I've tried this before, and gave up out of frustration. Most of my code
is stored in different modules and imported into little executable
scripts that either prove or graph something.
This isn't a very good problem report, but "everything gets screwed up"
when you begin importing from other modules that may or may not be
preparsed.
Anyway, in this case, I'd like to define 'f' in one module
(piecewise_data) and import it into the main script (piecewise_test).
$ cat piecewise_data.sage
from sage.all import *
x = SR.symbol('x', domain='real')
interval0 = (0, 0.5)
function0(x) = 4.0*(x - 0.5)**2
f = piecewise([[interval0, function0]])
$ cat piecewise_test.sage
#!/home/mjo/bin/sage
from sage.all import *
from piecewise_data import *
print "f(1/2):"
print f(1/2)
print ""
$ sage piecewise_test.sage
Traceback (most recent call last):
File "piecewise_test.py", line 6, in <module>
from piecewise_data import *
ImportError: No module named piecewise_data
$ mv piecewise_data.sage piecewise_data.py
