Using the help() system Mac OS and GNU/Linux secrets Windows secrets Using the help mode Background briefing -- math and numbers The usual culprits The ivory tower of numbers Integer numbers Rational numbers. Floating-point numbersDecimal numbers Complex numbers Outside the numbers Assigning values to variables Writing scripts and seeing output Gathering user input Handling exceptions Looping and trying again Handling text and strings Converting between numbers and strings Parsing strings Organizing our software Working with files and folders Creating a file Reading a file Defining more complex logical conditions Solving problems -- recovering a lost password Reading a word corpus Reading a ZIP archive Using brute-force search Summary Chapter 2: Acquiring Intelligence Data. Accessing data from the InternetBackground briefing -- the TCP/IP protocols Using http.client for HTTP GET Changing our client information Using FTP in Python Downloading a file via FTP Using our FTP get() function Using urllib for HTTP, FTP, or file access Using urllib for FTP access Using a REST API in Python Getting simple REST data Using more complex RESTful queries Saving our data via JSON Organizing collections of data Using a Python list Using list index operations Using a Python tuple Using generator expressions with list-of-tuples Using a Python dictionary mapping. Using the dictionary access methodsTransforming sequences with generator functions Using the defaultdict and counter mappings Using a Python set Using the for statement with a collection Using Python operators on collections Solving problems -- currency conversion rates Summary Chapter 3: Encoding Secret Messages with Steganography Background briefing -- handling file formats Working with the OS filesystem glob os Processing simple text files Working with ZIP files Working with JSON files Working with CSV files JPEG and PNG graphics -- pixels and metadata. Using the Pillow libraryAdding the required supporting libraries GNU/Linux secrets Mac OS X secrets Windows secrets Installing and confirming Pillow Decoding and encoding image data Manipulating images -- resizing and thumbnails Manipulating images -- cropping Manipulating images -- enhancing Manipulating images -- filtering Manipulating images -- ImageOps Some approaches to steganography Getting the red-channel data Extracting bytes from Unicode characters Manipulating bits and bytes Assembling the bits Encoding the message Decoding a message Detecting and preventing tampering.
