Python, keep successively increasing longer list
Suppose I have a
listname=["john" "mary" "anne" "lisa"]

I want to generate the following as output

john
john mary
john mary anne
john mary anne lisa


Is there any way to do this?
print listname[0]
print listname[0] listname[1]
print listname[0] listname[1] listname [2]
.......

what is a smart way of putting this into a loop structure? Thanks.

Code:
for i in range(0, len(listname)+1):
     print ' '.join(listname[0:i])

Code:
awk -F\" '{for(i=2;i<=NF;i=i+2){a=a" "$i;print a}}'
