IPython

IPython is an enhanced interactive Python interpreter that provides a powerful command-line interface with advanced features like syntax highlighting, tab completion, magic commands, and rich display capabilities. It serves as the computational kernel for Jupyter notebooks.

Core Features

Enhanced Interactive Shell

• Syntax Highlighting: Real-time code coloring for better readability
• Tab Completion: Intelligent autocompletion for objects, methods, and file paths
• History Management: Persistent command history with search capabilities
• Rich Output: Native display of images, plots, and formatted data structures
• Object Introspection: Detailed information about objects using ? and ??

Magic Commands

IPython provides magic commands prefixed with % for single-line operations or %% for cell-wide operations:

%timeit sum(range(100))           # Time execution
%debug                            # Enter debugger
%matplotlib inline                # Enable inline plotting
%%writefile script.py             # Write cell contents to file

Integration Capabilities

• Jupyter Kernel: Powers Jupyter notebooks and JupyterLab
• Shell Integration: Execute system commands with !
• Editor Integration: Works with vim, emacs, and modern IDEs
• Debugger: Built-in IPython debugger with enhanced features
