and how about adding "IF" into the mix ?
as in :
a=0
dict= {10: ['a',1,'c'], 20: ['d',2,'f']}
for i in dict:
p+= 10 if dict[i][1] in [1,2,3,4,5] else 0
can i "squish" "for" and "if" together ? or will it be too perl-ish ?

Hello,
i wonder how can i accomplish the following as a one liner:
dict= {10: ['a',1,'c'], 20: ['d',2,'f']}
p = 0
for i in dict:
p += dict[i][1]
Thank you

Catching all exceptions in a try-except block is almost always a bad idea.
You can't tell the difference between an exception that you are looking to
handle and an exception that should cause your program to crash and burn
(because something is wrong). It's best to catch a specific exception.
