IPython cheat sheet

This is a cheat sheet for IPython 0.11 that I made while watching the excellent Jeff Rush videos on showmedo.com. Use it and enjoy. Here we go:

Part I - basic commands
var - tab completion of a variable that starts with prefix 'var'
who [int, str, ..]- list available variables, or just those with the give type
whos - a table of all the variables, their type and values
psearch var* [type] - search for variables using the pattern and possibly type
reset - clear all variables
logstate - has the logging been started or not
logstart - start logging into (ipython_log.py by default)
logon - turn logging on
logoff - turn logging off
lsmagic - list all built in commands, called magic commands. These are prefixed with % to differentiate between variables if they have the same name.
magic - scrolling help about the magic commands.
cmd? - overview of the command, e.g lsmagic?
cmd?? - more information about the command including source code
var? - information about the variable
page obj - pretty print the object
func arg1, arg2 - automatically adds parentheses and calls func(arg1, arg2)
/func - same as func()
, func arg1, arg2 - same as func("arg1", "arg2")
help(keyword) - manual pages on keyword (module, function, etc)
help() -> topics - lists all the help topics
pdef func - shows the function signature (list of arguments it takes)
pdoc func - prints doc string for the function
pinfo func - same as func?
psource func - shows the source code for the function
pfile func - opens the source file with the func
edit -x func - opens the source with default editor on the line with the function

Part  II - navigation and the shell
Analogous to standard shell commands there are pwd, cd, pushd, popd, dirs Tab completion also works with these.
bookmark name [path] - bookmarks the current directory or the given path
bookmark -l - lists all saved bookmarks
bookmark -d name - removes bookmark name
dhist - prints the directory navigation history. cd can take numbers from that list as argument, e.g cd -2
!cmd - runs cmd as a shell command, e.g !ls
alias - lists defined aliases for shell commands we can use
alias newname cmd args - creates a new alias with newname as name for the cmd with args
unalias name - removes alias name
var = !cmd - store the output of cmd into variable
pycat name - prints the highlighted contents of the file
run script.py - runs a python file called script.py and prints the output. Also the functions, variables and modules from the script REMAIN in our namespace!
run -p script.py - run the profiling on the script

Part  III - input manipulation
ctrl+p, ctrl+n, arrow keys - previous next command from history
_i, _ii, _iii - prints 1,2 or 3 previous command
_i[X] - prints command number X, e.g _i1
In[X] - prints X-th input commands
hist [N1-N2] - prints a list of previously typed commands, or N1 through N2 previous commands
macro name cmdA-cmdB cmdX - defines a mactor that can execute commands from the history
print macro - prints a macro
edit file - opens up the default editor to edit a file
edit [N1-N2] - edit the history N1 through N2
save file N1-N2 - saves the historey N1 through N2 into file.py
cpaste - paste in source code without, IPython will not format it.
Out[X] - prints the X-th output if it exists
func; - putting does not echo the return of the function and does not put it into Out dictionary



Note! The following commands that Jeff uses in version 0.8.1 do not work in IPython 0.11:
store var - save the variable in profile for future use
p var - shorthand for print
exec cmd - execute a command
runlog - executes the IPython log
