To read from file python provide many functions like : Filehandle.read([n]) : reads and return n bytes, if n is not specified it reads entire file. Filehandle.readline([n]) : reads a line of input. If n is specified reads at most n bytes. Read bytes in the form of string ending with line character or blank string if no more bytes are left for ...

\b Matches the empty string, but only at the start or end of a word. \B Matches the empty string, but not at the start or end of a word. \d Matches any decimal digit; equivalent to the set [0-9] in bytes patterns or string patterns with the ASCII flag. In string patterns without the ASCII flag, it will match the whole range of Unicode digits.

Unicode and ASCII • Encoding: How things are actually stored • ASCII "Extensions": how to represent characters for different languages - No universal extension for 256 characters (one byte), so… - ISO-8859-1, ISO-8859-2, CP-1252, etc. • Unicode encoding: - UTF-8: used in Python and elsewhere (uses variable # of 1—4 bytes)

Chapter 12 — String Encoding Introduction Strings are made up of a collection of bytes (8 binary digits) that represent the characters that the string contains. In Python 3 string are encoded following the UTF-8 standard, and may contain 1,112,064 different code points (or symbols). This allows Python programs to process strings of all languages,

an integer between 0 and 255, an equivalent hexadecimal between 0 and FF, or a literal (only ASCII characters are allowed to represent bytes). Bytes can represent anything, such as coded character strings, or pixels of an image. In general, we need to know how they are coded to interpret the correct data type represented by bytes.
