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
