Python does not come with any SOAP stuff.  However, Twisted also does  
SOAP and there's also a couple blocking implementations at:  
http://pywebsvcs.sourceforge.net/

With SOAPpy (which I think bbum used, perhaps an earlier version) you  
would do something like this:
 >>> from SOAPpy import WSDL
 >>> proxy =  
WSDL.Proxy("http://www.xmethods.net/sd/2001/ 
CurrencyExchangeService.wsdl") # this blocks
 >>> print proxy.getRate(country1='us', country2='canada') # so does this
0.7414
