New issue 1971 by jensen.oyvind: StrReprPrinter fails with TypeError
http://code.google.com/p/sympy/issues/detail?id=1971
The following script:
"""
from sympy import sstrrepr, Basic
class A(Basic):
def _sympystr(self, p):
return "printing A"
print sstrrepr(type(A()))
"""
fails with a TypeError:
Traceback (most recent call last):
File "t.py", line 7, in <module>
print sstrrepr(type(A()))
File "/home/oy/git_workingdir/sympy/sympy/printing/str.py", line 429, in
sstrrepr
s = p.doprint(expr)
File "/home/oy/git_workingdir/sympy/sympy/printing/printer.py", line 216,
in doprint
return self._str(self._print(expr))
File "/home/oy/git_workingdir/sympy/sympy/printing/printer.py", line 232,
in _print
return getattr(expr, self.printmethod)(self, *args)
TypeError: unbound method _sympystr() must be called with A instance as
first argument (got StrReprPrinter instance instead)
