Python - Random Sample Generator

so my first question on Stackoverflow. Please be kind:) I'm very new to Python - but each day I'm trying to get better.

I'm trying to address this questions: "Generate 1,000 random samples of size 50 from population. Calculate the mean of each of these samples (so you should have 1,000 means) and put them in a list norm_samples_50"

My guess is I have to use the randn function - but I can't quite guess on how to form the syntax based on the question above. I've done the research and cant' quite find an answer that fits. Would appreciate any help.
