Hello Codeforces,

I started learning Python a week ago, and I've just solved my first problem using it. However; I was surprised by the huge execution time and memory for a very trivial problem, which makes me doubt if there's any effective tricks/advice to follow when using Python for competitive programming.

Wouldn't it be nice if we just collect some of those ideas here or somewhere else and make it available for everyone?

Please don't comment such comments like "The only advice I can tell is Don't use Python for competitive programming" :P, this is serious :)
