what is wrong in the code written inpython

Given that the infile contains:
aaaaaaa"pic01.jpg"bbbwrtwbbbsize 110KB
aawerwefrewqa"pic02.jpg"bbbertebbbsize 100KB
atyrtyruraa"pic03.jpg"bbbwtrwtbbbsize 190KB
How to obtain the outfile as:
pic01.jpg 110KB
pic02.jpg 100KB
pic03.jpg 190KB
My code is:
with open ('test.txt', 'r') as infile, open ('outfile.txt', 'w') as outfile:
for line in infile:
lines_set1 = line.split ('"')
lines_set2 = line.split (' ')
for item_set1 in lines_set1:
for item_set2 in lines_set2:
if item_set1.endswith ('.jpg'):
if item_set2.endswith ('KB'):
outfile.write (item_set1 + ' ' + item_set2 +
'\n')
But the code produces blank file. What is wrong with it??
