Comment #19 on issue 1297 by [email protected]: examples don't run
http://code.google.com/p/sympy/issues/detail?id=1297
maybe put the "import sympy" inside a try block and utput info if it fails
would be a
good idea.
try:
import sympy
except ImportError:
print "Please install SymPy first"
sys.exit(-1)
i don't think it makes the code much more complicated and it gives a nice
feedback on
why the examples failed, as this will probably be the first thing new users
look at.
