Comment:
This works fine now after an explicit import:
{{{
sage: is_SymbolicExpressionRing??
Type: builtin_function_or_method
String Form:<built-in function is_SymbolicExpressionRing>
Definition: is_SymbolicExpressionRing(R)
Source:
def is_SymbolicExpressionRing(R):
"""
Returns True if *R* is the symbolic expression ring.
EXAMPLES::
sage: from sage.symbolic.ring import is_SymbolicExpressionRing
sage: is_SymbolicExpressionRing(ZZ)
False
sage: is_SymbolicExpressionRing(SR)
True
"""
return R is SR
}}}
