class_docstr: Returns the lambdified function.
  
  Explanation
  ===========
  
  This function uses experimental_lambdify to create a lambdified
  expression. It uses cmath to lambdify the expression. If the function
  is not implemented in Python cmath, Python cmath calls evalf on those
  functions.
code: def __init__(self, args, expr):
      self.args = args
      self.expr = expr
      self.lambda_func_1 = experimental_lambdify(
          args, expr, use_python_cmath=True, use_evalf=True
      )
      self.lambda_func_2 = experimental_lambdify(
          args, expr, use_python_math=True, use_evalf=True
      )
      self.lambda_func_3 = experimental_lambdify(
          args, expr, use_evalf=True, complex_wrap_evalf=True
      )
      self.lambda_func = self.lambda_func_1
      self.failure = False
