 >>> l1=['wicky', 'wacky', 'woo']
 >>> l2=['hip', 'hop', 'hoo']
 >>> zip(l1,l2)
[('wicky', 'hip'), ('wacky', 'hop'), ('woo', 'hoo')]
 >>> pairs = zip(l1,l2)
 >>> key,value = pairs[0]
 >>> key,value
('wicky', 'hip')
 >>> d={}
 >>> d[key]=value
 >>> d
{'wicky': 'hip'}
 >>> d={}
 >>> for key,value in pairs:
    d[key]=value

   
 >>> d
{'woo': 'hoo', 'wacky': 'hop', 'wicky': 'hip'}


Or shortly:

 >>> d={}
 >>> for key,value in zip(l1,l2):
    d[key]=value

   
 >>> d
{'woo': 'hoo', 'wacky': 'hop', 'wicky': 'hip'}
 >>>
