Parameters ---------- prompt_re : regular expression A regular expression matching any input prompt (including continuation) initial_re : regular expression, optional A regular expression matching only the initial prompt, but not continuation. If no initial expression is given, prompt_re will be used everywhere. Used mainly for plain Python prompts, where the continuation prompt ``...`` is a valid Python expression in Python 3, so shouldn't be stripped. Notes ----- If `initial_re` and `prompt_re differ`, only `initial_re` will be tested against the first line. If any prompt is found on the first two lines, prompts will be stripped from the rest of the block.
