enumeration code help

[sar]

Hi there, I am a new user of python and just want to know if there is anyway to shorten by below code in a way that I can multiply all records with a single value. At the moment I am selecting every single rec and multiplying it individually.

newList = []
for idx,rec in enumerate(tmp):
    newList.append ((rec[0]*2, rec[1] *2, rec[3] *2,
    rec[4] *2))
