Function no_var_expand

IPython/core/magic.py:271–284

Mark a magic function as not needing variable expansion By default, IPython interprets `{a}` or `$a` in the line passed to magics as variables that should be interpolated from the interactive namespace before passing the line to the magic function. This is not always desirable, e.g.

(magic_func)

    """Mark a magic function as not needing variable expansion

    By default, IPython interprets `{a}` or `$a` in the line passed to magics

    This is not always desirable, e.g. when the magic executes Python code
    (%timeit, %time, etc.).
    Decorate magics with `@no_var_expand` to opt-out of variable expansion.
