I subclassed StrPrinter to define my own printing of some of my
classes, and I can't seem to make xsym("*") work. I keep getting a
UnicodeDecodeError. Here is a code snippet of what I'm doing:
....
else:
if i == 0:
if isinstance(e.dict[k], Add):
s += '(' + print_pydy(e.dict[k])+\
')' + xsym('*') + k.__str__()
else:
s += print_pydy(e.dict[k]) + '*' +
k.__str__()
i += 1
else:
....
And here is the error I'm getting:
File "t.py", line 56, in <module>
print 'print A[1]', Vector((1+sin(q1))*A[1])
File "/home/luke/lib/python/pydy/pydy.py", line 254, in __str__
return print_pydy(self)
File "/home/luke/lib/python/pydy/pydy.py", line 1157, in print_pydy
return pp.doprint(e)
File "/var/lib/python-support/python2.6/sympy/printing/printer.py",
line 118, in doprint
return self._str(self._print(expr))
File "/var/lib/python-support/python2.6/sympy/printing/printer.py",
line 143, in _print
res = getattr(self, printmethod)(expr, *args)
File "/home/luke/lib/python/pydy/pydy.py", line 1102, in
_print_Vector
unicode(')') + xsym('*') + unicode(k.__str__())
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position
11: ordinal not in range(128)
Removing the xsym('*') gets ride of the error, but then I don't get
the small dot. I tried calling unicode() on each of the other terms
in the concatenation, but that didn't fix it.
I have search a lot online and have found many pages acknowledging
this error but none discussing how to fix it. Does anybody know what
I need to do in order to take care of this?
Thanks,
