  • %%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)
