Adding a SOAP header to a SOAPpy request

Does anyone know how to do this? I need to add a header of the form:

value1 value2

From stackoverflow

• As the question is phrased, it's hard to guess what the intention (or even the intended semantics) is. For setting headers, try the following:

  import SOAPpy
  headers = SOAPpy.Types.headerType()
  headers.value1 = value2
  

  or

  [...]
  headers.foo = value1
  headers.bar = value2
