This feature is only available if numbered prompts are in use. )destactiondefaulthelpz-o get_outputz"also print outputs for each input.z-p pypromptsz print classic '>>>' python prompts before each input. This is useful for making documentation, and in conjunction with -o, for producing doctest-ready output. z-traw store_falseTa print the 'translated' history, as IPython understands it. IPython filters your input and converts it all into valid Python source before executing it (things like magics or aliases are turned into function calls, for example). With this option, you'll see the native history instead of the user-entered version: '%%cd /' will be seen as 'get_ipython().run_line_magic("cd", "/")' instead of '%%cd /'. z-ffilenamea FILENAME: instead of printing the output to the screen, redirect it to the given file. The file is always overwritten, though *when it can*, IPython asks for confirmation first. In particular, running the command 'history -f FILENAME' from the IPython Notebook interface will replace FILENAME even if it already exists *without* confirmation. )rrz-y overwritez&yes, overwrite filename even if existsN)rrrrz-gpattern*ac treat the arg as a glob pattern to search for in (full) history. This includes the saved history (almost all commands ever written). The pattern may contain '?' to match one unknown character and '*' to match any number of unknown characters. Use '%%hist -g' to show full saved history (may be very long). )rnargsrrz-llimit?z get the last n lines from all sessions.

By default, input history is printed without line numbers so it can be directly pasted into an editor. Use -n to show them. By default, all input history from the current session is displayed. Ranges of history can be indicated using the syntax: ``4`` Line 4, current session ``4-6`` Lines 4-6, current session ``4-`` Lines 4 onward (to end), current session ``243/1-5`` Lines 1-5, session 243 ``~2/`` All lines of session 2 before current ``~4/4-`` Lines 4 onward (to end), session 4 before current ``~2/7`` Line 7, session 2 before current ``~8/1-~6/5`` From the first line of 8 sessions ago, to the fifth line of 6 sessions ago. Multiple ranges can be entered, separated by spaces The same syntax is used by %macro, %save, %edit, %rerun Examples -------- :: In [6]: %history -n 4-6 4:a = 12 5:print(a**2) 6:%history -n 4-6 cR<V^SP39d \V4#V: RV: 2#)z0Helper function to format line numbers properly./)session_numberstr)sessionlinehistory_managers&&=/usr/lib/python3/dist-packages/IPython/core/magics/history.py_format_lineno-HistoryMagics.history.._format_linenos+1o<<==4y %t, ,FTzFile %r exists.

Use %hist to find out the number. %recall 1-4 Combine the specified lines into one cell, and place it on the next input prompt. See %history for the slice syntax. %recall foo+bar If foo+bar can be evaluated in the user namespace, the result is placed at the next input prompt. Otherwise, the history is searched for lines which contain that substring, and the most recent one is placed at the next input prompt. _Nr3c32"TF q^,xK R#5i)N).0xs& r* 'HistoryMagics.recall..#s0i!isrrecallrepz%Couldn't evaluate or find in history:) r9set_next_inputr&user_nsr)rIrFrLeval ExceptionrGreversedrC)rParg histlinescmdrehs&& r*rhHistoryMagics.recallsEF JJ % %c$***<* : Repeat the last n lines of input, not including the current command. -g foo : Repeat the most recent line which contains foo zl:g:string)modelz"Number of lines must be an integerNz'Requested 0 last lines - nothing to runz+Number of lines to rerun cannot be negativegrrerunz'No lines in history match specificationr3z=== Executing: ===z=== Output: ===F) store_history) parse_optionsint ValueErrorrCr9r)rHlistrGrnrIrFrun_cell) rPrQoptsrRr2rXprwrerps && r*ryHistoryMagics.rerun6s'' V('K  $; S N Av?@QCD::--66q9D D[DI c!A 2299!<=Dd^!A$&3D$  ::-->>tDD::--66q9D"#d!d# ; < IIdO  "# i   DIIdO5AC :; 2$sG G/G,+G,rc)r5)__name__ __module__ __qualname____firstlineno__rrr|rEr rr8rhry__static_attributes____classdictcell__) __classdict__s@r*r r %sm  < e   < e 13 ;|U   5    :    5     7C   8L  gS!J"         3  NJX8<8rs] 8??;;4x CBFCBCBr-
