How to take out single element out of list in python?

I have list as follows:

list = [u'windows 32bit', u'i7', u'5Mb', u'energenie_eu', u'nvidia_970']

I want to take out value '5Mb' out of it. So, suggest me how can i take out value '5Mb' seperated from the list and have list as :

[u'windows 32bit', u'i7', u'energenie_eu', u'nvidia_970']
