Magic Functions

Timing

%timeit (time line)
%%timeit (time block in lines below, same line = not timed setup)

importing other jupyter notebook

run.ipynb:

% run 'lib_testprog.ipynb'
testfunct()

lib_testprog.ipynb:

def testfunct()
    return 1

if __name__ == '__main__' and '__file__' not in globals():
    print(testfunct())

sharing variables between notebooks

test1.ipynb:

variable = 'testdata'
%store variable

test2.ipynb:

%store -r variable
print(variable)

hints:
- use "global" in functions

Autorun notebooks on startup

simple, but no start/stop control later

/home/user/.ipython/profile_default/startup/startup.ipy

#!/usr/bin/ipython

%run /srv/python/script_a.ipynb

complex, with full control

/home/user/.ipython/profile_default/startup/startup.ipy

#!/usr/bin/ipython

%run /srv/python/startup.ipynb

/srv/python/startup.ipynb
