A set of pre-defined "magic functions" of IPython that used with the command-line syntax.

A set of pre-defined "magic functions" of that used with the command-line syntax. There are two types of magic functions line-oriented and cell-oriented. The lines start with a magic % and executed from the command line. They get into an argument the rest of the line, where the arguments are passed without parentheses and quotation marks. Cell magic begins with the double %%, and they are functions that get in an argument not only the rest of the line, but the line below it in a separate argument.
