Jupyter Notebook Edit Mode and Command Mode

In Jupyter Notebook, there are two main modes that you can switch between: Edit Mode and Command Mode.

The "ln" command is used to switch between "Full", "Edit", and "Mode" - "Mode" is the default and least restrictive mode, "Edit" allows the user to edit non-executable cells, and "Full" prevents all editing by default. You can also use the "Flip Full/Edit/Mode" shortcut (F3) to quickly toggle between these modes.

In a Jupyter Notebook, edit mode refers to the state where cells can be edited, and changes can be made to previously typed code or text.

Itis state where you can modify the content of a cell, such as adding or editing code or text. When a cell is in edit mode, the cell's border will be green, and a cursor will appear, allowing you to type and make changes.

Example:

  1. Entering Edit Mode

    • Double-click on a cell, or press Enter while the cell is selected.
    • The border of the cell will turn green, indicating that it is in edit mode.

  2. Editing a Cell

    • Suppose you have the following code in a cell
  • While in edit mode, you can click inside the cell and change the text to:

Steps to Demonstrate Edit Mode

  1. Select a Cell:

    • Click on a cell to select it. The border will be blue, indicating that it is in command mode.

  2. Enter Edit Mode:

    • Press Enter. The border will turn green.

  3. Make Changes:

    • Modify the code or text inside the cell as needed.

  4. Exit Edit Mode:

    • Press Esc to exit edit mode and return to command mode. The border will turn blue again.

Command Mode:
In a Jupyter Notebook, "command mode" is the state where you can perform notebook-level operations such as adding, deleting, and moving cells, but not directly editing the content within the cells. When a cell is in command mode, its border is blue, and keyboard shortcuts are available for various notebook actions.

Example

  1. Entering Command Mode

    • Press Esc while in edit mode, or simply click on a cell if you are not already in edit mode.
    • The border of the cell will turn blue, indicating that it is in command mode.

  2. Using Command Mode Shortcuts

    • While in command mode, you can use various keyboard shortcuts to perform actions on cells.

Common Shortcuts in Command Mode

  • Enter Edit Mode: Press Enter
  • Insert Cell Above: Press A
  • Insert Cell Below: Press B
  • Cut Cell: Press X
  • Copy Cell: Press C
  • Paste Cell: Press V
  • Delete Cell: Press D twice (D, D)
  • Change Cell to Markdown: Press M
  • Change Cell to Code: Press Y
  • Save Notebook: Press S
  • Run Cell: Press Shift + Enter

Steps to Demonstrate Command Mode

  1. Select a Cell:

    • Click on a cell to select it. The border will be blue, indicating command mode.

  2. Perform Actions:

    • Use keyboard shortcuts to perform actions. For example, press B to add a new cell below the selected cell.

  3. Return to Edit Mode:

    • Press Enter to return to edit mode if you need to modify the content of a cell.

Loops in Python - For Loop, While Loop and Nested Loops

Understanding Loops in Python: A Beginner's Guide: Loops are a fundamental concept in programming, allowing you to repeat a block of code multiple times without writing it out repeatedly. This guide will introduce you to loops in Python, focusing on two main types: for loops and while loops. We'll also explore some practical examples to solidify your understanding. What Are Loops? In programming, loops are used to automate repetitive tasks. Instead of writing the same code multiple times, you can use a loop to execute it repeatedly until a certain condition is met. 1. For Loops: A for  loop in Python iterates over a sequence (such as a list, tuple, string, or range) and executes a block of code for each item in the sequence. Here's the basic syntax: Example 1: Iterating Over a List Output: Example 2: Using the Range Function The range() function generates a sequence of numbers, which is particularly useful in loops. Example 3. Nested For Loops: You can use a loop inside...
