printing out elements in list

[micklee74 at hotmail.com]

hi

i have a list with contents like this
alist = ['>QWER' , 'askfhs', '>REWR' ,'sfsdf' , '>FGDG',
'sdfsdgffdgfdg' ]

how can i "convert" this list into a dictionary such that

dictionary = { '>QWER':'askfhs' , '>REWR' : 'sfsdf' , '>FGDG',
'sdfsdgffdgfdg' }

thanks
