Like most languages, Python distinguishes between text and binary files. This lesson describes this important distinction.
- [Instructor] Because of the diversity of computers…and operating systems in the world,…some systems handle text files differently than others.…For example, this is a text string…with the word string in it.…The English word string has six letters.…This is followed by a metacharacter…that indicates the end of the line.…This is sometimes referred to as the new line character,…and is generally represented by a backslash…and a lowercase n.…The history of line endings is long and convoluted.…
In many systems it is represented…by a single line feed character, ASCII 10 decimal,…or zero A hex.…These systems include most Unix-based systems,…including modern Macs.…In this case, the string has seven bytes,…including the line feed.…In other systems, a new line is represented…by a carriage return character, ASCII 13 decimal,…or zero D hex.…These systems are mostly obsolete,…including the Apple II and classic Macs,…TRS-80 and old Commodore systems.…
In this case, the string has seven bytes,…including the carriage return.…Microsoft Windows machines use a sequence…
