Hi, I need help on the following. >From the list of assignments: assignmentslist = {LHS1 = RHS1, LHS2 = RHS2, LHS3 = RHS3, ..., LHSi = RHSi, ..., LHSn = RSHn} I need to extract all the left hand sides (symbols) within a list like: lhslist = {LHS, LHS2, LHS3, ..., LHSi, ..., LHSn} Where the left hand sides are all symbols and the right hand sides are any expression.
