Here’s something I didn’t know possible in Python: iteration over more than one iterable in a list comprehension:
This is a companion discussion topic for the original entry at http://amir.rachum.com/blog/2012/07/14/double-iteration-in-list-comprehension/
Somewhat related to list comprehensions: A few months back I found out you can write multiple ifs one after the other and they'll be interpreted as if there was an and between them:
[i for i in xrange(10) if i > 3 if i < 6]
It's probably an anti feature as less than 10 people in the world know about it's existance.
Holy shit Alon, you blew my mind :)
I completely agree it's an anti-feature, but it's interesting to know that the syntax is allowed.
I actually used this a few days ago. I wanted to see if it'll pass our code review. It did, not questions asked :)
