Rules to Python one-liners

Question

I have been trying to get into one-liners.
I am opposed to them from a readability stand point, but they are cool and fun and make me feel like something else ;)
But, I get stuck more often than not.

So, my question:

Are there rules to one-liners?
Is there specific one-liner syntax, in such that there are rules in Python (perhaps non standard rules) that are catered towards one-liners?

Also, tips and tricks are welcome

Answer 1

Look up list comprehensions, generator expressions, lambda functions, ternary syntax and built-in functions. Those r the techniques used most often for writing one-liners. You should also get yourself acquainted with the star operator and double star operator (for dics). That's about it I think.

But honestly, it is usually not worth it.

Answer 2

i very rarly use them. Mostly I will use them if I am trying to generate something on the fly in a code “like a Lambda situation” but nothing else. I agree with the guys. Hard to read, maintain and I hate seeing them in a source code that is not mine, means hours of tail chasing.
