks can also be converted to a number of standard output formats (HTML, PowerPoint, LaTex, PDF, Restructured Text, Markdown, Python)

Working of Jupyter Notebook

Step 1) Open Jupyter Notebook from apps.

step 2) In your default browser a web page will open like this and default directory will be C drive of your system.

 

Step 3) If you want to run and save your code in other directory then follow these steps:

1. Open Anaconda Prompt (anaconda 3) from start menu.
2. Type the directory name followed by colon (:) and then press Enter (Example - d:)
3. Type Jupyter notebook and then Enter.

Step 4) Open your preferred folder and then click on New -> Python 3.

Step 5) A new notebook will be opened with name 'Untitled.ipynb' and you can run your code here.
