[Tutor] for loop

I'm experimenting and would like 'yes' to be printed only if 5 is not in
the list, but I want to look in each list. This prints out two yeses.
How do I get it to print just one 'yes'?

x = [[1,2,3],[2,4,6],[8,4,5,6],[9,8,7]]

for num in x:
    if 5 in num:
        break
    else:
        print 'yes'

Hi, I read the code and consider for a while, you can try it :

x = [[1,2,3],[2,4,6],[8,4,5,6],[9,8,7]]
print [ e for e in x if 5 in e]
